Sailboat chain stopper Srew Type

for boat

The chain stopper screw type is a deck-mounted device designed to hold and secure the anchor chain, transmitting chain tension to the hull and relieving the windlass from continuous stress.

Application
The chain stopper is installed on the deck between the windlass and the hawse pipe to hold the chain. After anchoring, the chain stopper transmits the anchor chain tension to the hull so the windlass is not under continuous load. When sailing, the stopper takes the weight of the anchor and part of the chain and restrains the anchor in the hawse barrel against the hull.

Design & Operation

• Type: Screw-type chain stopper providing positive clamping action.
• Clamping: Pair of clamping blocks that grip the anchor chain.
• Control: Control screw tightens or releases the clamping blocks simultaneously.
• Characteristic: More complex structure than some types, offering secure holding and reliable operation.
