That is interesting, they did not even get the front beam wet!Just how much bouyancy do these boats have? From the photos it looks like the bloke in white [Spithill?] douses the assymetric then steers the boat upright while an unseen boat [large rib?] pulls from a line attached to the jib tack. seeing the AC 45 on its side [front and side on views] gives a different perspective to the hull shape,
Cheers,
