Dodger
When I had to decide on a dodger for my 30, we were faced with two choices. One, that was as tall as the boom and came aft to the jib winches that would permanently be up all the time, or one that could fold down just short of the traveler. We opted for the shorty. Since most of our sailing in Chicago is from May to October, the dodger is only needed for about two months. The shorty breaks the brisk wind enough for everyone in the cockpit except of course the skipper. It does not interfere with any rigging which includes the mainsheet winch, main halyard winch, traveler, vang cleat, and two jiffy reefing cleats.
