Model olympics underway, Fila: new main sail

Yesterday it was match racing time, 8 competitors went head to head.
I finished second overall,
lost one, but won all the other races.
There was no wind on Koseze pond, so the "drifting" was on..     ..the reason the first race was lost is:http://www.youtube.com/watch?v=LR3uFfT-qtM
I lead around the first and second mark of the triangle, turning around the second mark my sail wouldn't pop to the other side, so i stopped completely, there was not even enough wind to open my bum, so i could sheet in quickly and pop the sail..
..anyway, my mistake or boat problem, tomorrow is a standard regatta.
Drifters are expected, so i finished a new sail for fila, which was laying around unfinished.
It has less luff curve, so it pops to the other side much more easily.

Today i hit the pond when the wind was dying, set it up properly in some 5-7 knots of wind. Then took on the drifters. This sail seems to be better suited for these kind of conditions as it pops really easy.
Will do a fuller report of the tomorrows race.
