Then add folding pedals and the bike becomes slim to make it easier to store. Put it in a sunbrella bag and store it on the rail if there's no room below.
Not sure if you would need to remove the handle bars, if you loosened them, you could turn them parallel to the top tube.
Not sure how much or how often people would use their bike, but I recently saw a bike rack that fit on the stern of a sailboat
