While lying in the v-berth I chanced to look up at the underside of the deck and thought about all those nuts up there with all their sharp edges. They would not feel good grating across your scalp in a wildly pitching boat. I ended up buying some stickon furniture leg buttons, the felt type with the super sticky back. I punched 3/8 inch holes in the center of each using a piece of metal tubing about that diameter and filing an edge alone its outside circumference on one end. By placing each felt button on a block of wood I was able to hammer the tube cookie cutter style through each one. It is then a simple matter to peel the backing and place each felt "donut" around each protruding nut. This not only protects your head from the metal nut but with the hole in the felt you can see instantly if the bolt/nut combination has started to leak. Another "back scratcher" I accidentally found on board was the forward end of the main hatch. Stand up too quickly to get into the cockpit and you risk mashing your backside on that edge. Here I took a small "pool noodle" although foam pipe insulation will work too and will not protrude down into the cabin as far, I sliced a one inch section out of it with a sharp knife leaving a foam channel which can be contact cemented around the perimeter of the main hatch inside the cabin. Just one less thing to bang your head or back on in confined quarters. Both projects are quick but will take a cold night up north to do if you dress yourself warmly.
