I would use amalgamating tape for patching hoses, mast boots, etc. No adhesive, just stretch it well and it sticks to itself. Duct tape definitely has its place on the boat, but once the adhesive is wet it becomes compromised. I like Gorilla tape, but careful on wood and thin laminates...it will take part of the wood or laminate with it when you peel it off. Gorilla tape adhesive doesn't do well when wet either. Bottom line is that you'll have to dry the surface before applying any duct tape to it.
