What do you think of the idea of putting the main boom vang on a circular track so the boom angle and boom height (sail twist) can be controlled. I guess this is the sort of system you would have had in your cats many years ago.
I guess it would alssuito roachy mainsails.
Do you think it could be an effective and efficient means of mainsail control for a large yacht with a shorthanded crew?
We used the same approach on Beowulf for both main and mizzen. If you have space for the track, it reduces compression on the boom and mast and offers much better trim control.
