Well, I called every place that I could find on Google in my area and none of them carry divinycell or balsa in 3/8". Looks like I'm going to have to order it from somewhere or drive out of my area to pick it up. Anyone know a place in SW Florida that carries, or can order, core materials?

As far as extra support for the bow area(cleat, anchor roller, etc.) I was going to mount epoxy coated plywood underneath the bow cap area. Similar to how Dennis did it: http://www.classicseacraft.com/commu...anchor+bracket

Ended up ordering a 3/8" piece of scored divinycell.
I also decided to switch from epoxy to vinylester resin for this project.

The plan has evolved to the following:

I'll sand down everything and bevel out the existing fiberglass 12:1 along all the edges.

I'll patch any holes in the bottom skin, possibly even laminate a fresh layer or two of 6oz depending how flimsy it feels after I sand it. I'll let all that dry and then re-prep the area.

I'll laminate a layer of 6oz cloth on the bottom of the divinycell and then while it's still tacky glue it down with a layer of Fasco 110 applied with a caulking tube. I'll weight it down on the top overnight while it dries.

The next day I'll trowl down cabosil into the scoring and along the edges so that its nice and smooth. Then I'll laminate 3-4 layers of 1708. I'll let that dry overnight.

Then I'll put a layer of fairing compound over the whole thing, let that dry, sand it down and paint it. At this point I will also mount plywood on the underside of the bow area to support the anchor hardware.

I'm not sure what else to use to cover the fiberglass itself, I am eventually going to paint the boat so doing a gelcoat didn't seem like the right thing to do.

I'll post pics as I make progress.

I order to make it look good you should fair it out with fairing compound and then throw a cheap coat of paint over it.

I don't know where you are getting your supplies out, but since you are in sw fla. check out

There is no core under the bow cleats. It's solid glass, ~ 1/4" thick. I added 1/2" thick plywood under those cleats and then a couple layers of 5/16 plywood reinforcement, approx. 15x15 under bow area including under the cleats when I added anchor bracket.

That would make sense, structurally. I can't tell what is going on in the picture supplied- he mentioned rot- and it looked like there was wood in there? Or is that some sort of delamination?

Default Core

There was a 3/8" balsa core between two layers of glass which extended from 4-5" below the hatch to 2-3" from the hull. There was significant rot(some areas were completely gone).

I think after I get the new core in I will build up some reinforcement like Dennis did.

I also am going to coat the inside of any holes I cut with epoxy. I don't think the divinycell, being a synthetic, will be affected by water, but I still don't want any getting in.
