Thanks Bob. She is a big-bucks mega-yacht to be sure. The plywood is just a Baltic Birch which has exterior glue $25, eight pieces of mahogany shoe for the gunwale $25, adhesive $12, miscellaneous pine/plywood for braces (free), two 1x4's of clear pine for the seats $10, hardware (oarlocks, screws, u-bolt) $35, 2-part epoxy and glass $150, and primer/paint $44.
You certainly could do it cheaper if you skip the 2-part epoxy. Most of the others who built them just coated the wood with preservative and then used regular exterior house paint on them. That saves almost half the cost of the dinghy, but I wanted to coat the hull with cloth and epoxy to make it last a bit longer.
The oars are just scrap and leftover epoxy, so no cost there.
The weather up here in Wisconsin has been so lousy that B is finally starting to warm up to the idea of selling this big ol' house and moving down to the condo in Orange Beach.
