Does anyone besides me think that foiling tris look like some sort of aquatic bug?

That is a very big yacht with very little space inside. It's not for everyone, but I'd probably enjoy it as my second big yacht...

The desire to have a "big" yacht on a limited waterline is how we got to the behemoths that most folks here love to denigrate. No open decks, no defined superstructure, just decks and decks of full-beam, full length enclosed space. Not my cup of tea, either, but that is what the buying public wants.

The advantage to a trimaran motoryacht is that, though limited in interior volume (how many people do you want to go cruising with, anyway?), they are wonderfully stable and very fuel-efficient and faster than boats of similar length and twice the horsepower. My best example of the stability at speed of multihulls is when I had to go visit the head while travelling at eighteen knots between Barbados and St. Vincent. Seas were about normal for that place, about six feet, and wind was on our aft quarter at about 15-20 knots. The boat was a 60-foot power cat with a 28-foot beam. I left my bottle of beer on the cockpit table, unsecured by anything. It was in place and unspilt when I returned.

Nigel Irons had something similar to the OP about 45 years ago.

Did it get built?

We did a lot of out-in-left-field multihull design studies when I was in school in the early 80's, too, and I got to do a bunch more based on SWATH hulls for a military contractor a few years later, but the hard part is finding a client willing to pony up the money for a real one.

Well, if you'd just arrange for me to hit a big lottery jackpot... :D

Look cool, in a Blade Runner way.

But what's it good for? Not for fishing or swimming or sunbathing.

Looks like the idea is zooming from point-to-point, inspiring awe, while your pale and pudgy guests get savagely drunk.

I dunno, Chip-skiff; taking the family on an extended cruise in a fuel-efficient, moderately fast, stylish boat seems to be a pretty desirable thing to do. As for swimming, there are lots of places of varying heights for the kids (and adults) to jump into the water from, and the stern platform and steps make it easy to re-board. Sunbathing is quite well accommodated on the large sunbathing pad on the foredeck, and it is easily reached through the central door in the windscreen. You got me on fishing, though; it probably isn't as good at hunting wahoo as a Bertram 42, but then, neither is a Trumpy or a Chris-Craft Constellation. Different horses for different courses, eh? As for the pale, pudgy drunks, well, it depends on who you invite. Not everybody has trailer-trash relatives and friends.

But you don't really want me to pop the bubble of your pre-conceived notions of who owns boats like this, do you. So you just keep thinking that the folks who own boats like these behave like the ones portrayed in a Rodney Dangerfield movie. In the meantime, I will remember my actual experiences on luxury yachts in the Caribbean and here in Nova Scotia, and know that my reality was much different than your imaginations. Gotta hate them rich folk, right?

Kind of like a big one of these:

which in turn is kind of like a small Earthrace / Ady Gil, which I've been aboard but don't have a photo.

Because fuel efficiency really matters when you can afford a boat like that. It's just a way of saying not only am I rich, I'm also a really quirky interesting guy. But that's about as far as it goes.

That must be a rather cool boat to play with, AK. But it would be crap for sunbathing or fishing...

Not Shuttleworth but I find them interesting;a green powerboat.

A sailing tri with foils that came to an unfortunate end a few months ago and I think mmd in particular will find the steering linkage worth a close look.

Basic question: why are these boats so fuel efficient? I have my theories, but thought I should ask people that really know
