Ethanol is reducing your engine's efficiency. Fuel prices are sure to rise. And, the way things are going, I'd bet fuel taxes spike as well. These things are out of your control, but you can combat them. Give your boat a "bottom job," and it will run faster and more efficiently. We took in an eight-year-old Aquasport, the bottom of which was pocked and cratered by years of uneven wear. After applying materials and using tech assistance from Interlux (www.yachtpaint.com, 800-468-7589), the hull surface wasn't just showroom smooth, it was better than new, since we fixed some manufacturing glitches in the process. You can get the same results with two weekends' work. The time required makes haul-out a good time to tackle this project, because you won't feel the pressure to launch that comes with spring. Just follow these steps.
