Thanks so much for the follow up and your interest. I think there were only two areas affected, one was about 8 inches square and the other about 4x12 inches. In both cases I think it was the fill coat only. I scraped down to the cloth and used some lacquer thinner and I think I got off all the soft epoxy. I think I'm going to get away without removing the fiberglass cloth layer. I have lightly sanded the entire boat and was going to add a final coat of epoxy to smooth out the surface and fill a few areas of mesh that were not completely filled initially. I had asked the question on the forum (but no reply so far) as to whether it would be advisable to thin the final epoxy coat with some lacquer thinner to help it flow out and level better. (There were a fair number of drips and bubbles in the last coat, which did not become obvious until I sanded) (120 grit, random orbit).

I did locate and drill Moroske holes and have taped and filled them with epoxy/wood dust mixture, prior to the last epoxy coat, and will re-drill after this last coat is done. I was going to cut out a hatch after the epoxy coating is complete. Once I remove the deck from the forms and can get to the underside I will make the Moroske channels with the tubing, as you have so nicely shown in your photos.

I still have the deck on the forms but the hull is glassed inside and out and is off the forms, and I will have to join hull to deck later. I have purchased the foot braces and a foam seat which I will install in the hull prior to joining deck to hull, for access. I also got a sheet of the marine microcell foam which I was going to use for a bulkhead (maybe lighter weight than wood)

All comments/suggestions welcome. Thanks,
Jay
