With precurving and DER the hand laying would be reduced to the bulkheads and the lower bow. DERs would also reduce drag
I like the ease of moulds. Just a couple of saw horses and a couple of pieces of timber clamped together. I can see where nesting and reducing later joins could be improved, especially with a slightly longer table.
Don't know how you are going to seal the hatch and provide ingress without special tools. I suppose a hinge on the bottom and a couple of handles at the top could do it, or some tabs on the inside rotated into slots with a couple of handles on the outside to provide some torque
