Oooh 1.5 ton blades whizzing about on an unstable platform.

So we've gone from 14' two person dinghies via 18' three person and 30' 9 person dinghies to 75' 12 (or so) person dinghies.........

Presumably they should provide enough righting moment that the boat can move forward, get flow over the foil which will then providing further righting moment (lifting surfaces well to leeward of boat mass), before really cranking on the power.

Thanks Mozzy, not seen that till your post.

1.5 tonnes of polished knife at head height traveling a 40 knts. That will be interesting. I wonder if Sabatier will be a 'headline' sponsor?

I'm still trying to work out how these things are going to stay upright when not moving forward at pace with no keel and 100ft mast. I know they show a 'dock position' for the Foils, but unless the foils are made of lead, this an't going to work. A bit oxymoronic to say the least. If they use water for blast, water when in water weights the same as the water around it. Plus they are going to scythe to death the apposing crew off the deck in the Pre Start if they even attempted a luff. i.e this means less match racing than the Cats, which was pretty good from my perspective! Basically there's potential for a lot of death on the AC hands, with all the capsizing and close quarters danger, in my view.

Can't wait to see Ben pulling these aggressive dial downs with the full Swiss army knife on display.
 
Foils outside max beam are a massive negative for match racing. Could be a good trickle down for ocean racers though where proximity and frequent manauvers aren't as much part of the game. Having said that, these weight foils will be battery powered. Not sure how that will trickle down to ocean racers.  

Otherwise I think the racing will be less close. Essentially, once foiling the new boats won't be much different to the cats (except T foils with flaps moth style, rather than whole foil rake). However, as a 'launch pad' for foiling the mono-hull will have much more drag and much less righting moment. The speed differences will be huge... as if they weren't big enough in the cats. 

Personally, it seems like a lot a effort just so we can the thing a monohull. I like the Cats foiling, and I liked the old monohulls too. They produced different racing each compelling in their own way. This seems like a worse of both worlds design (for match racing).
