Re: Mainsail twist & traveller position
No. Generally, to sail closehauled in light to moderate winds, the traveler should be set along the centerline, with the boom approximately pointing at the backstay. The vang should be set with light tension. To set the twist, the top sail batten should be parallel to the boom.
In stronger winds, when the boat begins to heel excessively, flatten the mainsail by increasing luff tension and outhaul tension, ease the traveler to leeward in the gusts, and then bring it up to windward in the lulls, but never with the boom further to windward than the centerline. If the boat has an adjustable backstay, I also increase backstay tension. I suggest that, when you are playing the traveler up and down in the gusts and lulls, you watch the knotmeter to see how each adjustment affects boatspeed.
Generally, increasing twist increases power, and you might decide to increase the twist slightly to help power the boat through a chop, but I don't recommend letting the top of the sail twist off to keep the boat on it's feet. IMO, if you have used all the sail trim techniques to flatten the sail, and the boat is still overpowered, then the better choice is to begin reducing sail area.
