Thank you and 3 questions?
1. Jumpers? You mean wires like stays at the top?
2. Even if I put Permanent backstay, wouldn't it be helpful for making rig
3. Openning up the top of the main means that when I pull the backstay
it just help to twist (=open) the main. isn't it related to move the
draft back of sail that help for beating?
