We’re of the “don’t-do-it” camp for a few reasons. First, once bottom paint is applied to your dinghy, it can be very difficult to remove it without risking damage to the material. Second, if you ever store the dinghy on deck or deflate it for longer storage, you can be sure that paint is going to rub off on things you’d rather it not foul—for instance, tacking headsails, topsides, or the deck.
