    The fast path to performance! Tacking will never be the same. The Grinder patented four-speed winch allows you to let off the old sheet during a tack and sheet in the new sheet quicker than two could perform the operation with a standard two-speed winch. The Grinder is that revolutionary--it changes how you tack: preload the new winch and crank. It's that simple and quick. The first revolution of the winch brings in over two feet of line--an astonishing feat. Reverse the direction for more power. Repeat twice, gaining more power each time.

    Grinder Winch Features:

    • Mechanical advantage of additional gears allows you to sheet in 6-times faster than a two-speed winch
    • Safety—no struggling with a whipping slack sheet
    • Four speeds—engaged with easy-to-understand reversing of the winch handle
    • Automatic load detection on winch drum
