Salt Air Corrosion Concern
Gas storage - certainly somewhere outside the boat where the fumes won't settle down inside and away from any forced air heater exhaust. We lash ours to the toe rail (aluminum peforated rail).Bikes - my concern here would be to protect them from corrosion. We had a beautiful Honda 650 generator which I stored under the center seat behind the wheel for a month and it got serious corriosion, even the aluminum parts. Bikes, on the other hand, are somewhat designed to resist corrosion; however, salt air is going to be really rough on them. To make them fit in a smaller space, consider taking the wheels off (quick release?), and seats (ditto?), and storing the parts where they'll fit. Anything stored on deck would hold up better if fully covered, say with canvas or plastic tarp. Spray metal parts with Boeshield or similar??? Five is a lot, maybe just take a couple and take turns or rent like the previous post said. Unfortunately, a fine scratch on a ferous metal frame will no doubt turn into a rust streak no mater what happens but a bike on vaccation is a fun thing to have.
