The action of grinding and tailing must be performed when operating a winch. Grinding is the movement of the winch handle, sometimes in a complete circle and sometimes back and forth from the 1 o’clock to the 5 o’clock position. This movement rotates the barrel of the winch, also in a clockwise direction, and provides the mechanical advantage. When grinding the winch, tension must be kept on the line that is coming off the winch, known as tailing. Tailing ensures that the wraps have sufficient friction against the barrel of the winch. Some winches have an additional piece of hardware on top of the winch known as the self-tailer, which grips and tails the line without needing to hold the line for tension.
WINCH HANDLE
Some winch handles have a lock-in mechanism which must be activated before the handle can be inserted or removed from the winch. A winch handle (even one with a lock-in mechanism) should not be left in the winch unattended. Nor should it be placed on the cabin top or the cockpit seat and floor. Remove the wind handle from the winch and place it in the winch handle pocket each time after using a winch handle. While there are a few winch handles that float, most do not!
WIND
When using a self-tailing winch, the line must be led over the prefeeder before leading it into the self-tailing grooves.
