So informative. This should be a Nat Geo or Discovery Channel series. Remember when they ran stuff like this? I wouldn't miss an episode. The engineering, science, and real life experience is amazing. I hope some teachers are out there showing material like this to their kids.
I have a 1996 Carver 440. LOA is about 48'. I learned how to surf my boat when I took it from TX to FL in the Gulf. I never knew surfing boats was a thing until I accidentally did it. I was seeing 22kts with the throttles set to sustain about 13kts. Cool video!
I have had some great experiences surfing my 44’ catamaran downwind in big seas and wind. I have to agree that it can be more comfortable once you get used to the concept. Hitting 22 knots is always going to feel good!
I'm guessing the purpose of this vessel (FPB 78-1 Cochise) is to travel around the world? To accomplish this there seems to be a lot of unusual (to me) devices around the boat, especially the purpose of the bow rack (camera stand plus?). Please, what video(s) gives detailed description(s) of the Cochise design and systems (Sea Trials)? ;-)
In smooth water, calm conditions, at ten knots FPB 78-1 will burn about six gallons an hour. So, at 15kph, she consumes about 22.7liters per hour, or about 1.51 liters per kilometer.
@@DashewOffshore thats what I said, so 150Liters per 100KM.....that is actually very scary....and unbelieveable....say for the car industry..... forced to reach below 100mg CO2 per 100KM in their produced fleet, which resembles like !!!4!!! Liter Diesel per 100KM......and even....150Liter Diesel we dare to call these days a super efficient yacht. This all sucks.
When l worked in the fishing industry, crayfisherman would fly over to Australia, purchase a big glass or alloy cray oat and surf them back to nz 30 yrs back
Truly amazing🇨🇦 🤘😎🤘 🇨🇦 refreshing to find out that faster is better Please keep the videos coming would be nice to see a video blog from stocking the boat for departure and eventually arrival in paradise
As a layman its hard for me to get the perspective of the surfing. I understand it, its just hard to see up close. I think if you invested in a camera drone you could figure it out. A birds eye view would give the further away view and make it easy to see what the boat is doing.
I'm at 6:31. Why would you not go for a lifting(planing) hull? Seems to me Surfing is a close second to planing? Having done both sometimes at the same time in laser 4000 and seen the speed improvements. Surfing requires much more helm whereas planing in a well balanced boat is stable. Where is the advantage of a keelboat that can't plane but can surf. My Dad had a squib that could surf but not plain and I Don't get the point of that if the hull is stable. Is it a compromise for space to make the a planing hull? Luv and Peace.
The same thought occurred to me, but this is my understanding of their concept. I think their concern with a planing hull in those conditions is that it will plane down the face of the wave and stuff the bow in the back of the wave ahead, causing extreme bow steering. I believe they are using the suction in the aft portions of the hull to trim the bow out of the water and to create enough drag to keep the boat high on the face of the waves. A planing hull in those conditions would take active steering and throttle control, so they opted for a design that is more self regulating. I recommend you read The Naval Architecture Of Planing Hulls by Lindsay Lord. Lord discusses some of the issues of Bluewater planing hulls. Remember that when sailing dinghies and skiffs we can move the center of mass aft considerably to keep the bow out of the water which massively helps reduce helm caused by the hull form. You can see the challenges of large Bluewater planing hulls when you watch video of VOR65s or non foiling IMOCAs. They work very hard steering those boats to keep the bow out of the water. A well designed semi-displacement hull can have very neutral helm above hull speed and will have a natural bow up trim.
The hull shape required to plane has a much higher form stability factor and so is less comfortable at sea. The trick is to keep the crew (wife) content while having a little fun. So, we give up some performance.
This sounds a lot like a distillation/mutation of Frank Bethwaithe's theories about faster than wind sailing in Skiffs. His idea is formed around the idea that the faster the skiff goes (planing hull) the less pressure there is on the rig allowing you to make better velocity made good against the win by back ing off somewhat and getting the boat plaining to windward. Similarly pointing up on windward legs and doing a dogleg reach with a tack in between is faster than a straight run. All these ideas rely on a hull that can go faster than the wind by planing. Typically keel boats can't plane. Some sports boats can but most blue water boats are built to be stable and their hull speed it the limiting factor. Hull speed is dictated by length so most blue water class yachts are long hulls. Surfing down waves gives the opportunity to briefly exceed hull speed over water because the water is moving faster than the mean water speed. You're moving faster over your gps position than your hullspeed. It's a known tactic in yacht racing. I'm not sure it has value in a cruising or passage following context because it takes a lot of concentration. If you really have to be somewhere sometime and you have dedicated experienced crew maybe this would have some benefits. Seems like an edge case to me. Luv and Peace.
I don't know anything at all about sail boats, but I thought they were a lot faster than that. I guess they are slow and peaceful like riding a horse, or a horse drawn carriage no need to be in a hurry.....
The net fuel burn on these boats when generators are taken into account is significantly less than most large sailboats (which power 60 to 70 percent of the time on average, and typically run their generators 12 to 24 hours a day).

These videos are great! It’s like taking master classes in yacht design from one of my favorite designers!
Beauty, functionality, and power results in luxury ocean cruising!! You have concurred the oceans of this world. Well done.
I just love your videos...GENIUS designs. Truly an honor to gather ideas, information and enjoyment from them. Thanks !
Wish you would show more of the interior and engine room, the systems, fuel capacity etc. Keep up the good work!
I would like to own one of those Dashew sailing vessels one day

Well done, would like to see it going into head winds.
They can't do that.
John Irby , oh oh oh oh not good then.
@@CaptMarkSVAlcina It's good as long as you're sailing downwind, but most of the time, the wings don't agree with where you're wanting to go.
See the recent videos for upwind performance. You may be a little surprised.
It is always nice going downwind. Try going into to find out what your boat can really do.
There are three recent videos discussing upwind performance.
we need more fpb videos
Beautiful boats

Congratulations On The Life Your Able To Live 🙏 And Thank You Very Much For The Videos 🙏
Same cross section as a Sierra Match King bullet. With ballistic coefficient of 0.505
The fashion police are after you for that ‘ bondage outfit ‘ from the 90’s
FPB: Fashion Police Boat
Facinating. Thank you for sharing.
thanks for the frank insight and for rekindling my own memories
Given the choice, transiting the Pacific on an FPB or other Dashew design would be preferable to anything else.
Great vid ya'll.

You will find a huge amount of detailed info on the FPB 78s and other designs at SetSail.com
that 68 ft aluminum beauty!!! AH !
I beleve one of the Deerfoots are for sale in the us, Johan and Malin in Ran sailing rewiviewd it. Wow what boats the Dashew's have made, love them!
What can one say , WOW .
Does that mean in metric car comparable terms, for a speed of ca. 25KM/h you need for ca. 100KM distance around ca. 100-150 liters of fuel?

Its a shame this Beowulf design was a one off. The only thing that comes remotely close are the Alubats, Garcias or the Cigale 16m
What? Only 70 yachts?
We never intended to be in the yachting business. It. just happened. We kept it small so that we could better control the outcome.
should produce a 40ft tri fpb
Why?

oh no STARWARS its been done.
Nope, it's just pissing down.

But flat earth nuts say you can't go to Antarctica!
Burning A GALLON OF DIESEL PER MILE is acceptable, is it?!?!

@@DashewOffshore these boats have enough deck space to be completely solar powered interior besides engines
