Back-Winch System

For jet boats or heavier boats your dock will include a Back-Winch system. A typical Back-Winch system is shown
above.

The Back-Winch system is a set of line and pulleys (blocks) that will help you move your boat to the stern of the dock for
easy removal. This is accomplished by running a line around the bow of the boat above the bow eye.

The concept is relatively simple. A line is looped over the bow-eye of the boat and then runs aft of the bow-eye through
a pair of blocks and each end of the line is run forward to the winch. When the winch is pulled tight, the line between the
winch and the back blocks is lengthened and the line from the bow-eye of the boat and the back blocks is shortened,
thus pulling the boat backwards.

The Back-Winch is installed so that when the line is pulled tight, the line through the back block is still slightly aft of the
bow eye and the transom is in the water. Typically the rear block is attached anywhere from 6 to 9 rows of floats behind
the front of the V-Berth, usually between the 7th and 8th row. Depending on the boat, some adjustment may be neces-
sary.
