Sandra and Gina build a gantry for the chain hoist they'll need to lift steel plates, then start serving up radius curved stringers, bottom and side plate, and more plate to cover the keel. Learning as they go, they discover new tricks to keep welds straight and bend heavy steel into the graceful curves befitting their dream yacht. By the end of the episode they've finished plating the hull and primed it red just as winter snows stop work until Spring.
