On deck, Sandra builds the hatch frames, hinges, and dogs to batten them down, then adds the Lexan lenses. She builds and installs several mushroom vents into the deck for ventilation, attaches safety hooks for harnesses in foul weather, cuts out the hole for the mast and adds parallel bung rails to support a crew member when hoisting the main, and adds aft port lights in the transom to let light and air into the rear cabin. Below decks Sandra and Gina install white vinyl paneling to the forward cabin then spray foam insulation in the rear cabin. Next they tackle the most complex construction project yet: fabricating and installing the steering system. This includes the rudder post and support, the rudder itself, the steering ram with its hydraulic pumps and lines for two steering stations, one in the cockpit and one in the pilot house. Finally, Sandra settles on the design for cockpit steering binnacle and begins fabrication.
