My chain locker drains directly into the bilge--problem solved. The tiny bit of water that gets into the chain locker when retrieving and washing down the chain and rode is almost insignificant--probably less than a cup or two at most. The bigger problem is the open hawse pipe, which can allow a fair amount of water to enter the chain locker when a wave washes over the bow. While this rarely happens, the volume of water is fairly significant. I solved the problem by cutting a 1/2-inch thick slab of gum rubber to fit the hawse pipe opening, cut a slot for the chain that fits tightly around a single link, and even a heavy wave just washes down the gunwales without dumping anything into the chain locker. When I'm ready to deploy the anchor, I remove the rubber insert and press the winch button--it's that easy.
