Dan i dont plan to glass above chine. Actually i worry if any structural problem occur if i dont renew the neat epoxy before primer.
Well, you asked me. I gave my opinion.

Both Matt Gent and Cowbro are having issues with unsheathed ply. It is basically a week's work for insurance against paint issues later.

Any epoxy coating is NOT considered structural. If you sanded through glass below waterlines; those must be repaired with glass and epoxy.

Good luck. The boat looks like it is coming along nicely.

Fairing is a pain.

What is your name?

Good luck to you too. Eventhough you dont need it.

Good luck with the flip. You'll be amazed with the size of the boat after the turnover. Mine sure seemed bigger when I was looking at the inside of the hull.

Hello again,

I started laying tapes and next laying to the fabric inside of the hull.

Should the fabric cover also top of butt blocks? Or are those areas negligible?

If butt blocks are allowed, then they should be made in such fashion that allows for laminating over them I'd say. This is a Gatehouse design, iirc, so it would be best to ask him. If your butt blocks are not too thick, you would be able to fillet a triangle to get to them, but I encourage you to hear from the designer first.

Butt blocks are not usually used on boats the size of the HMD. Instead 6" biaxial tape is used on all the seams. It is as strong and allows for smoother lay out of the 12oz biax cloth.
