In the past, I used two deck brushes when scrubbing the boat with soap and water after a day of fishing. A brush with soft bristles covered 95 percent of the boat, but I had a stiff-bristle brush standing by for stubborn spots of dried blood and tracked-in dirt on the deck. Today I use only one brush — the Combo Deck Brush from Shurhold (about $34). A ring of long, soft bristles cleans most of the deck and the smooth fiberglass surfaces, while a core of short, tough fibers rests in the center. I deploy these stiffer bristles simply by pressing down on the brush when I need the extra scrubbing power. Combine this brush with a Shurhold 9-foot telescoping aluminum handle (about $38), and you can wash just about every spot on your boat with one tool.
