A32 Electric Windlass Installation

Our thanks to Zsolt Kecskemeti for this article describing his installation of a Lewmar Horizon 900  electric windlass on his A32, "Water Music". Much of the advice would apply to installation of another make or model of windlass on a 32 or other model of Aloha.

Positioning the windlass involved a lot of scalp massage. It cannot go too far back, because the chain would go down next to the access door. Filling in the old chainpipe could be a pain. The gypsy cannot be centered, because the chain would come to it at an angle. The motor cannot be turned towards one side, because then the drum would be useless. The original rollers sit lower than the gunwale with the teak trim. The chain and the anchor stem would chew away that teak in no time, plus there is the extra friction to worry about when hauling in the anchor.

The solution is to line up the gypsy with the starboard roller. Place the motor between the old chainpipe and back of the anchor chamber. The chain is not going to slump against the door, and the drum end of the machine can be used to set a second anchor. By splitting the anchor chamber, the line of the second anchor could be fed down the old chainpipe.

To balance the asymmetry of the motor placement, the footswitches were moved to port.

I got 50 feet of chain spliced to 200 feet of line. The extra cleat serves two purposes. The anchor stem is pulled down to it, so the anchor sits very snugly in its place. Clanking eliminated! When the boat is at anchor, the anchor line is tied to this cleat rather than than the starboard bow cleat. This way the line is straight and cannot chafe on the back edge of the bow roller.

The teak was cut so the Kingston bow roller would sit on the fibreglass gunwale. Four bolts hold it, and the bottom outside corner is fastened with a bracket to the bowsprit. The holes on the bow roller cannot be used to secure the anchor with a pin. They are pretty decorations now.

The bracket that connects the new bow roller's corner to the old frame is T-shaped and bolted on both sides. The hook and the line pull the anchor back to the new cleat.

These are the backing plates in the anchor chamber. The smaller one is for the new cleat. I mixed epoxy with micro balloons to toothpaste consistency and buttered the top side of the plywood. The epoxy that oozed out was used to seal the edges of the plates. The bottom of the windlass got a layer of Sikkaflex.

The 2 gauge monster cables come to this solenoid from the battery compartment. This is how the cables were routed: battery compartment, bottom edge of engine bay door, under the fridge, under the stove, past the aft end of the water tanks, up into the storage behind the seats, through the hanging lockers closest to the gunwale, through the side storage compartments in the v-berth. Lots of drilling! Due to the bends, I needed 2x45 feet of cable. The thinner wires go to the motor and the switches.

The windlass can be operated with the foot switches on the foredeck or this rocker switch in the cockpit. Three wires connect the rocker switch to the solenoid in the anchor chamber.

The canvas cap goes under the drum, and clips under the chain. It keeps the rain away from the chain hole.
 
There is one more component I need to mention, an in-line thermal breaker for the heavy cable. I mounted this breaker on the outside of the engine box, to the left of the access door. It can be reached easily from the cockpit.
 
Everything works perfectly. The windlass has tremendous power and speed. It handles the anchor and the 50 feet of chain effortlessly. The total cost of the project was $2100.
