Right now, I just use a quick release, expanding rubber plug in my Despersia, and it works SO much better than unscrewing the Despersia cap, with the water trying to drain thru the holes in the Despersia threads...not to mention potentially losing the cap if I unscrew it all the way. My rubber plug quickly yanks out and stuffs back in and is on a lanyard, so it can't go overboard. I have a Puffer and just drilled a hole, using the same type of rubber plug and it works great. No bailer at all, but just the hole and plug. The Elvstrom or Anderson type bailer WOULD have to be out of the way....like near a cockpit wall, etc??. Fully retracted, they shouldn't get damaged, loading the fish on a trailer, etc.
Any rate, I know lots of different dingy style sailboats use them, but have never seen one on a Sunfish. They are pricey if buying new, but if the work better.....?
oh,....yeah.… I use the same type of plug on a transom drain too. Works great for that "errant" water that is coming in from somewhere, when bashing about in heavy waves ;-)
