Re: Mainsheet behavior
RG, above, is correct. I'd add that *all* conventional travellers must be moved above the centerline to center the boom. As RG says a cabin top traveller may not need to be as much as a brigdedeck or transom sheeted rig, but it must be up some distance.
I would guess that on a 32 foot boat with a bridgedeck traveller in a nice sailing breeze the boom-end would indeed be low by 6 to 12 inches unless the traveller is raised.
On proper boats, with headsails, in typical conditions, it is necessary to center the boom to give respectable pointing performance. Dinghies are an exception, as are overloaded cruisers, and heavy air of course.
My feeling is that the vang increases the need for raising the traveller. Because the tension, and therefore the centering force, of the mainsheet is reduced.
