A friend of mine let me paddle his high-end fiberglass kayak (an excellent boat) and I discovered the joys of a good, fiberglass seat as well.  He had an extra, and I asked if I could borrow it.

The pictures below show my attempts at taking a mold from it.  There is much work left to do:  grinding the edges, plussmoothing the surface with more epoxy mixed with fairing filler.  But soon enough I hope to have a mold I can use to make new seats for the TSC boats.
