Re: Rebedding Water Tank Lid
Our Ontario 32 has a very similar tank. When I bought the boat, there was just a plywood lid and the bin was used for storage. However, it was intended to be the holding tank and since boat did not have one, I converted it.
I made a new cover out of a product similar to Starboard. It looks just like the one in Toddoh72s first post, except white.
Not much sticks to the plastic I used, so I did some experimenting. In the end, I used Marine Goop! However, I have at least twice as many screws as Toddoh and each one has a large fender washer. The span between washers is quite small. (I learned to do this when trying to seal external bolt-on Plexiglass windows on an earlier boat. They always leaked until I added more bolts. Bolt or screw holes need to be slightly oversize so as to allow for some movement.
My holding tank has been in service now for about 10 years. No leaks and no smells (well ventilated tank!)
ADDED: Our water tanks are under the settee berths. They may have originally had covers, but are now glassed over (problem solved!) There are clean out ports.
