One of the Hydropter varients ?



Hey Smack ... this thing could get up and boogie ...



It had a funny nickname but I forget what it was. (Found it "The Caspian Sea Monster')

I bet for the $10M price tag of an AC72 you could get a pretty fast power boat... and you wouldn't need a crew of world class sailors to get it up to speed either.

No doubt. But I'm talking about the technology itself...which always gets cheaper over time (Moore's Law anyone?).

The AC72 maybe. But this one did a fine job of it...hitting 40+ a couple of times...

Re: AC72 - On Foils

GD mentions how the chase boats couldn't keep up in the sea-state...

What was that Smack .... I'm thinking non foiler ? I was more of mind that foils long distance offshore would be a problem when it came to ultimate strength.

Re: AC72 - On Foils

That's Loick on his Banque Populaire V. And you're right - a non-foiler.

Agreed - I have no idea what foils would do to the offshore scenario. I was thinking more the multi.

I can't wait to see top speed on the foilers though. Just crazy that they can balance all that load against a single foil.

Re: AC72 - On Foils

Peyron did his loop at an average speed of 26knots. If you could hold a foiler together for long enough .... wheeeeeee ......

Re: AC72 - On Foils

I interviewed Jim Brown recently and he gave me a quick lesson on hydrofoils being the next big thing. I found a video of the AC72 up on it's foils. Can't post here yet but it is on the website at - thesailingpodcast.com/jimbrown
