Abstract
A low drag buoy uses diameter reductions and spoilers of a buoyant body surface to reduce the drag. An end structure at one end of a buoyant body allows connection of that end to a line, and a number of different diameter portions are provided between the ends of the body, a step reduction in diameter being provided at a juncture between each of the different diameter portions. A spoiler is provided on the larger diameter portion at each juncture, the spoiler typically being a flipper extending circumferentially outwardly from the larger diameter portion at each juncture, with a ramp surface leading from the body to the flipper, and a substantially flat and radially extending surface of the flipper opposite the ramp. The flipper typically extends outwardly from the body about 0.04-0.08 inches, and the step reduction at each of the junctures (not counting the flipper) is about 0.1-0.125 inches. The body may have a generally ovoid, cylindrical, or other body of revolution configuration. A number of longitudinal ribs may also be disposed on the body, upstanding from it, and may provide reduced spinning and increased stability for the buoy if pulled along the surface of water from its first end.
