That mainsail is a tape-drive right ?

3D shaping of the mainsail, that sort of thing ?

I think Marcus is on to something here. His sail at the GC 2007 was really light and withstood the abuse of GC 2007 perfectly. A pitty that the shape and luff curve wasn't really there yet but when it is then I expect it to be an excellent F16 sail. Lightweight, strong, good looking and with a good shape. Less weight up top the better right !
