Rc Sailboat Voyager 280

First day toying with an rc sailboat. Model Playstem (or playsteam) Voyager 280. Very gusty afternoon, impossible to have even a single leg of a course. I'd say the ideal windspeed is about 5m/s or 9-10 knots Anyway really fun! For me this is the first time ever controlling any sail. Waterproofing the hatch is a must. I heard some people put closed cell foam inside. I just made a gasket out of a thin stripe of EVA foam sheet. It worked like a charm.
