Sorry if this was already discussed, I searched, but didn’t see anything in a quick scan.
I also just posted these pix in my build thread, but wanted to also post in a separate thread for a little more exposure and opinions.

Any thoughts on using epoxy with a layer of 24oz woven roving (no mat, (2400 if you will)) to laminate two pieces of 3/4” Coosa Bluewater 26 together in an otherwise vinylester build?

I feel like the only epoxy the vinylester will “see” is a very tiny line in between the two layers. The adhesive and strength qualities of epoxy interested me in the critical, high stress area of the “knees” that tie the transom to the hull and first bulkhead. The plan is to tab and wrap the 1-1/2” thick Coosa knees with enough 1708 and vinylester to achieve the fairly substantial original thickness. (I forget what that is at the moment, my notes are elsewhere, 3/8 or 1/2?).
Of course I will radius the top edges to let the 1708 conform.

Photos attached for reference (ignore the cut up boat, it’s not the one I’m working on, but the same make/model)

Thanks!!

Glass Dave said to use 1700 with the vinyl ester resin. The 1700 is woven and with out any mat. Really soak the board when bonding them together. Not a glass expert but passing along what Guru told me. Good luck.

Dave said the 1700 is stronger than the 1708 and easier to use for laying. He showed me how to use the peel ply, cuts down on sanding and leaves a nice finish.

Thanks Drake!

I spoke with him too, and he recommended a similar schedule for my transom. I’m using 2400 (a tad heavier than 1700) to sandwich between the marine plywood transom layers.

I’ve got a fair bit of Epoxy, so I decided to use it here in the knee build, since it will only be between coosa board layers and nearly invisible to the vinylester I will use to tab and cover them.
