Last year my wife and I bought our first boat, a Catalina 250. We
love it, and it is just the right size for us in Colorado.

Over the summer a problem developed between the cabin and the hatch.
The hatch cover slides toward the bow to open. It slides on a thick
vinyl (I guess) tape to protect the cabin's fiberglass. The tape has
deteriorated and separated from the fiberglass, and I need to replace
it.

Can any one suggest where I might go to get the replacement tape? I
have tried West Marine and other Internet boat supplies sites with no
success.
