So how did you seal the PVC to the fiberglass ?

CrazyFish was one of the first boats to PVC lids rather then the plywood lids but the seal between the fiberglass the PVC has been less then satisfactory. Have the the handwritten instructions on how to seal then and did this twice on both water tanks quite awhile ago, but they still leak a bit. Have to be very careful that I don't overfill the tanks.

For some reason the holding tank has been solid and the lid has never been off.

Also get leakage around the inspection port.

PSC is selling fiberglass lids for the tanks but the cost is what you would expect for a $300,000+ boat.

Have been thinking of building my own fiberglass lids or just replace with a marine plywood+glass+resin lid.
