I get a lot of **** in my wooden sailbox. It's near the shore, by some trees and underbrush; and I built it with a 1/4" gap on the bottom of the sides for drainage/ventilation. They do like to get into the rolled-up sail. Often as I raise the sail, they'll come raining down on me. I just have to make sure my wife doesn't see them, or she wouldn't come near the boat.
