Doesn't quite answer your question, but I just stumbled across this: it's a video of SailRocket doing 44 knots...

So far there are three threads on the Wot boat including this one discussing its compeditors. Would be good to keep all discussions in one thread.

Note that the Sailrocket vid is a year old. I think it blew up shortly after that run. Maybe they are due for another try soon?
But a real Ozzie tryer is Stephen Bourne. ( http://scienceinpublic.com/freshinnovators/2004/stephenbourn/stephenbourn.htm )
He has got some bits fabricated for a full scale machine , I believe.

Looks like a Sailrocket but control is by two joysticks and only the foil is in the water.
"Fly by wire" might let one sail it from the shore. That would suit me fine..

Hi guys,
I just got back from a week in beautiful Port Douglas where it blew 15-25 knots from the south east every day I was there
When I was coming in to land over Botany Bay what did I see??? The Wotrocket going though its paces off Kurnell Hope it blows soon to see what its potential will be.

not sure Yoyo, from what I could see it looked like it may have been being towed by another boat...? Damn pilot wouldn't slow the plane down for me so I could see closer

Anyway, when you think about it, it's still very amazing to see how much technology you need to throw in, when you see how fast a human body can go with only a board and a sail !!

And a good technic, a good balance ... and few neurones missing !
