No mainsail traveler…
Cf. an earlier discussion on this thread: I don’t like that at all. It only works when a very powerful downhoal is provided, which is seldom the case because of the enormous forces this generates on the boom.
By "downhaul" you probably refer to the boom vang. Also does require a much heavier boom section, but I would think this is compatible with the park avenue booms. I do agree it will be one of the most important decisions when choosing a next cruising boat. It's nice for the family to do cockpit-friendly gybes, but I will not sacrifice proper sail trim! One final thought: I wonder if masts keep "moving" back, with high aspect mainsail, shorter booms and self-tacking foresails, maybe travelers will become history, just like backstays in some cases!
