I'm with Yacht rigger on this one - get up there and esnure that the sides of the
hull are tabbed with glass to the deck, glue alone is not good enough for point loads and Parlay Revival has me spooked about production cat bow decks.
It is not a tricky job technically but access could be difficult. A small angle grinder or even an file sander could get the
gelcoat and
paint off the corner angke so you can cove and glass with 2 layers of 440gm 100mm wide double bias tape. Glue in a G10 backing plate afterwards and you will be fine to install a padeye. I would use
epoxy because I like it - no one is going to see the job and epoxy will have better adhesion.
This is the type of tool I use for hard to access places - just get a
cheap powered one instead of a high quality cordless one.
