Good thing he wasn't on a foilboard,he'd be out buying some extra freezers.
On that note, what's the biggest animal ever killed by a foilboard? Probably not a humpback whale...

Re: Kiter hit whale in San Francisco Bay

The liter seemed to take it pretty well.

I would have crashed and soiled my wetsuit...

Rail slide? No... Whale Slide!

Re: Delta Hydrofoil - First ride

Sounds great!

What were you going to buy, and how did it compare to the Delta?

Re: 7 kn of wind, who will win AC45F (America's cup boat) or kite foil?

I'm beginning to think we should just be comparing two numbers: upwind VMG and downwind VMG.

Ideally they would be taken with similar wind speeds (7knts if we go off the title of this thread).

I'm beginning to think breaking down the race videos might be the only way we get our two numbers.

Re: 7 kn of wind, who will win AC45F (America's cup boat) or kite foil?

Ok, so both craft are highly capable from 7-25kts wind. AC50 by changing foils, kitefoils by changing kit sizes. I found the polars for the AC45s from a few years back and they were unimpressive. Everyone has opinions, but I don't see this getting settled without either: A: a match race (which would...

Re: 7 kn of wind, who will win AC45F (America's cup boat) or kite foil?

Found a polar for the 2013 America's Cup: https://goo.gl/images/sC9xK6 From: http://www.cupinfo.com/cupstats/index-ac34-statistics-polar-plots-02.php I'm sure the AC boats have gotten faster with four years of development, but VMGs of 20kts upwind and 37kts downwind (absolute best case, rounding up,...

Re: 7 kn of wind, who will win AC45F (America's cup boat) or kite foil?

Certainly if the course is a bunch of slalom buoys twenty feet apart the kite wins. I guess I hadn't seen video of the AC boats in swell. Not sure who would have a tougher time with it. A foil kite has a lot of the same advantages as the AC wing sail. A traditional sailboat mainsail is actually very...

Re: 7 kn of wind, who will win AC45F (America's cup boat) or kite foil?

Seems like a kitefoiler would win in winds too light for the AC to foil, so 6kts? And seems like the kitefoiler wins by default when the wind is too strong for the AC to be safe with its wingsail. It does seem that the wind range sweet spot of the ACs has expanded now that they have multiple foils t...
