So, when Diana and I decided to leave the Roger Henry for a couple days for a visit to the mainland, we went through our usual routine. Diana shut off the heater and the diesel fuel supply. She closed the thru-hull valves in the head and under the galley. I checked the dock lines for chafe and tension, secured loose equipment on deck, tied off the halyards, coiled the dock hose, and disconnected the shore power. We locked the boat and left a flashlight in the cockpit in order to see the combination should we return in the dark. We notified our neighbor of our plans and headed down the dock without a worry in the world.
