Reading what you said about the bailer, I'm glad that mine has a metal "De-Persia" bailer, that was put in by a relative at one time, and I guess replaced the plastic one. I'm guilty of stepping in the cock-pit while I have the boat on a dock, and I do it all the time.With a dock, it's better to pull the Sunfish out of the water altogether, and leave it on the dock. Keep in mind that the plastic bailer is subject to damage when you step into the cockpit on a dock.
Exposed sail fabric coloring can be bleached by the sun, which also weakens the rigging lines (somewhat).
Rain has a way of finding its way to the cockpit floor. If there are cracks in the floor, then the rain water can seep into the hull. When the moored hull is lowered by rainfall, any daggerboard defect above the waterline will then allow water inside the hull. Not good.
As written often before, the Sunfish is happiest stored on its starboard edge, with the drain loosened or removed. Only a climate-controlled garage would be better.
