    Load transfer is managed at the height of those 1" plywood floors. There's a large cleat across the transom at the floor height, epoxied and lag screwed to the transom. A corresponding cleat bonded and bolted to bulkhead 6. The back cockpit sole is epoxy bonded between those cleats, down to the plywood floors, and to the hull sides. The remaining loads are managed in the multiple layers of epoxy glass on the 6" 150mm of transom that projects above the cockpit sole to form the splash well. And that 6" is tied into the structure at either end by large fillets and continuous glass inside and out to the hull planking, and through the 5" by 1½" side decks. (125mm ×38mm)

    Hopefully that will suffice.

    So, the transom above the sole is like 8 feet wide by 6" high? 1.5" of plywood and some glass? Did you cover the top edges of the ply? That is where a lot of guys have had trouble with ply openining.

    Just curious. I started to look for a picture and gave up.

    Transom is 2¼" thick, built up of lumber. 20" tall (51cm), of which 6" projects above the sole -which isn't in yet. It's 9'11" (302cm) long, because the hull planking runs off the end.

    Did you wrap the top? Worst place for delam in ply boats is unglassed transom tops.

    Apologies @fallguy . There's no pictures yet, because I haven't done it yet. That is the plan.

    Tent was getting squished again. Took it off to redo it, grabbed a pic from a different perspective.

    I think I'll mount some jack plates, so I can seal the deck before I get outboards.

    And now the cost of jackpletes has gone up. 800 clams each! That's good Bedrock currency!
