I've had the same problem when painting a primer over WEST Sytems epoxy. I painted the whole boat (Bolger Junebug) before I realized it was never going to dry properly. I had to strip it all off and put on a coat of Interlux 2-part epoxy primer. I think it was called 404/414. The epoxy primer adhered tenaciously and the Brightsides I put over it dried just fine.
Why not use the sail with slides? You could still wrap the sail around the mast for storage. Then you have the option of adding a halyard and reef points at a later date.
I lived in Boca Raton until 1982. I remember a storm in 1978 that rained somewhere around 18" in 1 day. Our whole neighborhood was flooded. Fortunately we didn't get any water in our house. There was about 2 feet of water in the street in front of our house, I was able to snorkel in it. We rowed a small homemade boat all around the neighborhood.
I'm not sure why but I couldn't embed the link when I was logged in using Internet Explorer. I was able to do so with Chrome. I first found your video on youtube and copied the URL. I then typed my post and highlighted the "sailing with dolphins" text. I clicked on the link icon (the icon with a picture of a few links of chain). I pasted the URL in the appropriate field in the dialog box and then clicked OK. That's it.
Thanks for posting your video.

If you can guarantee that there will never be even the slightest break in the epoxy barrier then you might have a point. But I certainly wouldn't count on it. I think it also matters how deep the fastener is buried. I've had screws that worked a bit over time and cracked the epoxy covering them. Admittedly the epoxy layer was pretty thin. If these screws had been plain steel they would have rusted immediately.
