I lubs that video.

IMO, if it's a boat powered by the wind on a sail, it's sailing.

My preference is being down on the water but I wouldn't mind taking a moth out once or twice and I'd crap my pants if I got a ride on the L’Hydroptère.

Funny you mention aircraft-like redundancy. The control pistons on Hydroptere's foils are developed from the landing gear on Dassault Aircraft's Rafale jet fighter.

I have no doubt that some will be inconsolable over a sailboat that is dependent on electronics. I won't. However, to be offshore with such a vessel will require aircraft-like redundancy, which even our current electronic niceties rarely have. For that matter, to eliminate electronics from legit sailing would be like eliminating them from legit flying. Ridiculous.

However, I seriously doubt that these boats are going to be simplified to run with just a couple aboard. It seems to require what amounts to a race crew to deal with that speed. Pitchpoling in 8 ft seas is probably a real risk and managing pitch, while on the foils, must be a full time job. There is no way to pitchpole or even knockdown our boat in 8 ft seas.

Remember this is an experimental craft. If the development costs could be justified we may someday look back at our monohulls as relics of the past.

When the Hydroptere has no sea conditions to foil it sails like a regular trimaran.

you were saying that was a boat to sail exclusively in protected waters. You are obviously wrong, they had plans to a trans-Pacific record. Do you call that protected waters

Besides wanting a ride on one of these, thanks for the link to this website, very cool videos. Trimarans have been around for a long time and have been proven in ocean conditions, although they are as easy to flip as a Hobie. I haven't seen one of them up on foils yet in these kinds of ocean conditions. It may not be possible because the foils would be intermittently in and out of the water. It would seem that they need to stay in constant contact to lift the hull up. Would not the hull act as a bridge in a 10' sea, lifting the foils out if the water?

Since they want to sail across both the pacific and the atlantic, the capability to handle those conditions would seem important.

Regardless, I'm not sure how much it matters when one is discussing what constitutes sailing and what doesn't. Lots of sailing happens in an insignificant amount of swell in boats designed for flat water.
