I remember reading about the material that the 9 x 3 x 3/4 in piece (attached pic, but not sure where it went to) that slides into the aft end of the bowsprit is made of. I did a lot of searches, but did not find any references to it.
Anyway, besides not knowing what to call this item, I don't know what it is made of. It appears to be a sandwich of two pieces of a ceramic-like material that was wrapped with some other material to make it more durable to the elements. My piece fell victim to UV or other degradation, and the coating is well "worn off." Where the inner material is exposed to the elements, it seemed to have a significantly chalky, as if oxidized. When scrubbed clean, the chalky coating is gone, and there is significant erosion of the inner material.
Two questions for the community:
1) What is this material, and where would I find it to replace the piece on Finesse?
2) If unavailable, what is a substitute material? This part carries sheer loading, so something like acetal (Delrin) might be a reasonable choice. Sun exposure is a problem for plastics, though.
Thanks for your ideas and inputs. If anyone knows what the outside coating is, I might be able to recoat this piece where the sun hits it. The coating is intact where the wood covers it.
