Gotcha! Hey Bob, you're right it is fun.

That looks very cool... but is it any faster. I mean, they are still dragging around that anchor of a bulb.

That's hilarious. SOOOOOOOOOO much work to try and be a multihull without actually being a multihull.

Is the purpose of those foils on mono to raise the boat or to add to the righting moment?

I would guess the later.

There is a fair amount of lift angle when the boat heels enough to engage that foil fully. I would say that it is primarily to reduce wetted surface area of the hull by making it lighter through the water - but there is probably some additional righting force with it too.

We sailed it (S9) at TFW at Lake Garda about a week and a half ago, it was a fun little boat.

Be informed that the S9 wiil sail (or better fly) in the waters of Texas before the end of 2015.
I was told that there is still room in the container.
The bill for the complete boat (beach dolley with big wheels included) delivered to Texas is 17.5K USD
(14.5k EUR is the price ex factory plus 0.8K EUR of shipping).

I think Jake is right. I wonder when will see enough lift off the boards that they need stabilizers on the rudders. Must happen eventually I imagine because foiling, even with partial lift, is just too fast to ignore. Amazing that a 12,000 lb or more keelboat is that lifted already.

Caftan, would be great to see the S9 develop as a junior boat if that makes sense. Small and perhaps more stable with wands on both sides.

For those who want to race foiling boats, you can alway get a foiling A-Class for about the same price as the S9 in the US (from $22K to $25K or so) and have a few hundred boats to race with.

Thats a sailboat in that video?

With the amount of spray coming over the "bow" I was certain that I was watching a video of the next generation of "green, wind powered" submarines that I'm sure we're paying for.

Another option on the market is the Reg White designed "Whisper" Jon at NorBanks Sailing just took delivery of a pair...

I just saw a Nacra 15 on a trailer with the foils... Looked like a nice junior boat (perhaps to ramp-up to the 17 - once they fix all those issues)...
