I put a dorade on the bow that vented into the space in the bow in front of the V-berth that seemed to help. You had to take it off for racing to not mess with the jib. Also, because I mostly raced PHRF, I took the cushions off which seemed to help the mildew issue alot. I think it allowed a little more air into the lockers to keep them dry. Maybe you could just prop the cusions up a little bit when you leave the boat.
