Sandra and Gina start welding up the hull, learning more tricks to keep the hull shape fare. They check all the welds and grind them smooth, fighting off spring rains. With the hull plate finished, it's finally time to roll the hull over. After fabricating their own boat stands, they secure a giant crane for the big day. With the hull right-side up, they cut out deck stringers and frames, and install and fare the forward decks. Then they cut and fit the poop deck frames, fabricate and fit the transom, and discover just how big their boat really is.
