I visited with CLC boats last weekend at the Port Aransas wooden boat festival to look over the prototype teardrop camper and pick up any tips on their construction. I saw that there was slight delimitation of the galley flat at the joint with the bulkhead (about a fingernail width crack). They had added a pair of metal braces (very nice looking) to reinforce the joint. Got a picture of the teardrop, but didn’t get a closeup of their galley flat / bulkhead joint.
Added one layer of 3 inch fiberglass tape to the galley side of the galley flat/bulkhead joint. I have painted two layers of fiberglass over the tape and will sand it prior to varnishing to make it a little less visible.
Here is the interior. I have added two layers of fiberglass tape (one 4 inch wide strip and one 3 inch wide strips). This should be plenty strong.
