OPERATE WITH CONFIDENCE
Windlass Safety Guidelines
Safety at sea begins with proper equipment and correct anchoring technique. The following Muir Safety Guidelines outline best practices for operating your windlass and anchor system, ensuring reliable performance and safe anchoring in all conditions. Whether you’re a first-time user or an experienced skipper, these universal recommendations — alongside general guidance from the Australian Maritime Safety Authority — will help protect your vessel and gear while maintaining smooth, trouble-free operation.
GETTING STARTED
Before You Start: Windlass Selection & Installation
These Safety Guidelines start before you’re even on the water: safety begins with proper windlass selection and installation. A correctly specified and installed Muir anchor winch will provide years of reliable, trouble-free performance. If in doubt about windlass selection, use the Windlass Selection Guide or the Windlass Selection Tool, or visit Dealer Locations to contact your nearest Muir dealer or service agent.

Safety Tips and Guidelines
Eleven habits that keep your Muir anchoring system running safely and reliably, season after season.
Correct specification. Ensure the windlass is correctly specified and installed.
Chain stopper. Always use a chain stopper of the appropriate size in conjunction with the windlass.
Run the engine. Run the boat’s engine while raising or lowering the anchor to reduce battery drain and improve safety.
Motor toward the anchor. When retrieving the rode — never use the windlass to pull the boat forward.
Fouled anchor. Do not use the windlass to break it free. With the chain stopper taking the load, use the boat’s engine to dislodge it.
Never a bollard. Always engage a chain stopper, cleat, or bollard after anchoring to prevent gearbox or shaft damage.
Heavy weather. Use a snubber line or heavy stop from the chain directly to a bollard or fixed cleat.
Never a mooring point. Never use the windlass or chain stopper as a mooring point.
Isolator off. Always switch the isolator “OFF” before leaving the vessel.
Full stop first. Do not change windlass direction (up/down) without allowing it to come to a complete stop first.
Don’t rely on the windlass alone. Do not rely on the windlass alone to hold your vessel at anchor — always back it up with a chain stopper, cleat, or bollard, especially when leaving the vessel unattended.
WHY IT MATTERS
Understanding Your Chain Stopper
One rule threads through these Safety Guidelines more than any other: the chain stopper, not the windlass, holds your vessel at anchor.
A chain stopper (also called a chain compressor or devil’s claw) clamps the anchor chain and transfers the anchoring load away from the windlass gearbox and onto the deck structure. Windlasses are built to retrieve the anchor — not to hold your vessel against wind, current, or waves. That job belongs to the chain stopper. Always engage it once the anchor is set, and before leaving the vessel unattended.
COMMON QUESTIONS
Safety Guidelines FAQs
The questions we hear most often about these Safety Guidelines.
Why can't I use the windlass to pull my boat forward?
Windlasses are built to retrieve the anchor and rode, not to manoeuvre the vessel. Motor toward the anchor while retrieving — using the windlass to pull the boat forward can overload the gearbox and shaft.
What do I do if my anchor gets fouled?
Never use the windlass to break a fouled anchor free. With the chain stopper taking the load, use the boat’s engine to dislodge it instead.
Do I need a chain stopper if I have a windlass?
Yes. Windlasses aren’t designed to hold your vessel at anchor long-term — always engage a chain stopper, cleat, or bollard once the anchor is set, and especially before leaving the vessel unattended.
What should I do before leaving my boat unattended at anchor?
Switch the isolator “OFF” and confirm your chain stopper, cleat, or bollard — not the windlass — is taking the anchoring load
