I do not own a full race sail but on what I have heard and read these sails are meant to be used overpowered. I guess they take out a 7m2 with quite high winds (for me at least, an intermediate sailor).
Anybody else, am I wrong?
What do you refer normal winds?
Sorry if I misinterpret you, but maybe the sail is well trimmed but it is meant for more wind
May be if you detail more on the board type and the range of winds (+14kts?) you expect it to work, you can be answered better
Hope it helps
