@@apollomorris9920 eh.. no they won't. If wing size were all that matters: why do you think for example human powered flight (I'm not talking about gliding or thermal updraft) isn't possible for more than a few seconds? We could just attach extremely big wings to our arms and keep flapping, right? The answer: because we're too weak relative to our weight. The same with boats: It's rather a matter of available power (sail area / engine kW) relative to weight. I'm not saying that foil size(/area) is irrelevant. It affects stall characteristics / slow-speed behavior and wing loading, but the thing is: when you're foiling in a steady-state, this ultimately means that lift and weight are equal. And 'equal' implies: with higher weight you need to produce MORE lift. Simply increasing the foil area is no solution. Even a perfectly shaped wing/foil doesn't "fly" on its own, without the energy you put in. A bigger wing is also confronted with increased drag that needs to be overcome. More power is the only answer to that. And when the boat is so heavy that the availability or the required amount of power becomes unrealistic (because the boat can't carry such a sailplan without capsizing or structural damage) there you have it: conventional cruising boats will never foil !! - at least as long as we're talking about sailing vessels and not power cats with insane horsepower.
One must dream! If you dream it, foiling on cruising catamaran is possible. Dream about it, because one goes so fast, less food and water will be necessary, therefore reducing weight. May be a couple hand held gps/vhs radio. Small engine of course and vollà, there you have it a very light foiling cruising catamaran.
@@___Chris___ I mean those are just engineering challenges right? Lighter and stronger materials and better building techniques can pretty much fix all the problems you just mentioned as that will both lower the required lift and increase the possible sailplan. The AC75s are already flying 6.5 tons, that's not *that* far from a outremer 45. With so much innovation on so many fronts I think it's pretty outdated to say that cruising boats will never foil. We obviously won't be flying a Sunreef 80 anytime soon, but I think foils will slowly but steadily work their way into the commercial market, the only question is how much time and innovation it will require.
Had a hobbie 16 on Maui, I crossed from Maui to Molokai! Sketchy! Terrified to say the least, I remember calling on a public phone in a park just outside Kaunakakai to a pre-recorded marine whether forecast: : “Small craft advisories are in effect for all Hawaiian waters due to marginal sea and wind conditions “ I took the jib out and riffed the main sail and crossed the Pailolo channel, at the time I didn’t know the name of it. It was 1988 and I remember it like it happened yesterday.
Love the G4 concept. 1st video i've seen since... well you know. I would love the canopy to extend out to the galley, open one side up for a head and storage and turn this bad boy into a long term option.
@@DNAPerformanceSailing I like the above suggestions for more usable space on board and would like to see your other designs. What progress has been made sine 2015?
I’ve seen 2 foils on a sailboat in somewhat of a V shape, so if the V or foil is fully submerged the foil provides maximum lift.however once the foil starts coming out of the the water the foil looses lift and the boat goes back down gradually,” one would hope.I guess electronics would work also but then the rudder will have to be another foil with a trim tab connected to the electronics to adjust angle of attack. Fush I went to the deep end.
JAW dropping footage. Absolutely amazing!!! I cannot wait to see retracing foils as standard on cruising multi hull sail boats
Cruising boats are way to heavy for foiling.
@@stashgumbo bigger foils will fix that.

Sailed at 24 knots on a 55 try so really enjoyed the work that goes into this boat - WOW .
Nice reminds me of my days sailing a Hobie-Cat, flying a little hull, and 25 Knots plus....

You guys don't have a walk through of this boat do you?
Love the music!

Everything is possible with us:-)
You guys are awesome. Keep up the content.@@DNAPerformanceSailing
@@DNAPerformanceSailing I like the above suggestions for more usable space on board and would like to see your other designs. What progress has been made sine 2015?
For the Volvo Ocean Race?😁
Awefull music but nice pictures. Some datasets would be great.
2015?? Really? How is it I'm just seeing this now? And how soon can I buy one for blue water cruising?
The music made this from 10/10 cool to like a Solid 6
SO DOPE!🤩
Nice background song. Which song is this ❓
This is "The Nights" from Avicii 🎵
@@DNAPerformanceSailing Thanks 👍, please make one video on fastest monohull, catamaran and trimaran for circumnavigation for solo sailing
Impressive, bet the price is too...
So awesome
lol some rich person is gonna die trying to sail this catamaran.
Stability needs to be controlled by software, the only way to make it safe!
Intresting mayby
If you wanna "stay safe" stay at home.....
Until the battery fails, or a glitch in the software, or salt on the electronic card, or....

Looks like is just matter of time to stuck the nose in the water.
Isn’t this a gunboat G4
DANNNGGGG
🙏🏽🙏🏽
😮
WOW
Looks a little unbalanced, you have to start somewhere. Thanks for sharing, clearly I'm a little slow to find it!
Ok this thing looks bitchin
