Guys - I think I've missed a trick, having only sailed in very heavy weather so far. So I rig the boat, set off, get on the first beat and notice the boom is way out despite the mainsheet being in as far as possible. Obviously the traveller blocks aren't centralised which I guess would solve the problem. Do I sit onshore and bang as much vang on as I can before setting off to sort this problem out, or is there another trick that has passed me by?
