With the poop deck frames inplace, Sandra and Gina secure the deck plate, and cut out and install the metal aft bulkhead. Taking advantage of a rare winter warm spell they attach the cabin side plates and install the pilot house frames, cabin rooftop and cockpit frames. When spring finally arrives, they pull back the tarp and add split pipe to round off the pilot house and cabin side edges. Then they proceed with the cabin top and pilot house roof, decide on the best design for steps up to the poop deck, and use more split pipe to round off the cockpit coaming--no sharp lines for this yacht! The episode concludes with adjusting the transom to fit an unplanned curved swim platform and remembering to lower the engine below before closing up the hull.
