Gypsy wheels on either a vertical or horizontal windlass provide for either chain or line to be engaged. The gypsy for line is termed a warping head,It is important that the gypsy match the chain size (i.e. the link pitch) closely. Even a small difference in link size or consistency can cause undue wear on the chainwheel and/or cause the chain to jump off the windlass when the winch is operating, particularly during payout, a runaway condition sometimes referred to as "water spouting" should it occur at high speed. 

Applicable chain Size: from Φ 12mm to Φ 97mm
