transom repair question

[FELLOW-SHIP]

When I did my transom I didn’t find any water but it did get thin after I finished removing the plywood and cleaning it up. I built it up to over ¼” thick before I added any new plywood. If I were going to use the new composites material I would go up to 3/8” thick. When I go to boat shows and look at the transom blocks that most boat builders show the public their outer skin is approx 3/8” thick and the inner skin is approx ¼” thick.
