S3#7. We Design the Ultimate Catamaran! Let the fun begin! Portofino 52.
HTML-код
- Опубликовано: 1 мар 2023
- Join Barefoot Doctors Sailing as we take the next step in the creation of the ULTIMATE Catamaran for us! We share the details of the further design processes for the steering station and how to make your cockpit and steering station waterproof.... We also run through the cost and key features of the Portofino 52 and why it is such a unique design.
We also share the reality of sailing in rough weather with water all over the aft cockpit seats and having howling winds and sea water pounding us in the steering station because of the absence of drop downs and we see how water just falls into the cockpit from the big space of the steering station.
We also share an update on the building progress of the Portofino 47 and join us as we visit amazing places in Dubai and fulfil one of Eli's long term dreams to go for a balloon ride over the Sahara Desert. That is followed by breakfast in a Bedouin camp, camel rides, falcon flying and being the Bedouin Princess (Eli - not John!)
Some come Barefoot with us on this exciting journey!!!
Binge watch and come barefoot with us as we travel and explore the planet, mostly from the water but sometimes through the minds of others as we provide aid and support where needed through the amazing TUFMINDS solutions!
WHAT IS TUFMINDS
The free TUFMINDS program is released as a smartphone program under the Exqisit Life Foundation Charity, a registered not for profit and requires financial support to fund the free program. TUFMINDS saves lives by intervening at the point of suicide and pulling everyone to higher levels of mental resilience, wellbeing and functioning. it also creates better attitudes, resilience and coping - all very important for sailors facing difficult situations at sea.

So excited for you both!
My husband and I are watching saying... "I want that too! And that! and That!! These two know exactly what we want. It looked like there were so many thing we had to give up for some performance. No longer. I am curious about a rooftop chill lounge, not a nav area, but cocktail spot."
I would love to talk to the Portafino folks. We are 1 year away or so. Sounds like you are two years away from your boat.
Closing up for weather is huge! I love the idea of the window, it would necessitate covering up the lines, love that even more. they would last and last.
Looking forward to seeing all your options and all the details.
We are along with you for the ride!! Lets go!
Great to have you along with us!!! Our completion date is expected to be Christmas next year ( sounds better than Jan 2025!) We are planing to have flat cushion on the saloon roof that can pull up as back rest so we can use it when we want…
The build time is 2 years but Portofino does have a waiting list already so don’t wait too long if you are serious… All the best, Eli and John
@@barefootdoctorssailing8567 we emailed this Portofino morning. I wonder if they are going to Cannes….
If you covered all the lines going into the cockpit that may allow for a window. I can’t imagine how it will work. But excited to see how they figure it out. It really is a problem.
Also curious to see how you like the stairs to the top deck. We just chartered a leopard in the Abacos. It was really awkward to get to the sales. You had to go all the way up to the front of the boat, climb the stairs. Also awkward to get to the flybridge. So I’m really curious how you’re going to handle the stairs. You have so many other great ideas. I’m sure you’ll like this one out of the park too
As a naval architect I'm absolutely with you about the choice. Thought myself about retractable centreboards. This will give you great performance (hopefully) and even allow to change the longitudinal centre of appendages. I'd wait with the choice of the propulsion and electric systems as well. There are plenty of new battery technologies on the way. A Canadian company has announced a salt battery to be ready for production this year. I'm working on the same software by the way. Recognized it on the first screenshot with typical appearance.
Blade cells offer advantages over round cells for Lithium batteries.
But Na Al and Sulphur technologies offer huge advantages over Li tech in terms up to 4 times the capacity faster charging and temperature tolerances...especially in the lower end..
They are also coming into production this year.
The motor regen generators are massively powerful and compact already in the automotive industry.
Thanks for that Andre and yes we believe that there will be major advancements between now and when we launch so we hope to get the best of what is available in 2 years time!!! Keep the info flowing to us please!
@@barefootdoctorssailing8567
The Basalt hulled protype did a ten month Atlantic circumnav including coming home via Newfoundland Iceland Norway etc . Using hybrid power systems they used aircon and heating as and when and used 800L of fuel for the whole trip.. the rest came from solar and regen a bit from a wind turbine. You will havet search for the article or any external links just get blocked and comments deleated.
Meantime Daz cat are proposing a cruising vessel which melds features of the R550 and their performance Dazcats.. interesting.
Starting to like this boat more and more.... it ticks a hell of a lot of boxes. Congrats with your choice. As far as the cockpit windows: you might want to look into the solution the Amel Super Maramu has: a solution where the windows are split horizontally and slightly overlapping. The bottom part is fixed and the top part can swing open. For the OSCAR: Don't doubt, do it. I have sailed over 2.,500 miles with it and it picked up things I was not able to see. From small dark fishing buoys to unlit boats at night. I'm having an EchoPilot 3D installed for safety as well, no experience yet but looks promising. Underwatercamera's I have looked at them but nobody could convince me the lenses would stay clean over time. Best of luck and fun with the build of this beauty.
Thanks Hans. NIce to hear that some things work eg OSCAR! The advice Rafaele gave us about the underwater cameras is that they need to be removable so they do not grow mould while they are not being used and just pushed out for use....
You have a lot of good design ideas which I’m sure the company appreciates and will use.
Thanks for your kind words Tony! It is so good for us to get a boat where our desires are being added!
I really love the design of the Windelo, enclosed, protected front steering station. Rear cockpit area and coach roof beautiful and protected. Running rigging much straighter and shorter runs. Good luck with the build! 👍👍👍👍👍👍
Yes that is the advantage of the workspace being at the bottom of the mast and I have never sailed with that system but as you say it is good for the reduced turns on all the lines but you are right there in all the spray at the front of the boat.... I would like to actually sail on one in bad weather to see how it works!
@@barefootdoctorssailing8567 There are some decent vids showing a reasonably enclosed area. But you are right nothing beats real sailing experience 👍 ( also all the instruments are out of the weather )
Oh my goodness! 😮 The safety additions and construction of this catamaran will bring you both the added security of knowing you are in the safest boat on the ocean! There is no price you can put on your safety and I truly believe dollar for dollar you are spending wisely. When finished you both will have raised the bar on future catamarans built by other companies. They will need to “step up” their game to even compete with Portofino. She is so beautiful even if it’s just in the blueprint stage. I’m excited for you both and so grateful you are taking us along on this journey! Thank you so much 😊 I loved the balloon 🎈 ride and so happy Eli got to check this off her list. I’m sure this won’t be her last balloon 🎈 ride as she has now got a taste of a highly addictive adventure. Both of you at dinner were absolutely gorgeous! You both looked happy and healthy. 😊 Until next time, keep the wind to your back and stay safe!
You are very kind Mango, thanks!!!
Hi luv the boat . A solution for keeping water out of cockpit , have a flexable vertical waterproof curtain on tracks both. top that will start on vertical cabin and go around to outside of steering station . This is tough to explain but it will have tracks that follow your standing platform top and bottom closing off 4' that is open to cockpit . Hope this helps
The top being underside of hardtop so curtain will be on angle from top to standing platform
That's a great idea! I presume you are meaning that the curtain goes from the floor to the cockpit roof with track at bottom to make it fully waterproof?
We were planing to have drop downs with waterproof and sun shades but having a track to seal it completely is a great idea...
Hi Folks, Erik Aanderaa has that oscar system installed on his boat, valuable for him as he is a solo sailor and as a couch based sailor can certainly see the safety benefits. Great video, ballooning looked fun.
Thanks for that, Ian! Glad to know OSCAR worked well and thanks for the kind words.
Great looking design and love the fact that experienced cruisers are able to assist in the design process. Seems like so many boats are designed by Manufacturers with their goals in mind vs Sailors. On the steering area, I am not a huge fan of the balance versa-helm. It comes across as somewhat gimmicky to me. It isn't that solid, and rather than 1 great helm, it is two so-so helms. I personally would not dedicate so much area to a 2nd steering wheel in the saloon, how often do you hand steer? You can make adjustments via autohelm, if needed, at a nav station that also functions as a desk and multipurpose area. You are really only protecting against the times it is bad weather and you need to hand steer. If it is bad weather, you will still need to work winches and trim lines, so I would focus on making that helm really good, functional and able to seal out the weather while you sail, as well as protecting the cockpit from overflow and spray.
I have often wondered if there is anyway to incorporate more of a dodger/hard window to the steering area for weather protection. It seems like the designer has some great designs and some sort of combination roll downs with a couple of folding windows could be a great solution for enclosing the steering area in foul weather. In good weather they would fold up flat to the inside of the Bimini/hard roof, and then fold down and lock in place for rain.
Btw, I doubt you remember, but we actually hung out and toured the HH with you in Annapolis in 2021 as you were starting your new search and interviewing them.
Can't wait to see this come together!
Nice to hear from you again and I remember you at HH! You make good points about the outer helm position so I hope we can get a really good solution as it is very important...
Who says "money doesn't bring happiness"
Congratulations 👏 can't wait for real yacht tour once you get it🤞🤞🤞 so exciting, I wish you both the very best of LUCK 🤞🤞🤞👌👌👌👍👍👏👏👏🤩🥰 ✌❤🍀
Thanks a lot!!! Glad to have you along with us for the journey!
More accurately, the wise use of money can bring happiness.
@@rumblechick73 Exactly!
So happy for you guys!!!!!!
Thanks for your support guys!!!
What a journey! Excited for both of you
Cheers Art!
sounds great guys
Thanks very much for following and commenting, Stephen!
Very good one, thanks 👍
Its a pleasure Billy!
Great plans! Beautiful country! Can't wait for your next adventures!
Glad you like them, Jero!
great show , loved Dubai !
Thanks a lot Roger for watching and commenting!
Epic! Really going to enjoy this one. You guys have certainly thought of everything. Thanks so much for sharing :)
Thanks for your kind words, Robbie! We are still thinking a lot though so not everything is sorted yet... But that's life!
congrats again - very good vlog - an interesting mix - boat facts - boats and a little touristy thingy
Glad you enjoyed it, Jim!
Great fun. You are truly living the life. I am so happy for you.
Yes we are, thanks very much Limeric!
Great to see the 47 coming together. Regarding instruments, direct sunlight onto a graphic screen will overheat the device and make reading the information more difficult. In the movie industry, this problem is ever present for screens large and small. The solution is a detachable hood. Commercial versions may be available, but custom hoods will fit perfectly. They are cheaper and easily replaceable. Use velcro, coroplast and tape. Attach the hood whenever needed.
Thanks Action Man! Yes that is a good idea if the hood and be fitted and move up and down as required! We we=il see what the designers come up with and if it can be workable....
Magical, I love Dubai!
Thanks David - yes quite a surprising place!
Nice life project, I like the detail, and I like the novel idea of swing-up keels/daggerboards.
I have an Aluminum 15-meter masthead cutter monohull with two waterproof doors and 2 bulkheads. I fully agree with Aluminum as a boat-building material from a personal industrial accident experience when my boat was on the hard stand and a fiberglass boat knocked my boat over when I was antifouling.
Both boats had suffered major damage. The main difference was mine was dented, and not holed, his boat's bolted-on keel pushed out of the center and the slipway cradle I beam went straight through his hull and ripped out the galley like an eggshell. Object lesson, I will never own a fiberglass boat. Good luck with your great boat-building adventure. SV Skoiern IV
Sounds like a lovely boat and great story John, and glad to know we are on the right track!!!
Greetings Doc's just a thought about your pilot position enclosure. a small hard pilot house (all sides ) like structure with the same negative windows that on the coach roof and a pantograph (popout) door, access to cockpit below would remain accessible?! It would look integral to the design aesthetics and provide the protective desires for both you and gear. that said the windows could be dropped down like in an old Jeep / landrover or slide open for good weather days and depending on glass used you could install IR film (if the glass can't be ordered with it) this will cut thermal heat by 90% without any loss of visibility! companies like trendmarine make the doors, windows etc. just for visual idea take a peek at (of course scale to your cat's needs) wellcraft 355, Arctic boats, sunreef and sunseeker use the popout doors, metal shark patrol boats, rafnar rib, some river boats etc. thanks for sharing your journey, Blessings.
Thanks Arthur for all that info! We did reply to this comment some time ago but it seems to not have posted... All great ideas and points and we are still working through the details of the steering station but we think most other things are solved....
That's the Burj Al Arab in the picture but the details of Burj Khalifa. You're both looking well & happy, imagine moving forward with the 52 is a big part of that.Ergonomics of the winches and line/sheet management on the cabin top at the helm will be very important and looks like you're moving in a good direction. The Dubai ballon ride is an early start but worth it. Loving the videos, thanks for sharing. Best wishes, Jason Yvette & Jack.
Thanks Jason! Eli says "I told you so" as she had in her mind that the Burj Khalifa was elsewhere but I only remembered the "Burj" part! I bow in reverence to the wisdom beside me!!!
Awesome build, solid, great.
Thanks for the support David!!!
I love the vibes of both of you, this will be amazing and you deserve all the good things. About the steering system, I like the design from Balance, maybe ti could work for your boat too. Cheers from Cancún.
Thanks Nicolas, yes the Versa helm impressed us too!
Wow... I'll say it backwards woW.... very exciting times... Gr8 to see you both happier and I reckon your 2 (or so) years will go fast eh Enjoy.
Thanks ned! Hopefully it will fly because we have lots to do!!!
I’m really excited for this build! Safety, safety, safety. Those options for safety will be worth it to protect your investment. Not to mention, the piece of mind!
I have to say, Balance catamaran’s Versahelm is truly a wonderful solution that you may want to consider with your Portofino 52. I don’t think it’s patented, as there have been many tilting steering columns.
All the best to you two!
Hi Jay - yes we really liked the Versa Helm and we have discussed it although we are having a second steering position in the front of the saloon but the VErsahelm may still help to get the wheel out of the road or out laterally to see the sails directly...
@@barefootdoctorssailing8567 . A second steering system would be great. Then the sliding overhead door should keep the water out. Nice!
Love & Respect!......btw; perhaps a "cacoooning" curved safetyglass/lexan could be designed for upper steering position... small concentric tracks for each piece attached to overhead and partially on roof. Or how about mini winshield centered on steering position with wing sidea track mounted that could be parked behind min windshield.....
Thanks Lincoln, nice idea. I know some motor boats have angles windscreens as you suggest and they are relatively easily removable for the French canals so that sort of thing could work...
Thank you for another great video. Congratulations on ordering your new boat.
Some thoughts about your boat and previous comments.
Folding keels and rudders are great but please verify that they will function after an angled strike. Few impacts will be aligned directly with the direction in which they fold.
Cockpit daybed: Adding sunbed style backrest brackets to lift part of the mattress to a backrest may facilitate common seat width.
Sealed air voids made in Dubai should have little moisture for condensation to occur unside. Please ensure you know how the builder verifies sealing of these voids. Pin holes in welds are common. Holing a sealed void would be most likely low in the void and water intake would be limited to just above the hole by the air above the water. Many pontoon tanks have holes in the base to adjust the pontoon standing height. If needed compressed air is blown into the holes to raise the pontoon.
Lightning protection: I've designed lightning and earthing systems for a few hundred Australian installations including for areas exceeding 180 thunder-days per annum. Having seen severe damage to a building fitted with a proprietary system, I suggest you avoid such systems. I suggest you ensure your system conform to Australian Standard: AS1768-Lightning protection.
An aluminium vessel with an aluminium mast is an ideal situation. I suspect your masthead will be more than 45m above the sea. Thus in addition to top strikes, the mast and its stay wires may be exposed to side strikes. The mast surface may be damaged by such a strike but that should be all. I assume the stays will exceed 10mm dia. but if they don't I suggest you ensure they are at least 10mm dia. but preferably 12mm or more. Adding a 10mm dia. 600mm to 1.5m 316SS or al rod above your masthead would minimize direct strikes to your masthead. I assume the builder will conductively mount suitable 316SS plates submerged below water level on the inside of each hull. The shorter the distance from any lightning strike to the sea the better. Should you desire more info. please comment accordingly and i will email you.
All the best for your boat build and for your journeys during the build. Enjoy life and keep smiling.
WOW Pinetree, that is great information! Those run head leaks are already being checked for in the #1 Portofino 47 so hopefully that will be done through out...
We are still to look into the details of lightning protection and it does seem that some providers are more intent on the money they can make from using unproven devices than actually finding tiger evidence... I will check the details of the shrouds although our mast is about 25m long and few more metres about the water. It will be aluminium and we hope to break the wires taking any electric shocks inside the boat as we heard that was a common problem.
That rod to the top of the mast sounds like a good idea and I am not sure about the 316SS opkates under the water as the whole boat is AL... If you can give us more information about how to go forward and how you know all this stuff (your job?) that would be great. We want to investigate all the issues around lighting and then make an episode about it - do you want contribute to that too???
Hi Guys congrats on the new boat. As far as the helm station is concerned Sailing Zatara has a very good helm set up that is well protected and it is only about 16 or so inches above the roof of the cabin below. I was surprised that you are planning as high a set up to operate the boat from. Episode 113 is the boat tour of their Prestige 585 catamaran you can see the helm as they have it now. It appears to be lower than what I think you are planning on your cat. I found you today on my home page and I have subscribed woo hoo!!
Glad to have you one board, P Bear! The main issue with height is to see both bows from the steering position and that usually needs standing up a bit to see down to the bow level at the front. We certainly don't want the steering roof to be higher than we need (as it creates windage) but it needs to be higher enough to see well... Thanks for the comment and we will look into it. The steering station can be adjusted very late int eh build process so there is still plenty of time....
Okay, I downloaded the brochures from Portofino and started playing with the stern of the boat. Turns out you can add quite a bit of space if the hull stairs turn 90 degrees for the last step.
If the brochures are close extending the top also adds almost a meter, which is pretty cool, the extra space may make a slide over cover for the cockpit feasible.
With the stairs being turned access to the salon platform with ladders allows the tender platform to be used like a beach.
I would like your opinion on the drawings, It would be nice to see if they make sense, If you have a generalized email I can forward the picts if your willing.
-MG
EDIT: I can drop them in the sketchup 3D cloud, I thought I saw you using sketchup in the videos ... Its and option, I can put it under bare foot doctors as a title. So the photos are on sketchups cloud with the title Barefoot doctors cat...
Hi MG, thanks for the interest! My email is drjohnmcintosh@tpg.com.au . I don’t have 3d software and those that I used were from a meeting with the architects . Interested to see what you have come up with
I like the helm on the Dix 550! If beefed up with kelvar on the bottoms and carbon fiber reinforced cross bulkheads that boat could be great at a quarter or even fifth of the cost! But it,s a kit! Huge elephant to eat!! The helm is just behind the mast inside the salon and all lines are controlled in front of the mast! The 550 is the DNA used in the gunboats!
Thanks for that info Russell. I have never sailed a boat in that configuration and the advantages are the reduced pulleys and the more direct winching of the lines but I (personally) think that I do not want to be handling the lines so close to the crashing waves and spray at the front of the boat.... But as I have not done it, that is just a presumption but would hate to build a boat and discover that it is too exposed for our liking! We are happy with the line controls to the steering position behind the saloon bulkhead.
Many long comments below from your viewers! Just keep in mind...
Great design stirs the imagination and elicits ideas.
You are on to something with this boat ;)
Thank you so much 😀 again!
This is a really cool boat, and I really think the style is top notch, but is the seat in the aft area sitting on just the first step? Typically seating is done at about 450mm from the floor give or take for leg room. Its hard to tell, the models look right on the cad but some of the "pictures" look low?
I really like this boat, but for me I think I would add the extra 300 mm to the cabins and remove the steps going from the salon to the sugar scoops.
I would also move remove the poles and connect the center of the hulls at the stairs.
The slats shown in the 57 footer (where your steps are for top access) would make a nice accent. I would also extend the top to allow for more solar.
I really think turning the steps 90 degrees and going up to the platform would be cool, when the platform is in the water the turn steps functions as a seat on both sugar scoops.
Overall this looks awesome and I think your going to get pretty excited as the day finally arrives!
-MG
Thanks MG for your detailed comments. The renders do change the proportions a bit and I am sure that the seat height will be standard and we have been moving the steps to get a bit more space inside the hulls and a variety of things like that. Obviously some poles are structural esp under the mast but I can check with the architects...
@@barefootdoctorssailing8567 Great, I think you're going to love the boat. I reread my comments, it wasn't all that clear unfortunately. I know I said get rid of the poles, but really I meant widen the pole position by connecting to the beam in between the flip up door and the stairs.
The real reason for moving the poles (sexy curves) to the middle of the beam allows for the hull stairs and the flip up door to slide 300+ mm toward the stern. The 45 angle for the stairs that currently service the sugar scoops can get modified to be connected to the swim platform.
If I had the cad file I would give it a go for you. Your literally building the boat with all the goodies I could ask for... ah, well some day...
-MG
I was a bit critical when I first saw your polar's video and thought you were being taken for a ride by the builder. I have since watched a few more of your video and see you have more experience than what is first apparent.
The more I see of this boat, the more I like it. It looks like an awesome build.
Lots of features match a build I have one paper for a custom expedition catamaran. I am really surprised no other builder has built a boat similar stature yet!!
I'll be following the build, really interested to see if it hits the published numbers when launched. I'm really impressed with the built weight. I have a built weight on paper for a slightly larger build at 25t, although I am looking for a larger load capacity as an expedition boat.
Thanks for the comments and for watching Darren! And yes we will also be interested in the real performance figures after the boat is launched too! There are builders that do AL boat much lighter too although they are usually much thinner skins and less supports. The nice thing with AL is that each boat is a new build so each can be modified (within reason) to suit each owner for icebergs, performance, layouts etc...
Do you know 'ELCIE'?
Battery fire protection: Design battery compartment flooding feature. Hope you have already seen this idea Eg. Chris White’s 70ft Penmanship catamaran seen on RUclips, The O’Kelly’s Sailing the ULTIMATE Performance Cruising Catamarans. Timemark 9min45sec
Thanks Michael, you are right and we will be getting Lithium so this is really important!
It would be great if you could steal the Steering station off the Balance 482 love that idea. You have to put an under water camera on it that's on my dream boat list.
Thanks Tunnel Rat! We have been using that as an idea but there are somme practical problems that are preventing it from working - steering wheel , seat back to be comfortable and still having the winches and sheets above the hatch...
This is a great looking boat. Lots of unique innovative features. I am interested in how the centreboards will be reinforced. The ill -ated Gunboat 55 had centreboards and there were problems with the centreboard boxes flexing because the boards were a long lever supported in a relatively low profile centreboard box. I suspect that they can be made robust with aluminum and I am interested in seeing the design of the supporting structure.
Hi Gordon, thanks for that insight! Certainly it is easier to make it stronger with AL and the engineering calculations are being performed right now to make sure that there are no weak points anywhere...
This is fantastic. Thank you for sharing this great build. Does anyone do a retractable glass windshield?
Not that I know of, Kirk.... The closest thing is polycarbonate screens that slide up on the Hylas 55 (see earlier comment).
Really neat video. Living the life.
Take a look at the Mumby's rudders. There's some method where they have blocks of wood bracing the rudders. If they hit anything the wood breaks, the rudder floats free - undamaged (and tethered). Might also work for the swinging dagger boards. Sailing Life Jupiter YT Channel has a Mumby and has broken the rudder blocks.
Steps: When we go up or down a stair/ladder that we use all the time we tend to do it one way. So the alternating steps, left right, left right should work really well. I was once behind some Japanese hikers going up a mountain, they had to crawl scramble over some rocks. Slow. Because I was last I had time to think about it. So when it was my turn I just went zip zap zip, stood up on top. Some very amateur rock climbing moves. (Side bracing was the key. ) On a boat that's what I would always go for. Secure, quick. (The opposite of this are those grand but half height stairs. You can't quite take two, but just one seems like stutter stepping.)
Thanks again for your input Will! Good advice re steps. We have looked at the Mumby and their solution and the concept of sacrificial pins / wood are also used for the centreboards and rudders but using a compression fitting that releases under pressure, means that nothing breaks and the board / rudder can just be lowered again without any intervention or repair. SO that is the direction we are heading at present.
Its different but I like the Windelo cab foreword steering configuration. It's a performance cat and sirs high in the wearer with less spray than other configurations.
Thanks for following and commenting and letting us know that Edward. I always wondered how wet and antisocial the forward station was in bad weather.
The new boat is going to be amazing. You said in the last video to comment on proposed changes you were making, not sure that I like that you are making a fixed change to the bench seat below the stairs to fly bridge, I agree with what you said that it would be nice having this bench be wider to be able to lie down, rather make this a pull-out base to create the so called bed area and use the backrest as the pull-out mattress. Having a wide area for seating is going to be a huge problem when someone needs to sit back on that back rest, having it wide is ok but normal or double bed size is going to be very restricting long term. This way you will also need to leave the stairway you you propose. Cheers Chris
Thanks for the feedback Chris and your points are very valid. We have discussed the fact that a wide day bed does not work well as a seat as you have to sit way in and your legs have to be up - so it becomes a lounging seat only. And only great for those used to sitting in yoga poses so I'd better start practicing! Eli likes the idea of having a good day bed and yoga practice area and this is what HH55s have as well (so I presume it is proven...) It is not a double bed size and there is plenty of space in the cockpit and I prefer to have things fixed in place so they can't blow away... We will look at the dimensions again and double check how it will work. Ta!
Does the front cockpit door on the Portofino 47 and your 52 open in two parts - like a dutchdoor? I would think the recessed sloping glass open in and up separately. And the solid lower door opens out.
Floor plan layout idea: If the front cockpit door is centred on the front wall for symmetry - like the Sunreef50 - would add kitchen counter along the front wall for Eg. oven and coffee maker.
Thanks Michael for the input. The front cockpit door is one piece only as it needs to be watertight. It will be flat while the glass around it slopes outwards. Strength is very important here.
We will look into those ideas although there are limitations because we have the cabin berth on one side. We will see the options, Thanks
Looking forward to your choices along with the reasons.
Thanks Carol and nice of you to follow and comment!
Heat and electronics never mix well but if you have the Dash Board made so it has a Over Hang like a Veranda that will shade The Screens and run a Ac Duct behind that screen to cool the inside area of the Equipment might Work ask the Engineering Guys. lol
Good points, thanks Moz!
Balloon rides have the most unglamorous entry and exit. 🤣🤣🤣🤣After Christmas, we took an unplanned trip to Ft Myers Florida, we went to where hurricane Ian had hit the hardest, we thought they needed our tourist $$. We actually went on a "day sail" well, 2 hrs🤣 on a 50' cat, it had a front tramp ladder, I thought it was amazing, but an FYI, we were close to the beach and it wasn't too rough out, but the ladder was thrashing up and down with every wave, crew had to hold it down, two stood halfway down off to each side and the other was standing on the bottom rail. If they had of had some brace to secure it rigid, that might have helped it from bouncing up and down. The other problem was, you can't go down facing the ladder because it would have smashed you in the face, you have to exit facing forward and there really was nothing to hold onto. Perhaps some kind of brace to keep it rigid that could also double as something to hold onto. Love following this journey.
Thanks for that info Amanda and for the comments. I know the motor boats that deliver folk to the beach often have a ladder over the front to make it easier but that certainly does not sound easy...
@@barefootdoctorssailing8567 This was a sailing Catamaran, the concept is great, with some improvements would be amazing.
Hi! Having never been on anything other than a ferry..... Can i suggest you check out car dashboards. Some (Audi, Rangerover) have tiny hydrolics that drop their dashboards out of sight when required. I will expect a mention when you adopt this genius idea. Can't understand why i love watching your channel. I can't even swim.🤦🏾♂️🤷🏾♂️😭😭😭
Thanks for the tips, Andrew! Perhaps you should learn to swim!!! But yes already today we have been discussing gteh rotate out and in of the dashboard with Raffaele - all because of you!
Looking forward to seeing your solution. The swimming lessons may become a necessity, as we're planning our own life changes. 🤦🏾♂️
Love it. If they made a power cat I'd buy one
Just put your order in - it's only a boat without sails... Of course slightly different hull shape and bigger engines but if you can build a yacht, you can build a powerboat!
The Oscar and forward facing sonar combined will give you the best collision detection. Lightning detection people are very suspicious about if it works at all. Personally, I would also go for it.
Thanks Patrick - yes we are suspicious of the $15000 lightning protectors but we have about 18 months to investigate, check any new research and see what evidence there is...
Check the work of Dr. Ewen Thomson and his solution using Seidarc conductors that discharge at the sea surface, NOT plates underwater and the proper down conductor from the mast (assuming aluminium).
Better system based on real research and a fraction of cost compared to $15 to $20k.
Silly me, doh! An aluminium boat with aluminium mast does not need conductors, the whole boat equalises the surface charge cloud. Just don’t get a carbon mast!
re steering position. Watching your video of you at the wheel makes my head shake.
About 25 years ago I was chatting to Richard Ward, owner of Seawind cats about this problem. I told him about a cat I'd owned where steering was under the solid awning roof, the visibilty was excellent because saloon windows were large glass. The window in front of the helm was glass and removable. He incorporated this when he introduced the Seawind 1160. Have a look at the new large Seawind he's offering today. Extremely sensible solution
Thanks Rod, yes that boat does not have the cockpit enclosure at all as we did not have the time to get it done after taking it over in France. We have interviewed Richard about the 1600 and he was a really nice guy and also reached out to support us after the fire. We will go back and look at the solutions he has created with the other boats then.
Hi again Rod, What is the "large Seawind" that you mention. All I am aware of is the 1600 which we have been on but that is an older design so please let me know what model you are talking about....
@@barefootdoctorssailing8567 Oops, I was mistaken, RW has gone back to putting steering out under the stars and wind and rain and spray and sun LOL.
Should have configured steering similar to 1260. Out of the elements . I hate the cat setups where steering position is a big pimple on the roof.
Watching one of your videos i'm sure your over that too. Have fun.
this is looking like a dream I had of the ideal catamaran...only changes i would want would be the helm station mounted forward and inside a la Windela 54 /kinetic 54/62/Gunboat 68/ Chris White 72.,and with manual tillers as a backup .. (the idea of being soaked from an exposed helm station is not appealing at my age ) and a deck located master suite like the JFA 85 .. do like the swing away centreboard type daggerboards ..genius idea ....those underwater cameras are a great idea ..entirely doable ...tempered or laminated glass..all great practical solutions ...you may want to look into the tesla lighting protection system..one outfit is CMCE... it is a 100 year old patent but indications seem to be that it may work..it is expensive but probably better to have it that not
Hi Buster and thanks for the info and the support! We already have an internal steering station although the lines do not lead to the front cockpit like the WIndelo/ Kinetic/ Gunboat etc... We hope to use the inside steering station for the bad weather times and stay warm!
Thanks for the other info and we will hopefully be able to check all that out too....
I love your videos. My Fiancé and I are looking for something very similar. Any advice you can offer in connecting with them to find out more be be really appreciated! Thanks Rick
Thanks for the kind words Rick and if you want more info on Portofino, contact by email to Raffaele on info@portofinomarineservice.com or their website of the same name (no "s" at end of service....)
I think gunboat style steering setup would solve most of your concerns. It would also allow you to have more main sail by not having a raised helm. Gunboat moves the helm inside the cockpit keeping everything dry!
Yes that's a good point Wayne and Gunboats are significantly different from we are looking at. Thanks for the idea!
I am in love with your new boat hope you make it home to sail one year. ❤Did you ever get your insurance sorted
HI Green Eyes - nice to have you along for the ride! We hope to get it home in the future 7-10 years (!) and we are still locked in legal battles over the insurance...
Very nice your version, you should add the special bow thruster,
HI again, yes we are seriously considering the jet thrusters as they seem to work so well.
A thought for the steering station, from memory I believe the Hylas yacht has Polycarbonate screens that slide up into the roof, out of the way when not required. The slides are comparably light, don’t scratch or go milky in time, giving clarity of sight line.
Anyhow just a thought for fouling weather.
Thanks Peter, good info and I will try and check Hylas out!
@@barefootdoctorssailing8567 I had a sneaky look..
Hylas own video of 11months ago, Hylas 57. You can see the screens from the start of the video and description at 4:30.

Hi, Watching with lots of interest on the Portofino 52. Could you let me know the waterline length and the mast height. Cheers
Hi Ross, the LWL is 15.3m and the mast height is about 18m (from memory). Sail area of main 105m2, jib 67m2 and Code 0 160m2...
St Francis catamarans have tramp ladders, I know Anton du Toit have designed some custom aluminum cats with the tramp ladder too and I've have seen them on a number of day charter cats throughout the Caribbean as well. Such a neat thing to have
Thanks for that info P! The reason I specified that there were none to MY KNOWLEDGE was I though that someone somewhere probably had done it before and I have seen them on the powered charter boats all the time to off load their people off the bow while their engine says in safe depth. But I have not seen it in sailing yachts but now that I know, we may be able to check out the St Francis boat yard when we are in SA in April....
@@barefootdoctorssailing8567 tramp ladder with fold away center boards and rudder is a winning combination! beaching in the Bahamas is going to be spectacular fun, hope the next 2 years fly by, can not wait to see your new boat in action
Want to understand the sliding door location. Between the helm and weather deck not between the helm and cockpit? Sliding doors do not stow well for windage. On homes, french exterior doors can have the option to have a screen rolled vertically like a mast fuller. I wonder if rolling instead of sliding could work. Not sure, just an odd thought. I assume part of the storage under the helm would include a foot well for sheet/halyard tails. Protecting the instruments: I can not think of why like my quad controller you could not have a sun hood. More durable and made from aluminum with a black matte finish inside and a white gloss finish outside (rolled edges). It would help protect from water drops and make reading the instruments easier with fewer reflections (you could probably turn down the brightness lowing power consumption). :)
Unrelated: I have been thinking of solar panel placement on a boat we are considering. The best location based on shadows on a cat would be aft of the main cockpit roof. This of course has been done many times but I have not seen it with bifacial panels. The new bifacial panels are more efficient because the bottom layer is glass not opaque. Solar power is generated from not only the sun hitting the top surface but also reflected/refracted light striking the bottom of the panel. I can not think of a better application than collecting light bouncing off the water! The bifacial panel's pattern is attractive giving a filtered almost pergola quality of light/shade. I am with you... shade is important. Sorry for the unrelated tangent but I know you guys are considering more than the content of your videos.
As always no reply is expected. Know you are busy!!! Great progress guys.
Thanks again Boston!
It's a sliding door and yes there will be sacs for the sheets in the front section of the steering position floor (just not drawn in yet).
Thanks for the cover idea for the instruments and yes, as you say, the inside of the shade needs to be black....
Those new solar panels sound interesting too to get benefit from the direct and reflected light - I love that kind of double benefit!

7 to 10yrs WHAT, I can't wait that long, really??

Have a look at the design of the cockpit cover protection from the Xquisite X5 and Sixty
Thanks David, I certainly will do!!!
Oscar camera’s rock!
Yes amazing stuff, isn't it, Reinier!!!
Thanks for showing us this process - since we will be doing the same thing in 5 to 8 years it is very helpful. I’m interested to know how the payment structure works with the yard, are there milestones when you owe different amounts of the purchase price or do you pay all at once (start or end of construction?).
As for some ideas to consider on the design - have you considered instead of airtight voids to fill those voids with fire resistant and non-absorbent foam? You would get 90% of the floating power without the worry that the void would fill if compartment was punctured or had a failure. I think it would also probably reduce construction costs.
For insulation, Garcia has learned a lot from their years of experience building aluminum monohulls and they use a closed cell black foam against the bulkhead that helps not only insulate but also reduce the natural sweating that occurs from aluminum hulls.
Also from Garcia, for the outside steering station, did you consider the swinging helm that allows you to move yourself into the cockpit to steer in bad weather?
The engine rooms and walk around beds are great!
Any idea of the diesel capacity? If you want to be able to do things like the inside passage to Alaska, where sailing is often impractical, having a long fuel range would be nice. :)
Lots of good info, thanks Captain! I am not sure if all the boats are done the same but we have staged payments over the build time of the boat.
- Foam is a great idea but I thought that all foams were flammable so would add fuel to any fire - hopefully that is incorrect and it can be done.
- Diesel capacity is your choice cause the tanks are just built into the hulls.
- Garcias insulation is good (we have seen it) but it is significantly heavy. We are not planning to do the iceberg areas though - we don't like the cold!
- Yes many nice features in the design!
Thanks for the detailed comment and for following! Good luck on your path to your own boat...
Regards, Eli and John

Thanks Guys!
/I loved Dubai and miss all the weirdness, have been to the old souk at Dubai creek and been ushered into the secret rooms to look at the handbags, watches and sun glasses?? Rooms hidden behind bookshelves🤣🤣🤣. Move the winches outboard and bring the nav gear inboard, add a big eyebrow over the instruments, maybe incorporate a sliding coves that slides under the instrument cluster and you just place a cover over instruments to protect them😳😳
Hi again Nick, thanks for the suggestions. Yes currently we cover the instruments on the Leopard 45 but it would be so much easier if we can sort it with a hatch that slides across and keeps the rain and sun out of the aft cockpit at the same time...
Looking cool ...
For inspirational reading read about the round the Atlantic voyage of one of the first Windelo's using hybrid electric motor system ... Including heading to Newfoundland and Iceland .... Using a diesel generator back up and heating but solar and sail regen most of the time and occasional shore time plug in. Its a PDF if i remember.
Open steps going above the safety rails on the sides of the cabin im not sure of... my instincts and seeing a Bali cat with this means of bridge access tends to make me say no.
Re instruments what if they were mounted in either a drop down or pop up pod arrangement ?
Silent yatchs models have the whole thing in a fold down pod with a lower able roof for when helmed internally. 🤔⛵
Thanks Clive, interesting points. We have considered two electric engines and one diesel engine that acts as the generator and can power the boat but I still have concern about only one engine (motor or generator) because if it does, you can't motor or recharge batteries... You know the old saying about always having redundancy.... Big decisions ahead
@@barefootdoctorssailing8567
The electric motors are sound and usually trouble free the control electronics and interfaces are usually the source of troubles ...think of the fun you have when touch screens when wet🙄😬 or your fingers are dead to the screen.... One of my problems.
Greenline boats of Australia use
A Selectable propulsion system and so do Antares I think ..these systems can run either or but the compact nature and reliability of a Diesel generate electric system does save wt space and complexity.
Plus having a modular power train allows you to update the diesel generator motors and theres little or no need for any gearboxes or clutches.. to ware or maintain.
You can run for 4 hrs on a typical charged pack ..
The other thing is a the generators will improve in terms of size wt and efficiency with the use of more compact ICE motors that freed of direct drive and fluctuating revs and short inefficient run times will be more efficient and longer lived.
Two motors help you manoeuvre in close quarters ..tank turns.lol in silence
@@barefootdoctorssailing8567
The regen power under sail is often as much as the solar or the generators.
Heavy fuel fluid piston motors or rotary wankles APU units are tiny compared conventional generator motors.
The windelo had two generators on board ...one in back up but as they dont have to be in one place you can locate a generator remotely to suit your needs.
Fabulous update, guys‼️‼️ I'm wondering if Portafino would engage in the development and build of a 52-55' power catamaran??
Theres a English built Al powercat already being developed ...that might fit your brief as they are building to custom orders.
Dear Richard, I know that Raffaele has been approached by others wanting power cats so there is no reason not to ask him the question directly. It would require a different hull shape but the architects can sort that out.... Email him on Raffaele@portofinomarineservice.com or info @porto..... Good luck with your search!
Forgive my ignorance, but what safety/water ingress concerns might the aft doors to the cabin present? They look great! I’ve just noticed on following seas that a lot of water comes onto the aft platforms. Thanks.
Hi Jay and thanks for commenting again! Yes water does come up onto the aft transom but seldom as far forward as the door position. In extreme situations the door closes from the outside so any wave hitting it, forces it to seal tighter and it will be to a standard of a watertight hatch and not just a "door". Water hitting will also just drain away fast and not pool either.
As the wise man said, "We will see!!!"
Not sure if someone earlier suggested this but could the hard Bimini over the upper nav station be hydraulically lowered to provide a sealable cap in inclement Weather. It would also reduce windage and (if lockable) make it harder for someone to steal the boat.
I think your choice of aluminium and boatbuilders will give you many years of safe and comfortable sailing
Yes Gordon that is a really good idea and the other consideration was a rotating one but the lift up and down does sound cleaner to me... Thanks for the idea!
Happy to contribute in some small way
Great show today. Q, how do you plan to use the front stairs with the trampoline in the way?
HI Mason, the intention is to use it to access the water at the front of the boat for checking anchor and if we are nosed to the beach , we will use it to walk down.... The space that it takes is open but when the ladder is up the steps rotate to fill in the space so you won't fall through it.
Would there be any value in an onboard “muffle furnace” to dispose of organic garbage from food ? A muffle furnace reduces organic (food) matter to ashes, the ashes are compact, odor free and readily disposable.
Hi Tom, thanks for flooding and for the suggestion. Organic food matter on yachts is usually thrown overboard for the fish to eat and furnaces on boats have been used in the past but are a risk and presumably have to be built in in with chimney etc.... I have not heard of anyone doing it before now.
Just a thought, but why not have the “roof” over the helm station be the “hatch” that closes over the steering position. Would require hinging supports rather than the fixed stainless tubing/carbon struts?
Thanks for that great idea Alastair and we are certainly going to look into that possibility as several have suggested it too.
One observation/Question: In the video the welding appears to be "point-based" instead of a continuous double sided weld like what you see on "Distant Shores" new boat. Is this because it's an intermediate step before adding more welding or is it sufficient????
Hi Martin, thanks for watching and the comment. Yes that is to hold the AL in place before the final weld because the amount of heat that is produced in the full weld makes the AL warp if it is not spot welded first... Also see all those strips of AL on the outside of the boat - that is the same - to hold the AL in correct position while the main welds are done and to reduce movement of the sheets.
@@barefootdoctorssailing8567 TX - really interesting project and still cheaper than an HH or the likes. Looking forward to see how the boat is protected against corrosion.
I am not adventurous enough to take flight using a gianormous balloon. However, I would not mind taking a tour of Dubai. Amazing does not seem to cover it.
Hi Ray, yes Dubai is pretty amazing and completely man made! It was just empty desert before they had the courage to invest their money to create the city!
Hey John and Ellie, great episode again this week as usual. I also spent some time in Dubai and really enjoyed the Bedouin camp that you both went to. I really enjoyed the belly dancing, although I think I threw my back out just watching. I was interested in many of the features you discussed in your video this week. And I've been thinking at length about the ability to raise the centre boards and rudders - which is of course a great feature and necessary in many many parts of the world. However, whilst I realise that the centre boards will self raise upon hitting a solid object, I'm wondering have you considered if you hit a small reef, one only partially submerged - as opposed to high and dry rocks and a positive land strike - have you thought of having a rear anchor deployable off the stern, either on the main deck under the raisable platform between the two hulls with a winch to allow winching back onto the anchor, ie. OFF a reef - or perhaps two anchors, one in each sugar scoop with the commensurate winches? This would be advantageous when one or two hulls are perforated (seeing as you have watertight compartments), the boat could still be floated off or winched off, and then sailed to the nearest port for repairs. These would also be advantageous in various anchorages around the world, where one would like to be more confidant about ones anchored position in waters that maybe or are: choppy; confused, with eddies and currents; or beset with difficult windage. I know you asked for our thoughts and comments, and that mine add considerable expense to the exercise. But hey, just putting it out there. What expense peace of mind? Let me know what you think.
Fairwinds and following sees to the both of you. Don't get too excited yet it's still two years away. Cheers TB.
Thanks for the input Garth! Glad you enjoyed the balloon ride too! Yes we always use a stern anchor when beaching to reduce the sideways drift (protect the antifoul and paint) so we will have that and use the stern or the kite winches but have to launch it out manually. The Aluminium Fortress anchor is really good for that cause it is light and can be carried easily and launched from the dinghy if it can't be walked out.

Electric drive motor random thoughts: Instead of marine lithium batteries, could a Tesla solar Power-wall product work onboard a catamaran? Or like Caravan/RV campers have done, could you use 82 kWh Tesla flat battery pack(s) salvaged from scrapped cars to give you enough power storage at a reasonable price to consider an electric drive? Tesla car batteries might fit under your hull floor(s) in the airtight space.
Interesting ideas Michael. We are still wanting the electric engines to be good enough to run long enough with battery power and even large battery banks still only run for a very limited number of hours before needing to be recharged. So I see that as the biggest barrier as batteries are rapidly advancing with Sodium ones promising to be better than Lithium and other power cells being developed that hold even more power...
FYI RUclips Video of a DYI of Lagoon 45 with Tesla battery….

Love how you guys reveal your ongoing real life research
Will save everyone else a lot of shoe leather!
I have both an UV camera and a forward looking sonar. OSCAR uses Flir technology. I went with a Flir unit simply because of post-purchase serviceability anywhere. Sionyx is also good, I understand, but I have no experience with it. Forward looking sonar? I have B&G electronics so the B&G unit was an add-on. It seems to work well. However, the gold standard is Echopilot which is also somewhat expensive comparatively. But, you are spending USD1.5 million on a "dream" boat. Why would you not use the best?
Thanks Paddy - great details!!! So many decisions....
Just love a great police state! Everything is just so perfect. What’s the name of the union the workers building your boat are members of?
This is equally a question for boats made in china, Vietnam ect
Interesting comment, Gavin.The layout of the shipyard is 100% from the quality that Raffaele designs into his equipment and working areas, nothing to with anything outside the walls! I do not know anything about the politics but Dubai is a free market...
Will your engines be sail or shaft drive?
Hi Barry, definitely shaft drive - this allows DC generator to work, opens the possibility of regeneration and overcomes the drag and unreliability of sail drives...
Where will you taking delivery of you new catamaran?
Thanks for the question guys! We will pick her up in Dubai and depending on the timing sail to Maldives, Seychelles and back up the Red Sea to the Med and across the Atlantic...
@@barefootdoctorssailing8567 Where would you register it?
Will it not be possible to create a movable steering wheel like it is on the Balance? Regards from Germany
Thanks Thorsten. Yes we have considered that but as we have an internal steering position there is no need to steer from low down its aft cockpit. It may be useful though to have the closing hatch.... (Was that your point?)
I was also thinking along those lines with the movable steering. The helm can be shut out by a watertight door into the cockpit similar to the Sunreef one from the flybridge to the cockpit. Love the boat though...
Rain water may fall along the stairs (from helm Station) to salon (?)
Hi Claudio, yes that is why I want the hatch to close that space and also to keep sun out when it is hot...
@@barefootdoctorssailing8567 I made comment before seeing the rest of the video. If I remember correctly there is a video by Fountain Pajot that explains their solution to the problem (can't remember exactly, but a way to channel the water away
Hallo from Greece. First and foremost, i see the welding is not complete, minute 15:00 and 17:00. The welding quality is wery important with aluminum. Are there shaft drives? The helm is a compromise always. Balance cats has implemented the pivoting wheel very well. When thinking about protecting the steering station, i see everyone is thinking of something to pull down. something to pull up is also an option. "Windows" made of glass laying flat ahead of the instruments and on the left and behind the steerind position could seal very well. The right side could benefit from something that can be lifted up which may go down fast if needed. As for the instruments shade, video monitors have add on shades for outdoor use. Another idea is if the hole bimini could go down like a tripod with 4 legs or like a table with tripod legs.
Thanks for the suggestions Petros and the welding that yo use is not complete but only th initial spot welding to hold the pieces in place before the complete weld is done. If the whole weld is done first, my understanding is that the heat will course the metal to warp and the result is not good... Thanks for the other suggestions and we are looking at many of them to try and find practical solutions! Great info so thanks again!
Can you use the four-bar linkage with strut assists to raise and lower the whole cockpit roof? A weight savings as it acts as the both the door and roof. When it swings to the up position, a hinged visor could unfold from the roof top and lock into place for more forward sun protection. ruclips.net/user/shortsgaMdZ7oV6M0?feature=share
Interesting idea and we will need to look into how that works....
If there is some way this could be done to act as the cover for the space and the roof of th steering position, it would be great!!! I will pass this onto the designers..... Great lateral thinking!!! Thanks very much!
What about lightning protection

They probably use tiny electric motors to move the car dashboards..
Yes, that is being considered!
whats the weight of the cat
16T but the polars (VPPs) were calculated at 18T to allow for usual things on board.
Very interesting! You went over what design features the boat comes with, but you didn't go through any of the actual details of what you really get when it comes to what makes the boat sail for that base price:
1) Dacron Sails or performance laminate? Main and Jib, only or do you get any additional head sails?
2) How many winches? What brand, what Size? Electric or manual? I only see 2 in the video with no consideration for how to handle your code sails. What about clutches and line handling, it doesn't appear they've thought through this yet.
3) Mast - Aluminum or Carbon Fiber? Manufacturer?
4) Navigation/Electronics? What does it come with? One 9" Raymarine chart plotter or are you getting multiple plotters, MFD's and autopilot?
5) Radar?
6) Solar? How much, rigid or flexible? Is each panel have an individual controller for shading?
7) Refrigeration/freezers? How many, what size?
8) Watermaker? Brand/size?
9) How many kWh is the lithium battery bank?
10) Is the boat equipped with dual voltage 110/220 or do you have to choose?
11) Air Conditioning? How many units?
12) What engines come with the base price? Size/manufacturer.
13) Who is the manufacturer of this DC Generator? Are you talking about Integrel included in the base price
14) Electric toilets or hand pumpers?
15) Is all induction cooking part of the base price or extra?
16) Are there shades for all the windows in the saloon or is that extra?
17) Are all the cushions included in the forward cockpit and rear?
18) Is the Flexiteak flooring for the cockpit included or extra?
19) Underwater lighting included?
20) Is the full enclosure included or extra?
To just say the base boat costs $1.4M is a little misleading without explaining what you actually get for those dollars. It might be a fantastic value people should be running to place their deposits on, or it could be terrible value when compared to other boats currently available...sailing catamarans are such complex ecosystems with so many variables that without having the basic details above, it is impossible to tell if what you are buying is a good value or not. They appear to be making it up as they go along, which is great since you get to have your input, but a little scary as well if they haven't thought through the deck hardware yet of how you'll actually sail a performance boat. Cheers!
Hi again Kirk, thanks for such a detailed list of questions. However, if I went into that sort of detail with the options, 95% of the viewers would have shut it off in boredom and the video would be over an hour..... When we have actually decided ourselves on the options we will chose, we will make a full video about it. With all the brands, they give a ball park quote and some do make that cheap but you have to buy everything incl the anchor but for reference the inclusions are 4 pages and options are only 2 pages, so hopefully that gives you some idea.The price includes the essentials for sailing...
If anyone is seriously interested in the boat, they will get the spec sheets with the inclusions and options and judge it all for themselves.

HI JIm, yes thanks for that and the reversible seat backs are quite common in many brands incl both the two Leopards we have owned.
Can Portofino have a permanent device to prevent moisture in the boat ?
We have not got to discuss that yet but very interesting question - hopefully Raffaele can discuss the options for everyone to hear!
Following all the dreadful comment's on Leopard channel by your Aussie fellow sailors I reckon that loosing yours was a blessing in disguise the build quality of Leopard is so bad can't believe they are still in business.
Hi Ken, we went back and bought another Leopard and have had no trouble with it, all warranty issues and repairs approved easily with slow refunds but full refunds. If we are to trust our life to a major production cat brand on an ocean crossing, I would still trust the Leopards above ALL the other brands... We are moving to a performance boat as we miss those benefits and the shallow draft but we have no concerns with the Leopard yachts integrity.

Hi Mark, thanks for your concern but we were in the middle of colds and flus so maybe that showed through..
