Watch the first foiling cabin-cat on her first sea-trials.

https://vimeo.com/125378004

Its a Gunboat G4, Dutch design and build in by
Holland Composites.
Apparently, it has a hydraulic mainsheet adjuster.
Watch them release the traveller just that tiny moment
to late.
At the end of the video I can hear the Dutch guys say;
" what a classic stupid mistake"

Grtz, André

no worries about the "Expensive " ... this is for the "champagne and cheese" demographic

What do you think made it expensive? I never heard about significant damage.

They broke two battens... that probably cost more than most of the beachcats you'll see. 😆

Also turn the sound down low if you are at work, loud F bomb at the end of the video.

Design failure, clients walking away. Not a good start for a building-yard
which almost went bankrupt on previous projects.
Expensive in the meaning of bad publicity.
If the waters over there were shallow, expensive carbon mast.
Nevertheless, I really love the boats they are building at that yard.

Design failure

design seemed ok to me
- looked like human error (allowing the foils to foul, not heading downwind, and not traveling out or dumping the main in time)

that video of the capsize really shows how good the Kiwi's were in the near capsize in the America's cup. they reacted perfectly to prevent the capsize and the interesting thing is that in the spectacular capsizes the crew does not react at all and the boat goes over.

Design looks ok, allright. Most French monster-multihull build for atlantic
record crossings and races have some sort of inclino-meter which is programmed to
release any sheet/rope/tiller you want after a certain moment of angle is achieved.
Something like this. http://www.oceandatasystem.com/?mode=developpement-ods-upsideup
On a radical design like the G4, wouldn't it make sense to put on a system
like that from scratch?
Especially when its purposed build for the "champagne and cheese" demographic 🙂

As for human error, you can see in the vid, they are just to late releasing the traveller.

So much for design talk.

I love the guy in the comments section talking about not drinking. I thought he was kidding but I don't think he is! Good frickin advice, that's for sure.
