I have a 60's 25ft Coronado that I have finally hauled out and am working to restore. My biggest problem has been my
cockpit drain failing, and my
cockpit filling with
water during the rainy season. Below
deck, the valve for the drain is completely corroded and seized up. Also, the
boat came with a
head that no longer worked, so I removed it. Only problem is that the waste-out through-hull is a total mess of
fiberglass and I wasn't able to cleanly cap or
plug it. This is the first
boat that I have had and I don't know much about through-hulls, but looking at the ones that are installed on my boat, they seem unique at best. I was under the impression that most through-hulls were backed on both sides and sandwiched the
hull, but now that I have a good look at the bottom, they appear to just be pipes that are glassed right into the
hull. Right now I have a port-a-potty onboard, and my original intention was to just glass over those through-hulls in an attempt to minimize possible failures, but people have been trying to talk me out of that, saying that it is better not to limit future options.
Basically, I want to make the boat as simple and worry-free as possible, and I don't trust the most of the
hardware that is on there at the moment. What should I do? Glass over any unnecessary holes? Should I cut out whatever is going on and then install new through-hulls and just place a closed seacock on any that I am not currently using? Any
advice or experience with these boats would be appreciated! Also, any recommended sources for this
hardware?
