Too bad the G4 project
fell off the radar
after that famous wipe. Software
could have solved
the flight control issues and there might have been a niche of pioneers with the foiling cruising boats. Just too many safety
issues i suppose, but one can always dream..
I don't believe cruising boats are going to fly anytime soon, like your saying they need to loose a lot of weight to get there and a 4,000kg, 48' cat will be pretty low on features. A lot more race
boat than a cruiser, however it would be nice to see them get started like the G4 and see how far development could go.
It is early days in development, listening to discussions on specialist forums
it seems there is a lot of disagreement on just how it can be used so there must be lots more to learn. (disappointingly it was working a long time ago but it didn't get the momentum it should have back then - where might we be now)[/QUOTE]
Lifting foils arenít just about flying - they are also about efficiency. The 18m cat I was talking about doesnít lift
with its lifting foils - theyíre about reducing drag by reducing wetted surface. https://boatingnz.co.nz/boat-reviews...ill-18-5m-cat/
This design evolution seems reasonable for cruising cats, with the resulting boats not needing to be silly light (the 18m cat is 12,000kg lightship). Iím not sure how twitchy the sailing characteristics are, but I do know that they sail offshore
with a full crew and keep the boat powered up for 500+ mile days (NZ - Fiji
including a pit stop in Minerva in 3 days). Whether the boat can be depowered for a cruising couple is the question.
