Exactly!!!! We've previously seen that sails can't be made the same. so don't fool yourself neither are hulls, hardware, masts or rigging.
I do accept that using the trap wires is the most accurate method due to "blar, blar,blar" but lets be fair we are not Olympic Sailors.
I'm sorry I seem like a killjoy but I have yet to be convinced that Club sailors who take moor interest in boat tunning rather than boat handling win races?
Where I sail there is a F18 sailor who has digested every F18 tunning/racing guide and he is fast when he's not upside down.
