[quote=Andinista]If you are evaluating adding a boom, that decision comes first because the mechanism is opposite. With a boom the outhaul tension works against the mast producing rotation, the mast rotation device restricts the rotation produced by the boom. The rotation arm points back and restricts the rotation.
Without boom the rotation arm points forward and you pull it from the windward side against the front beam (typically) to increase the rotation, normally downwind, that system cannot restrict rotation.
I'm not sure that mast rotation is your first alternative to flatten the sail, outhaul and downhaul come firts. You don't have an outhaul but you should have grommets to attach the mainsheet hook.[/quote]
