Re: Twin mainsheets...why?
Earlier in the thread someone commented that German style sheet with a vang works as well as a more typical layout that has the mainsheet attached to a traveler. With a single sheet setup and without a traveler, you cannot control twist and still be able to center the boom. The issue becomes if the leech is eased enough to allow the leech to open for the gradient wind, the boom is well to leeward of its ideal position. That is an issue until the wind is blowing enough that the sail needs to be bladed out, in which case vang sheeting works fine.
There is an old school set up with a separate mainsheet tackle on each side of the boat. This allows twist and rotation to be adjusted independent of each other and allows the same range of sail trim as a mainsheet and traveller. In practice it is a pain in the butt to use since the type of adjustment that would normally be made with the traveler, is made by adjusting the tackle on both sides of the boat, and it is a bit of a trial and error proposition since you don't know whether the adjustment on one tackle is right until you adjust the other, so you end up making a lot more adjustments.
All that said, for some reason almost all new European boats are being delivered without travelers these days. I think that results from the trend of mounting travelers on the cabin top and mid-boom travelers are relatively so ineffective that there isn't much loss to eliminating the traveler.
