I'd buy one of those portable sheds. If you can't do that i'd have a cover made. If the boat has a paint job then the cover must have a sock type cover made that fits on before the typical type cover goes on. Most covers are water proof until you wash them so that will help in the rain. You can cover a boat with plastic over the other cover in bad weather, you just have to take it off when it's over (bad weather) so the boat can breat again. The guy who makes my covers also made me one that covers the whole boat including the trailer. Nice deal when I have to leave my cruiser outside. Covers can get real expensive, but no way near repairing a damaged paint job or gel coat.:idea:
