Sorry for my ignorance meant cloth not Mat old habits die hard :)

when I replaced the transom on my boat it had 2 layers of 3/4 plywood. I replaced it with 3 layers of 1/2. I figured the extra layer of epoxy would help. Plus the thinner plywood follows the curve of the transom better.

for the transom in my Sea Ox project i'm using 1 3/4 treated kiln dried 26 ply plywood.

Do you meen 1 sheet of 3/4 or 1 3/4 in thick.

26 plys I'm thinking 1-3/4 inches thick.

some pic's

I used 2 layers of 1/2" and two layers of 3/8" all resined on all faces and edges, also resined with thickeners in between layers and screwed together.

1 solid 26 ply 1 3/4 piece of wood

Resin'd in between and all around...that's not going anywhere....fully encapsulated.....just make sure you do the same with every hole you drill in it and it will last longer than the glass around it. Good work.
