HANDY HINTS 

 

It is a common error to locate the windlass too far forward, or too close to the bulk head, where there is 
insufficient room for chain and anchor stowage. The chain fall should be positioned in the centre of the 
chain locker to maximise the fall of the chain. If the chain falls alongside a bulkhead or onto the stem it will 
typically pyramid and jam. 
If the windlass requires positioning such that chain falls into an undesirable position, a metal tube can be 
fitted under the hawser to redirect the chain to a preferred position. This pipe should be at least 2 times the 
diameter of the chain. It should also be as vertical as possible. Position the windlass in the best location with 
the chain hawser facing forward.  
Ensure sufficient room to run electric cables to the windlass. Follow the installation instructions, including 
underdeck stiffening, deck camber, alignment, mounting blocks and sealing procedures. The gearbox and 
motor can be located in one of 8 positions.  

 

ELECTRICAL

 

 

See Wiring Diagrams for  wiring instructions. 

 

Circuit breaker

 (must be fitted to ensure warranty) 

If the windlass is overloaded or stalled the circuit breaker will automatically cut power to the windlass and 
protect the wiring and motor. The circuit breaker should not be used as an isolating switch. 

 

Deck Switches

 are best located out to either port or starboard or directly behind the windlass in a position 

where it can be easily reached with your foot or knee, preferably where you can view the anchor and chain 
coming aboard. 

 

Isolating Switch 

should be fitted in an accessible position for safety, ideally close to the battery or switches. 

The isolating switch is not a circuit breaker. 

 

Batteries

 are best located as close to the windlass as possible. Larger cables will reduce the voltage 

drop to the motor and the heat generated when running the windlass. Small diameter cables drop 
voltage considerably. Use the following table as a guide to your required wire size:

Rotation

:

 Windlasses may be wired for single or dual direction, using single or dual deck switches for raising 

or lowering. Alternatively a remote control solenoid package with Toggle Switch, Hand Pendant or Auto 
Anchors are available.

WARNING: Keep solenoid away from salt and fresh water 

 

Solenoid Installation

 

 

We recommend that the solenoid is installed in an 
upright position, where it has 

no exposure

 to sea 

water and in close proximity to the electric motor 
of the windlass.  

 

Do not place the solenoid in the chain locker. 

 

For wiring information, please refer to the 
appropriate wiring diagram listed in the table 
below.
