No joke as my strong 170lbs couldn't right this catamaran by hand though I was lacking in knowledge and experience. It sails fine in medium winds with me on it though the back of the pontoons are only exposed maybe 3" above the water.

I don't see how the mast and triangle shroud, poles could be sealed unless there's a inner rubber stopper or such. The are just aluminum poles held in a cast socket with a regular bolt.

The downhaul line for the sail is extra long so that could be used as the righting line as it's "attached" to the base of the mast. The only problem is that it is quite thin. I could wrap it around my hand and get a decent grip.
