Hi guys, I am new to this forum, I am glad to be here with all of you.

I have bought a formula kit recently: a starboard 162l, and 11m sail. I am 72 kg weight, thin fit. I have tried to handle it, but it's impossible to me: I can uphaul it, with some effort. But when uphauled, the weight of the sail avoids me to controll its position. Perhaps is it too big sail for my weight?

I have read several forums where the recommended sail sizes are from 10m minimum. But If I cannot handle an 11, then neither a 10 (only 1m less). Is it possible to use a Formula with less sail, for example a 8.5 o 9? I can handle without any difficulty a 7.5 (8.5 tried once on a slalom, and ok). I would like to plane from 8-9 knots. I have seen at a sail calculator that an 8.5 would allow from 8 knots, but.. is it realistic? I only have one fin (70cm).

Thank you very much!
