George has a lovely vessel. If you see him again, be sure to let him know the fans appreciated his participation and complemented him on the fine work he has done to keep his vessel looking crisp.
Yeah agreed, the deck especially looked smashing. Nice bloke too "I yell as a rule!!" lol and very generous to allow his loud boat by way of comparison although I did like the old timers approach... a set of noise cancelling headphones!
I have watched Sailing Uma episodes from the beginning, and now, seeing this "sister ship," it really was like a walk back in time, particularly inside the cabin. What a sweet and satisfying reminder of all the work you've done it must be for you, especially on Uma's interior. She is really so well redesigned and updated now that she is actually like a brand new sailboat. You've done such great work in the redesign, and the workmanship in doing what you've done has been so craftsman-like. No, your workmanship has been nothing less than masterful. Huge kudos to you both. And now, the super quiet and efficient Ocean Volt motor that blended with the new sail drive is all but indicative of what you two have become together, a perfectly blended "power couple." What a team. Love you guys.
It looks like George has a well maintained boat, even if the interior is straight out of the Brady Bunch. Personally, I wouldn't care if the interior is dated or not, as long as it all functions as it's supposed to.
@@gmanwaseverywhere2104 You are so right about their work and everything they have done together. They are a joy to watch and do a great job explaining it all. To me the electric motor is awesome but id prefer the diesel, the range on a long sail across the pacific would be much better than sitting, hoping for wind. Yes the silance is nice, but? Enjoyed your well said post as well. Take care.
I wanted to give a shout-out regarding the great video and video editing in this step. Especially enjoyed how you incorporated the drone footage into the sea trial footage, how you filmed/edited putting the boat back in the water and the before/after, back/forth sound experienced comparison between the diesel and electric drive on the two different boats. All of this took a lot of effort in the editing room, was noticed, & was very appreciated.
Nicely done. Proprietary or not ... we'd love to see Oceanvolt's "autopsy" results on the old saildrive. If they explain their findings to y'all, please, do share!
Sending electricity through ball bearings is a particularly bad idea - the electrical arcing can erode the hardened ball bearings and their races, which promotes the rapid wearing of the bearing surfaces. This may be the cause of the awful crunchy noise in the sail drive.
@@bake162 That wouldn't explain why there was seawater inside the saildrive in the previous episode though. I suppose the lightning could have messed up the seal and welded the bearings/gears at the same time.
Hi there, it is so nice see you guys floating around Holland my birth country, I was born in Amsterdam in 1942 and we moved to South Africa in 1956, so I was 13 when we left. We visited Holland once in 1975 and traveled around the country for 5 weeks with our only daughter when she was 7 years old. Nice memories, have a great visit in Holland and I will be following you wherever you go!
So nice to see a mechanic using proper tools and doing a professional job. One thing you may want to keep in mind is that the closer each of the three propellers are to the exact same weight of each other, the less wobble or vibration, and the less wear on the bearings of the sail drive also. It may not seem like a big deal but it can really make all the difference in the long run.
At 26:26 & 26:31 I toggled between the two interior shots of the boats. The amount of space you have added while enhancing the show design is amazing. With two architectural degrees have you ever thought of eventually making some of this design work into a business? Your talents are super. Oceanvolt deserves BIG kudos for stepping up and helping you guys out with a defective "used" unit. That is so impressive. Happy Trails
I really like how Ocean Volt came out to help you figure out what was wrong and why it ran so loud. Impressive. It sounds really good now! You two did a fabulous job on your boat! Seeing the difference and how open and nice your boat is. It’s my dream boat too! 💕
It has been fascinating watching you two experiment & figure this stuff out. Thanks for all the work involved! Props to Oceanvolt for excellent support.
Wow so much quieter. Lol sounds like a denison of the deep softy but ominously calling to you beneath the boat at 7:00. Great company Ocean Volt to hear your troubles, send someone to investigate, and do you right by helping you get the drive unit fixed and back in the water. Now that is service! Beautiful footage of the local area too! Very cool sea trial. The OceanVolt is amazing. Great contrast with Georges's boat. Another excellent Sailing UMA video.
You, two wonderful people, are such ambassadors for the future of what sailing is all about. a few years from now people will wake up to the fact that it's not all about the schedule it's about being together for the moment in time.
You got a new sail drive with warranty and it is longer, which gives it better bite in the water and eliminates cavitation noise against the hull. That electric drive will likely produce more regeneration power due to the lower drag on the drivetrain. Well, all that worked out to your advantage! It was wonderful to see a sister ship to see the differences not only of the motoring configuration, but also the batteries, electrical, cabinetry, standing rigging, deck hardware, and the roominess. I’m sure you are quite pleased with your boat and of your accomplishments. Bravo Zulu!
Smart move by ocean volt to help you with a replacement and it's good to know it still worked with the damage! Enkhuizen and Hoorn are such Gems! Cheers Warren
This video demonstrates why I love your channel so much. There are many other sailing channels, but I get particular enjoyment from watching you work on your boat to constantly upgrade and fix it. It’s a much more realistic dream to fix up an old yacht than to sink half a million into a brand new one.
Ahh, the sweet sounds of smooth gearing! Lovely, entertaining content as ever. Uma and engineering, best place for a geek to come wind down. Thanks Dan & Kika.
The 🇳🇱 Netherlands...I was born there‼️ beautiful country and they love we Canadians ! You guys did a great job of quieting your boat down .....safe sailing 🇨🇦
Great episode. The electric motor has always been fascinating to me. I don't comment often, but thought I'd throw more kindness during this time considering some of the things you've posted on Instagram that just break my heart. Keep doing what you guys do! I think you're both amazing.
That was a treat for us technical nerds! You did the right thing going for the new saildrive. Now you have a reliable, modern drive with the regen option. Well done and so beautifully documented. And the comparison between identical boats was such a perfect coincidence, you couldn‘t have planned that any better. Kika and Dan, you let us take part in all the technical and design changes and to be able to see the original now I just have to say, your background as architects shows, the ship company can learn a lot from your interior design! Well done and thank you for sharing!
Their interior layout not only is done 50 years later then the original one, so using 50 more years of knowledge compared to the original designer, but mainly is a layout specific for the use they do of the boat, live aboard in only 2 people. The original design had a table on which more then 2 people can eat, had more berths, was a better design for short time cruising with more crew. They did a fantastic work on Uma's interior design, but it is not fair to compare it to the original one and if it is prefect for them would not be a great design for a production boat, as it is optimized to live aboard in 2 people, and it is not how the 99% of the boats are used for.
Saildrives are not exactly reliable or durable compared to shaft drive. Aluminum housings in Salt water are prone to failure. A spare drive would be a worthwhile thing to have.
I had a cal 31 and a Bayfield 26 both diesel powered when I lived in Victoria B.C. My favorite sound when sailing diesels is that magic moment after leaving the harbor when you shut down the engine and all you here is the wind passing by. great video.
That new saildrive sounds super smooth, I think getting a new one was the right choice. Excellent job. It is so fun to see a town I am familiar with through your eyes and to hear what you notice about it. I envy your electric setup, but one thing I do love is that moment when the sails are raised and you turn the engine off. That sudden silence and you are sailing is great. Thanks again for a great video :D
"Equipmake" make electic engines using lithium battery power for Race Cars , check em out for knowledge , they are in Norfolk UK I can see their technololgy fitting into direct drive situations similars to UMA but for all sizes .
Frankly, I wish someone would take it off my hands. I fell into another sailboat, an O'Day 37CC, that had already been updated to a Beta Marine. When given the option to go play on a boat or engine swap the Pearson, you know where I'll end up. The Pearson is far too beautiful to let sit around.
This is the old Navy Photographer PH2 USS TICONDEROGA I enjoy your presentations. Your knowledge that you have gained is incredible. Not a dull moment with you too. A lot of love there ❤ and you are full of fun but I know this is hard work I've done similar things in my day I just sold my 1978 VW WESTFALIA CAMPER that I spent over two yrs restoring. I did put two solar panels the thin flexible ones that produced 48 volts and I used the Victron charge controller i believe it was the the same one you showed on one of your videos. I was only using it to maintain the 3 batteries on board. I only went on one trip with it with my Navy shipmate and went from Florida to Seattle. Were both in our 60s and driving a VW without power steering for me was tuff because I have all worn out parts in my body. So keep doing what your doing while you're young.
Actually...the best reason is regen! They make 1kw at 6 knots and 3kw at 10 knots. If you had 2 of these, you could make more power than you would ever need!
Hi Dan and Kika. I might be your biggest non-sailing fan in the whole world. Very glado to see that you guys have managed to get the problem with your electric engene solved, very well done. Please let me know when you are in Hlland again, I would love to show you around a bit and give a bit back to you of the good time the you guys give to me here on RUclips. Stay safe and see you araound.
well IT'S ABOUT DANM TIME Ocean volt decided to get involved with your channel! I've been following you guys since the beginning, I remember you guys talked about them years ago and I was a bit disappointed that oceanvolt didn't decide to work with you sooner. But now that something's gone wrong with one of their units, they are slowly turning around having a glimpse of just how powerful your social media input is for their business. Hopefully they will take this as a lesson and will keep a long term partnership with you.
That's quite an entitled view point IMO. Of course if a company decides its worth while to get involved with a youtube channel and partner up as some form of advertising than they can, but it shouldn't be expected as a given which you seem to be implying (sorry If I'm reading this wrongly), Ocean Volt are already known as THE electric propulsion company for boats in the industry without needing extra advertisement and I say that as a long term Uma watcher. That said its nice that they decided to help out on this occasion, especially from the sound of it the fault wasn't down to a manufacturing defect.
@@ceirwan Well, if Oceanvolt only have about 400 systems delivered, they are not bigger than the other players, I´ve seen a fair few electric motor companies claiming 4-600 systems installed :)
given that they've only had their gear installed for a month or so and didn't buy it from the company, I doubt the company even knew they existed except for one of their Dutch tech reps who happened to follow their channel. And then invited them into his employer's wharf to check out their problems (the wharf they hauled out is the Dutch representative for Oceanvolt). I'd call that a pretty quick response.
And above all, what really matters, after all, it is that it’s not broken now, and you won’t be compromised by it any time soon. Safety wise it’s a great deal to count for. Cheers!!! Keep it up, best sailing videos, thanks!!
Wow! Great info you two. I've just decided HANDS DOWN to go electric (as soon as I save for, and find the boat of my dreams.......and refit it and, and......) Seems like lithium batteries and solar with an electric motor is the only way to go. You never have to buy fuel again. how liberating! Well done.
I did see a company doing hybrid systems. That seems like a pretty good way to go as well. Having a generator they can propel or charge as needed, while being likely mostly reliant on renewables.
Kika, admire your determination when it comes to stading for what is fair. We as human beings have forgotten limits when it comes to dignity and using UMA's platform to engage such a deep subject is remarcable.
I love your videos! Many young Canadian boys sacrificed their lives to liberate Holland in the spring of '45. The people of the Netherlands have never forgotten their sacrifice.
as an audiophile, your decision to go electric from the beginning makes this vlog so enjoyable to watch. So many tiny sounds that we can pick up and enjoy as you do what you do at that moment in time. it’s all in the details, including relevant sounds.
As a sailor currently without a boat your vlog is a constant inspiration and a pleasure to watch. Keep it up. It’s great. It’s also great to see two people who like each other and work well together. Thanks.
Great video... Interesting seeing a comparison between the 2 engines and seeing the new layout of Uma compared to the original layout. You both have come a long way in making your boat a home.
Been binge watching for a couple of weeks and finally got caught up. That was a shock in a way because I miss being able to just sit down and play another Uma episode whenever I want (often!). But it looks like I caught up just about the time you finished the rebuild. So now it really is Sailing Uma, instead of Rebuilding and Sailing Uma. You know you guys could easily consult on interior design and perhaps even write a book or do a series of videos (for patrons?) on the process of coming up with design strategies that increase liveability on boats. Also since you are on the cutting edge of electric propulsion, consulting and a book could easily be in the future if you so wish, especially now that you mostlly are done with projects and just need to do maintenance. When you talk, people who have any interest in electric propulsion listen!
World-wide logistics don't get enough credit or thanks. We can now move stuff like crazy. I'm not in the business but was in the Air Force's "UPS/Fed-Ex", Air Mobility Command and we moved equipment, parts and people 24/7 and kept track of every item. Glad that you noticed something wrong and took care of it promptly. You guys do rock! Uma looked naked out there sans sails.
Thank you for sharing your efficiency numbers. And, I'm glad you took a look at the saildrive. Better to catch it in a friendly port with good infrastructure than out in the boonies.
Sounds so smooth! And very interesting energy consumption results! Quite high actually. I got my electric conversion up and running few weeks ago to my 27ft boat. And these are the energy consumption with original prop: -1kn 100W -2kn 320W -3kn 700-800W -4kn 1kW+ -Full speed, 5,2kn, 3,3kW. These include the main contactor about 20W. This is actually very interesting and also gives overall idea of the energy needed for moving the boat even with sails! It has been very light winds so far so I haven't been able to test it in heavy winds or the ability to regen.
Hi guys, the first time I watched Sailing Uma was at the end of July (step 227), after that I binge-watched like a complete maniac to catch up and now I see that you stayed at my harbor (Compagnieshaven in Enkhuizen) and I missed the change to see Uma in real life :( :( Hope to get another change in the future, will defenitely keep watching, love your channel!
I'm new to your channel and I have to say I am absolutely in love with what you guys have done to Uma! So clean and minimal and that wood stove is just adorable.
Dan, I know you do not have time to watch Franny and our RUclips channel, especially when you may not have internet, but the two of you are so similar in how you think. You as an Architect and a handy person, are definitely an engineer at heart. Great handy work. I love watching people who like to figure things out. I like watching Kika getting her hands dirty too. You all are ahead of me. Heidi
You two have done a great and beautiful job restoring and refitting an old boat. Much to be said of "good bones". You have much to be proud of! Happy sailing!
Fun, fun, fun. Great city. Loved seeing the difference in the two boats. A big thank you to George. The noise tests from that app was sweet. Thx all. Happy travels.
Hi, definitely notice the change in noise from the drive system. Not just volume but it sounds ‘sweeter’, glad you got it sorted. It’s amazing to see Uma now, I remember when you first started refurbishing her. She’s ready for another 50 years at sea 👍👍👍😁😎.
I can’t help but say that you guys have this lifestyle down to a fine art!!! Your whole philosophy about life and the world totally reflects in the boat you have so carefully rebuilt over the years!! Your off grid self sufficient lifestyles intoxicating!!! Keep it up!!! Nanaimo guy here🇨🇦
Forgive me guys I've not commented in a while but this video shows what I've said to you a few times that you guys have come a mighty long way. I'm always happy to see when a new video drops to see what adventure you may be on. I get to see parts of the world because of it. Thanks for reaffirming my dreams. Live and grow well Kika and Dan, blessings to you always.
great review. That electric motor upgrade is a game changer. The company that makes that electric engine is luck to have you two showcasing it and promoting electric. The lower noise levels are a huge bonus but also consider the lower maintenance and the environmental benefits.
You guys are fantastic! I love this video and it makes sense to go electric, not just for the sound but also for maintenance and cost. Enjoy the peace!
It is such a treat to watch and learn from your journey. So cool also to join you on your friend's George's boat and go back down memory lane from what you had done to your boat. I hope you get many years of quite operation from your new sail drive. Thank you for bringing us along and sharing your voyages and lessons.
Great Video guys 👍🏼 The difference between electric and diesel is range, diesel 2 days @5knots, the electric 3hrs/day for unlimited days @5knots. The more I watch your channel the more i'm convinced that electric will be the way to go for my next boat, i've never run a diesel or outboard on a boat for more than 1 hour per day, but I have sailed on and off my mooring because I couldn't be bothered to start the motor.
Not sure if you motor 3 hours, how many time it take to recharge using solar (assuming no wind for regen because you want to motor) in order to get another 3 hour run. Let's say you can motor a day on two ?
I agree with Romain - Uma has an awesome setup but saying "electric 3hrs/day for unlimited days @5knots" is a misrepresentation that could be accepted as fact by those who don't understand recharge rates and all the variables related to it. I don't remember the size of their battery bank and the size of their solar array but they did mention the recharge rate from the prop at certain hull speeds. I think under ideal conditions (full sun and decent sailing speed for prop regen) theoretically, they can come close to fully recharging their batteries in a 24 hour cycle but how many 24 hour cycles out at sea are under these particular ideal conditions? Much fewer than 50%. Here is my very rough calculation showing how I arrived at my estimate. Assumptions: 1. 3 hrs at 5 knots drains battery bank. 2. Battery Bank is 12 Battle Born 100 amp 12 volt batteries = 14,400 watts. 3. 1,000 watts of solar array 5 hrs/day at 1,000 watts + 4 hrs/day at 500 watts + 3 hrs/day at 250 watts = 7,750 watts. Sail drive regen. average 24 hrs at 300 watts/hr = 7,200 watts. Actual watts produced from solar and regen (7,500 + 7,200 = 14,700) x .85 efficiency = 12,500. This very optimistic number 12,500 gets you charged up to 85% of the 14,400 watt battery capacity assuming you used 0 watts of your battery bank for running all systems, electronics, cooking, water heating, refrigeration, laptops etc... In REAL sailing conditions, if you used the motor for 3 hrs depleting the battery, you might generate enough power in the next 24 hours to get the battery bank half full again for 1 hour of motoring plus other electrical demands and that number is probably closer to the maximum "unlimited" days of propulsion for 1 hour, if lucky. Draining ones battery bank frequently will significantly reduce the performance and life of the battery bank even with Lithium chemistry. The Uma crew are real sailors and only use mechanical propulsion for short periods of time so this setup the way they use it does provide them with "unlimited" mechanical propulsion. To get them unlimited 3 hrs/day propulsion they would need to tow a barge behind Uma loaded with Lithium batteries covered by a roof of solar panels.
You don't always have to go 5kts though. Slowing to 4kts might let you go for 6 or 8 hours a day, and at 3kts, you would be able to motor a lot longer than that. You plan your trip for the available energy, and when you get there, you can anchor and recharge for free.
@MrGunboat78 Yes, that is the "best" setup for now for both safety and meeting a schedule. Depending on "fuel" from the sun for solar, wind for a top side wind generator and thus bottom side prop regenerator while sailing (due to wind) are fickle. One must overcompensate for these undependable power sources by carrying extra weight in provisions, batteries, water, medical equipment, etc... OR like you, a dependable diesel GenSet with enough fuel to complete your mission under the worse conditions in the time you have allotted. The Uma crew is young, in good health with no deadlines and a well provisioned boat. They figured out what works for them and I love that they are helping to push forward, by example this technology. It is important however not to oversell or over represent the current practical application of this technology. I don't believe they are doing this but others may be misinterpreting their capabilities and setting an unrealistic expectation for those in the planning stages of having an all electric boat.
@@brianorca No doubt brianocra a sailor can make this system work for them with good weather predictions of fuel replenishment in the form of sun and wind. Weather prediction is so much better now than it was 10 years ago but it still has a long way to go. If you have some flexibility regarding passage durations and you bring extra provisions "just in case" and you have an adventurer's attitude that deals well with uncertainty....you are golden. The Uma setup would work fine for me.
Definitely worth the revisit after watching Show 222. I had forgotten about the 1972 Person 36 comparison between your boat and George's boat. The decking on his boat was nice. Have a Magical Day!
Just discovered your channel on the advice of other cruisers. We have a 86 Bristol 41.1 Same company different name. Sure would like an electric drive, diesel is so yesterday.
Congratulations to both of you. An old geezer in Argentina quarantine keeping relatively sane by watching things on RUclips. Your posts are way among the very best. Particularly like Dan´s expert mods and repairs and Kika´s bubbly character. Thank you. Saludos y buena suerte.
Really interesting, I liked being able to see the difference, I really love your boat by the way, all the refits are amazing compared to what it was on his, I did like his vinyl matting on his, how's it compare to your repaint texture on the deck? The other thing I think is important, he may have more range with the diesel, but you are OFF-GRID, so you NEVER have to refuel or do as much maintenance, saving tons of money.
I am wondering if you intend to convert to lithium - carbon batteries from lead - acid to complement your electric engine and drive system, adding new (if necessary), highly efficient solar panels which recently have become available? The "Sailing Brick House" channel has Rebecca's excellent exposition on implementing such a conversion. So to does the "Ran" channel (he seems masterfully handy at doing this conversion). The reasons to do so seem overwhelmingly compelling in numerous regards now that the technology appears non-susceptible to fire (a lithium - ion battery problem now surpassed by lithium - carbon technological advsncements, less heavy by half, less room consuming, etc. advantages. I am super enamored of your electric motor and was keenly interested by your having had it for 6 years - has it ever given you folks any trouble particularly from lightning. If you've had that experience? Denver, Colorado
It's lovely to see you guys sail on familiar territory (IJsselmeer, Markermeer). I've sailed there with my friends, admittedly on a motorboat. Visiting these old towns is a big part of the fun. Love your blog, keep up the good work.

My guess is the lightning strike compromised a seal and let seawater in which corroded the gears and bearings.
My guess would be the lightning welded the bearings or gears starting the damage
Sending electricity through ball bearings is a particularly bad idea - the electrical arcing can erode the hardened ball bearings and their races, which promotes the rapid wearing of the bearing surfaces. This may be the cause of the awful crunchy noise in the sail drive.
Im sure it didnt help

Can you give us a quick update in a future vlog about what the teardown found was wrong once OceanVolt has it apart? Don't leave us hanging.
So nice to see a mechanic using proper tools and doing a professional job. One thing you may want to keep in mind is that the closer each of the three propellers are to the exact same weight of each other, the less wobble or vibration, and the less wear on the bearings of the sail drive also. It may not seem like a big deal but it can really make all the difference in the long run.
I love Uma, but the color scheme on his Pearson is really sharp!

You, two wonderful people, are such ambassadors for the future of what sailing is all about. a few years from now people will wake up to the fact that it's not all about the schedule it's about being together for the moment in time.

I’m sure you are quite pleased with your boat and of your accomplishments. Bravo Zulu!
10:50 Uma looks absolutely immaculate, you guys have done such a good job with her. Pure class.
I'm failing to understand why people would dislike this video. Your content is interesting. Well done and thank you.
Another advantage of electric is the lack of Diesel engine smell. Thanks for the thoroughness of your comparison. Really liked the video.
I can’t help but laugh each time I see these two. Love you both!
Smart move by ocean volt to help you with a replacement and it's good to know it still worked with the damage!
Enkhuizen and Hoorn are such Gems!
Cheers Warren
This video demonstrates why I love your channel so much. There are many other sailing channels, but I get particular enjoyment from watching you work on your boat to constantly upgrade and fix it. It’s a much more realistic dream to fix up an old yacht than to sink half a million into a brand new one.
Ahh, the sweet sounds of smooth gearing! Lovely, entertaining content as ever. Uma and engineering, best place for a geek to come wind down. Thanks Dan & Kika.
The 🇳🇱 Netherlands...I was born there‼️ beautiful country and they love we Canadians ! You guys did a great job of quieting your boat down .....safe sailing 🇨🇦
Great episode. The electric motor has always been fascinating to me. I don't comment often, but thought I'd throw more kindness during this time considering some of the things you've posted on Instagram that just break my heart. Keep doing what you guys do! I think you're both amazing.
The Oceanvolt sales engineer and the company in general went above and beyond. And deserve a LOUD shoutout.
That was a treat for us technical nerds! You did the right thing going for the new saildrive. Now you have a reliable, modern drive with the regen option. Well done and so beautifully documented.
And the comparison between identical boats was such a perfect coincidence, you couldn‘t have planned that any better.
Kika and Dan, you let us take part in all the technical and design changes and to be able to see the original now I just have to say, your background as architects shows, the ship company can learn a lot from your interior design! Well done and thank you for sharing!
Their interior layout not only is done 50 years later then the original one, so using 50 more years of knowledge compared to the original designer, but mainly is a layout specific for the use they do of the boat, live aboard in only 2 people.
The original design had a table on which more then 2 people can eat, had more berths, was a better design for short time cruising with more crew.
They did a fantastic work on Uma's interior design, but it is not fair to compare it to the original one and if it is prefect for them would not be a great design for a production boat, as it is optimized to live aboard in 2 people, and it is not how the 99% of the boats are used for.
@@andreachinaglia5804 Just painting walls and trim in white is by itself a huge improvement over the dark paneling ! Plus LEDs everywhere !
Saildrives are not exactly reliable or durable compared to shaft drive. Aluminum housings in Salt water are prone to failure. A spare drive would be a worthwhile thing to have.
I had a cal 31 and a Bayfield 26 both diesel powered when I lived in Victoria B.C. My favorite sound when sailing diesels is that magic moment after leaving the harbor when you shut down the engine and all you here is the wind passing by. great video.
That new saildrive sounds super smooth, I think getting a new one was the right choice. Excellent job. It is so fun to see a town I am familiar with through your eyes and to hear what you notice about it.
I envy your electric setup, but one thing I do love is that moment when the sails are raised and you turn the engine off. That sudden silence and you are sailing is great.
Thanks again for a great video :D
"Equipmake" make electic engines using lithium battery power for Race Cars , check em out for knowledge , they are in Norfolk UK
I can see their technololgy fitting into direct drive situations similars to UMA but for all sizes .
Great job and huge props to Oceanvolt! Nice to see you standing behind your product and helping out when people are in trouble.
I've got a 1973 Pearson 36 that I keep threatening to put an electric motor in, you guys have done a great job.
Frankly, I wish someone would take it off my hands. I fell into another sailboat, an O'Day 37CC, that had already been updated to a Beta Marine. When given the option to go play on a boat or engine swap the Pearson, you know where I'll end up. The Pearson is far too beautiful to let sit around.
@@EvanMJones I"ll take it off your hands! Where is it?
This channel is dangerous for you (and people likely to ask to buy your boat)
This is the old Navy Photographer PH2 USS TICONDEROGA I enjoy your presentations. Your knowledge that you have gained is incredible. Not a dull moment with you too. A lot of love there ❤ and you are full of fun but I know this is hard work I've done similar things in my day I just sold my 1978 VW WESTFALIA CAMPER that I spent over two yrs restoring. I did put two solar panels the thin flexible ones that produced 48 volts and I used the Victron charge controller i believe it was the the same one you showed on one of your videos. I was only using it to maintain the 3 batteries on board. I only went on one trip with it with my Navy shipmate and went from Florida to Seattle. Were both in our 60s and driving a VW without power steering for me was tuff because I have all worn out parts in my body. So keep doing what your doing while you're young.
I love all the problem-solving and diagnosing. And your general mission in life. Thanks.
Great audio and data comparisons of both versions of the same boat. Annette says, "oh those are Kika size roads". lol. Take care guys.
20:21 George has an ultrasonic dish washer. ; )
Davis S: wonderful! Knew there had to be an advantage for diesel power!🤪
Great comparison, and glad you got her repaired. Awesome video.
No diesel fumes is the best reason. You get to smell the fresh ocean to the max.
Actually...the best reason is regen!
They make 1kw at 6 knots and 3kw at 10 knots. If you had 2 of these, you could make more power than you would ever need!
No diesel NOISE too! Terrible.
Hi Dan and Kika. I might be your biggest non-sailing fan in the whole world.
Very glado to see that you guys have managed to get the problem with your electric engene solved, very well done.
Please let me know when you are in Hlland again, I would love to show you around a bit and give a bit back to you of the good time the you guys give to me here on RUclips.
Stay safe and see you araound.
well IT'S ABOUT DANM TIME Ocean volt decided to get involved with your channel! I've been following you guys since the beginning, I remember you guys talked about them years ago and I was a bit disappointed that oceanvolt didn't decide to work with you sooner. But now that something's gone wrong with one of their units, they are slowly turning around having a glimpse of just how powerful your social media input is for their business. Hopefully they will take this as a lesson and will keep a long term partnership with you.
Yup, these channels are like an entire marketing department.
Help the tubers, get a million eyes on your products.
That's quite an entitled view point IMO.
Of course if a company decides its worth while to get involved with a youtube channel and partner up as some form of advertising than they can, but it shouldn't be expected as a given which you seem to be implying (sorry If I'm reading this wrongly), Ocean Volt are already known as THE electric propulsion company for boats in the industry without needing extra advertisement and I say that as a long term Uma watcher.
That said its nice that they decided to help out on this occasion, especially from the sound of it the fault wasn't down to a manufacturing defect.
@@ceirwan Well, if Oceanvolt only have about 400 systems delivered, they are not bigger than the other players, I´ve seen a fair few electric motor companies claiming 4-600 systems installed :)
@@Robinlarsson83 You wrote "Well, if Oceanvolt only ..."
To "if" or not "if", that is the question.
given that they've only had their gear installed for a month or so and didn't buy it from the company, I doubt the company even knew they existed except for one of their Dutch tech reps who happened to follow their channel.
And then invited them into his employer's wharf to check out their problems (the wharf they hauled out is the Dutch representative for Oceanvolt).
I'd call that a pretty quick response.
And above all, what really matters, after all, it is that it’s not broken now, and you won’t be compromised by it any time soon. Safety wise it’s a great deal to count for. Cheers!!! Keep it up, best sailing videos, thanks!!
Wow! Great info you two. I've just decided HANDS DOWN to go electric (as soon as I save for, and find the boat of my dreams.......and refit it and, and......) Seems like lithium batteries and solar with an electric motor is the only way to go. You never have to buy fuel again. how liberating! Well done.
I did see a company doing hybrid systems. That seems like a pretty good way to go as well. Having a generator they can propel or charge as needed, while being likely mostly reliant on renewables.
Kika, admire your determination when it comes to stading for what is fair. We as human beings have forgotten limits when it comes to dignity and using UMA's platform to engage such a deep subject is remarcable.
You two just keep getting better at content, editing, and production. Thank you for sharing your adventures.
Glad to hear Uma is fixed and doing great! Love what you two have done to the interior of her.
Fair seas and good winds to you!!
I love your videos! Many young Canadian boys sacrificed their lives to liberate Holland in the spring of '45. The people of the Netherlands have never forgotten their sacrifice.
as an audiophile, your decision to go electric from the beginning makes this vlog so enjoyable to watch. So many tiny sounds that we can pick up and enjoy as you do what you do at that moment in time. it’s all in the details, including relevant sounds.
Uma looks great and with your technical/electronic upgrades and interior remoddeling it looks even modern, nut nothing beats a teak deck on a boat.
As a sailor currently without a boat your vlog is a constant inspiration and a pleasure to watch. Keep it up. It’s great. It’s also great to see two people who like each other and work well together. Thanks.
Great video... Interesting seeing a comparison between the 2 engines and seeing the new layout of Uma compared to the original layout. You both have come a long way in making your boat a home.
Been binge watching for a couple of weeks and finally got caught up. That was a shock in a way because I miss being able to just sit down and play another Uma episode whenever I want (often!). But it looks like I caught up just about the time you finished the rebuild.
So now it really is Sailing Uma, instead of Rebuilding and Sailing Uma.
You know you guys could easily consult on interior design and perhaps even write a book or do a series of videos (for patrons?) on the process of coming up with design strategies that increase liveability on boats.
Also since you are on the cutting edge of electric propulsion, consulting and a book could easily be in the future if you so wish, especially now that you mostlly are done with projects and just need to do maintenance. When you talk, people who have any interest in electric propulsion listen!
OMGoodness, I'm so glad you mentioned, then fixed the focus - I thought I was going blind!
World-wide logistics don't get enough credit or thanks. We can now move stuff like crazy. I'm not in the business but was in the Air Force's "UPS/Fed-Ex", Air Mobility Command and we moved equipment, parts and people 24/7 and kept track of every item. Glad that you noticed something wrong and took care of it promptly. You guys do rock! Uma looked naked out there sans sails.
Thank you for sharing your efficiency numbers. And, I'm glad you took a look at the saildrive. Better to catch it in a friendly port with good infrastructure than out in the boonies.
Now we are talking. Lot better and more efficient. Good you two found help with the sail drive. Cheers!
Sounds so smooth! And very interesting energy consumption results! Quite high actually.
I got my electric conversion up and running few weeks ago to my 27ft boat. And these are the energy consumption with original prop:
-1kn 100W
-2kn 320W
-3kn 700-800W
-4kn 1kW+
-Full speed, 5,2kn, 3,3kW.
These include the main contactor about 20W.
This is actually very interesting and also gives overall idea of the energy needed for moving the boat even with sails! It has been very light winds so far so I haven't been able to test it in heavy winds or the ability to regen.
Hi guys, the first time I watched Sailing Uma was at the end of July (step 227), after that I binge-watched like a complete maniac to catch up and now I see that you stayed at my harbor (Compagnieshaven in Enkhuizen) and I missed the change to see Uma in real life :( :( Hope to get another change in the future, will defenitely keep watching, love your channel!
Your boat is my dream boat too. It is so inspirational to see 2 hardworking people and what can be achieved :)
So nice to have this problem resolved. Loved seeing the sister boat. Blue hull was really nice.
I'm new to your channel and I have to say I am absolutely in love with what you guys have done to Uma! So clean and minimal and that wood stove is just adorable.
Dan, I know you do not have time to watch Franny and our RUclips channel, especially when you may not have internet, but the two of you are so similar in how you think. You as an Architect and a handy person, are definitely an engineer at heart. Great handy work. I love watching people who like to figure things out. I like watching Kika getting her hands dirty too. You all are ahead of me. Heidi
You two have done a great and beautiful job restoring and refitting an old boat. Much to be said of "good bones". You have much to be proud of! Happy sailing!
This youtube channel has inspired me to pick up sailing as hobby. Love the content so far 😍 especially the technical and nerdy contents
Welcome in the same boat ...
- which is a Danish idiom that means "we do the same thing"
Fun, fun, fun. Great city. Loved seeing the difference in the two boats. A big thank you to George. The noise tests from that app was sweet. Thx all. Happy travels.
Man you build this boat like a champion, love every thing you did guys 🛥️👍🤜
Hi, definitely notice the change in noise from the drive system. Not just volume but it sounds ‘sweeter’, glad you got it sorted. It’s amazing to see Uma now, I remember when you first started refurbishing her. She’s ready for another 50 years at sea 👍👍👍😁😎.
The filming and editing are so good its just beautiful.
I can’t help but say that you guys have this lifestyle down to a fine art!!! Your whole philosophy about life and the world totally reflects in the boat you have so carefully rebuilt over the years!! Your off grid self sufficient lifestyles intoxicating!!! Keep it up!!! Nanaimo guy here🇨🇦
Love the calmness of the editing and sound mixing! Great job!
OMG, I started watching at maybe like step 200'ish and I just hit the binge button and saw step 1, you guys look like little kids! : )
You guys are such a beautiful couple love watching your videos such a inspiration
Forgive me guys I've not commented in a while but this video shows what I've said to you a few times that you guys have come a mighty long way. I'm always happy to see when a new video drops to see what adventure you may be on. I get to see parts of the world because of it. Thanks for reaffirming my dreams. Live and grow well Kika and Dan, blessings to you always.
Thank you so much guys😄😄😄✌✌✌💓💓💓
Glad to get some closure after last week’s cliffhanger! The engine/drive definitely sounds much better!
Great catch of the Carillon (bell tower).
Agree with others that I'd love to see the inside of that saildrive
New sail drive "sounds" great. Love that you boosted your efficiency as well! Awesome episode guys! Fair winds and following seas Uma!!
great review. That electric motor upgrade is a game changer. The company that makes that electric engine is luck to have you two showcasing it and promoting electric. The lower noise levels are a huge bonus but also consider the lower maintenance and the environmental benefits.
You’re the cutest couple. Enjoy your venture
great vid, with all the figures. Plus it is valuable to know the drawbacks aswell. So that vid was very educational, thanks a lot.
This video was epic! I’d been waiting for the outcome to the sail drive and the videography delivered 👌
Pretty nice of the company to go out of their way to help y'all out. The new engine is impressive!!!!
Just watched your interview with Ruby rose on electric motor, it comes together with this one. Good job folks !
Love George’s choice of Pants, those old BDU pants are so comfortable! I really wish a clothing company could make pants that good and comfy.
Yeah, Semper Fi to George if he's a Marine.
What a lovely town.
You guys are fantastic! I love this video and it makes sense to go electric, not just for the sound but also for maintenance and cost. Enjoy the peace!
Hi guys, great video. I love that you did an anallytical approach to the whole electronic vs diesel. BTW the focus problem was due to your hair...😉
haha 😂silly hair, always getting all the attention.
It is such a treat to watch and learn from your journey. So cool also to join you on your friend's George's boat and go back down memory lane from what you had done to your boat. I hope you get many years of quite operation from your new sail drive. Thank you for bringing us along and sharing your voyages and lessons.
Great Video guys 👍🏼
The difference between electric and diesel is range, diesel 2 days @5knots, the electric 3hrs/day for unlimited days @5knots.
The more I watch your channel the more i'm convinced that electric will be the way to go for my next boat, i've never run a diesel or outboard on a boat for more than 1 hour per day, but I have sailed on and off my mooring because I couldn't be bothered to start the motor.
Not sure if you motor 3 hours, how many time it take to recharge using solar (assuming no wind for regen because you want to motor) in order to get another 3 hour run.
Let's say you can motor a day on two ?
I agree with Romain - Uma has an awesome setup but saying "electric 3hrs/day for unlimited days @5knots" is a misrepresentation that could be accepted as fact by those who don't understand recharge rates and all the variables related to it. I don't remember the size of their battery bank and the size of their solar array but they did mention the recharge rate from the prop at certain hull speeds. I think under ideal conditions (full sun and decent sailing speed for prop regen) theoretically, they can come close to fully recharging their batteries in a 24 hour cycle but how many 24 hour cycles out at sea are under these particular ideal conditions? Much fewer than 50%. Here is my very rough calculation showing how I arrived at my estimate. Assumptions: 1. 3 hrs at 5 knots drains battery bank. 2. Battery Bank is 12 Battle Born 100 amp 12 volt batteries = 14,400 watts. 3. 1,000 watts of solar array 5 hrs/day at 1,000 watts + 4 hrs/day at 500 watts + 3 hrs/day at 250 watts = 7,750 watts. Sail drive regen. average 24 hrs at 300 watts/hr = 7,200 watts. Actual watts produced from solar and regen (7,500 + 7,200 = 14,700) x .85 efficiency = 12,500. This very optimistic number 12,500 gets you charged up to 85% of the 14,400 watt battery capacity assuming you used 0 watts of your battery bank for running all systems, electronics, cooking, water heating, refrigeration, laptops etc... In REAL sailing conditions, if you used the motor for 3 hrs depleting the battery, you might generate enough power in the next 24 hours to get the battery bank half full again for 1 hour of motoring plus other electrical demands and that number is probably closer to the maximum "unlimited" days of propulsion for 1 hour, if lucky. Draining ones battery bank frequently will significantly reduce the performance and life of the battery bank even with Lithium chemistry. The Uma crew are real sailors and only use mechanical propulsion for short periods of time so this setup the way they use it does provide them with "unlimited" mechanical propulsion. To get them unlimited 3 hrs/day propulsion they would need to tow a barge behind Uma loaded with Lithium batteries covered by a roof of solar panels.
You don't always have to go 5kts though. Slowing to 4kts might let you go for 6 or 8 hours a day, and at 3kts, you would be able to motor a lot longer than that. You plan your trip for the available energy, and when you get there, you can anchor and recharge for free.
@MrGunboat78 Yes, that is the "best" setup for now for both safety and meeting a schedule. Depending on "fuel" from the sun for solar, wind for a top side wind generator and thus bottom side prop regenerator while sailing (due to wind) are fickle. One must overcompensate for these undependable power sources by carrying extra weight in provisions, batteries, water, medical equipment, etc... OR like you, a dependable diesel GenSet with enough fuel to complete your mission under the worse conditions in the time you have allotted. The Uma crew is young, in good health with no deadlines and a well provisioned boat. They figured out what works for them and I love that they are helping to push forward, by example this technology. It is important however not to oversell or over represent the current practical application of this technology. I don't believe they are doing this but others may be misinterpreting their capabilities and setting an unrealistic expectation for those in the planning stages of having an all electric boat.
@@brianorca No doubt brianocra a sailor can make this system work for them with good weather predictions of fuel replenishment in the form of sun and wind. Weather prediction is so much better now than it was 10 years ago but it still has a long way to go. If you have some flexibility regarding passage durations and you bring extra provisions "just in case" and you have an adventurer's attitude that deals well with uncertainty....you are golden. The Uma setup would work fine for me.
Definitely worth the revisit after watching Show 222. I had forgotten about the 1972 Person 36 comparison between your boat and George's boat. The decking on his boat was nice. Have a Magical Day!
had to stop watching at 3:07 and comment. From Kiki, "By the way, there's a brewery".......LOL
What a good gal....
Keeper
I miss living in Holland, thank you for the love, bringing the sounds and sights, it was awesome.
Interesting test. Enjoyed the walk through.
Wasn't expecting to run in to you here, I'll return to your channel shortly.
What a great couple. The energy is just right!!! You guys are hyped to an unrealistic level .... But yea pretty cool!!!
Just discovered your channel on the advice of other cruisers. We have a 86 Bristol 41.1 Same company different name. Sure would like an electric drive, diesel is so yesterday.
It's so cool that you have the first Tesla of boats! Love it.
damn infernal combustion engines!
thnx for another dandy episode.
Got it, thanks guys...dont know how I missed that one...
Ooh, I do like the look of his boat though! Blue hulls are 😍
I think so too!
Congratulations to both of you. An old geezer in Argentina quarantine keeping relatively sane by watching things on RUclips. Your posts are way among the very best. Particularly like Dan´s expert mods and repairs and Kika´s bubbly character. Thank you. Saludos y buena suerte.
Really interesting, I liked being able to see the difference, I really love your boat by the way, all the refits are amazing compared to what it was on his, I did like his vinyl matting on his, how's it compare to your repaint texture on the deck? The other thing I think is important, he may have more range with the diesel, but you are OFF-GRID, so you NEVER have to refuel or do as much maintenance, saving tons of money.
I am wondering if you intend to convert to lithium - carbon batteries from lead - acid to complement your electric engine and drive system, adding new (if necessary), highly efficient solar panels which recently have become available? The "Sailing Brick House" channel has Rebecca's excellent exposition on implementing such a conversion. So to does the "Ran" channel (he seems masterfully handy at doing this conversion). The reasons to do so seem overwhelmingly compelling in numerous regards now that the technology appears non-susceptible to fire (a lithium - ion battery problem now surpassed by lithium - carbon technological advsncements, less heavy by half, less room consuming, etc. advantages.
I am super enamored of your electric motor and was keenly interested by your having had it for 6 years - has it ever given you folks any trouble particularly from lightning. If you've had that experience?
Denver, Colorado
It's lovely to see you guys sail on familiar territory (IJsselmeer, Markermeer).
I've sailed there with my friends, admittedly on a motorboat.
Visiting these old towns is a big part of the fun.
Love your blog, keep up the good work.
