Hi all,
I should say that my leech is hopefully always twisted. When I am talking about trying to stop leech twisting, I mean excessive twist, like when you are trying to get on trap looking for maximum power.
I am basing my mainsheet tension on Glenn's advice when he was sailing behind me in 15 kts. telling me to pull on more downhaul to incease twist, but also more mainsheet tension at the same time, idea seems to be to depower sail to the point where you can keep mainsheet in tight. It is improving my upwind speed with this main. By the way Glenn cut this main after sailing Altered and having good look at mast, I think he has it right, it is just different to what I have used before. Irwin main was made without the boat rigged or in the water and was a good result considering.
Regards Gary.
