Tosca gets a windlass

Here is a photo of the windlass installation on our Y-33. The windlass was a really good addition to the boat, second only to the diesel heater according to the Admiral. If we didn't get a good set it was easy-peasy to pick it up and try again. It was getting harder and harder to do that 2-3 times and this takes the huff and puff out of anchoring.

The windlass is a Maxwell RC8-8. The design/engineering process was a bit convoluted. I devised a spurling pipe to feed the rode down below the v-berth, but it got more and more complicated to get it to fall fairly. There's another thread on that topic. After trying multiple times and failing, I capped the spurling pipe off. The goal was to raise and lower the anchor from the cockpit while at the tiller, but that will have to wait.

The windlass drops the rode into the anchor locker, which is entirely too shallow. I'm using an inexpensive wireless winch remote on a key bracelet, so I can reach in under the windlass and pull the rode back while operating the windlass. I have a spare remote solenoid and fob ready if (or more likely when) the el cheapo Amazon remote dies. We used it for a 3 week trip to Barkley Sound and it worked great. There was a learning curve but we retained all our digits and appendages.

I wired it with 2 AWG cable, which according to the manual is acceptable for 48'. It would have made sense to go one size bigger, but pulling bigger cable might not have been possible. The cabling runs through the lockers behind the settee, through the head, then up into the overhead over the v-berth to the anchor locker. The turn from behind the medicine locker in the head to the v-berth is the choke point. The solenoid is mounted to the side of the anchor locker.

The windlass mount plate and anchor locker hatch are made from two layers of 1/2" Coosa board laminated top, bottom and between with 10 oz glass and Resin Research epoxy. Another 2 layers of 1706 biax were laminated to the underside of the plate under the windlass. I used this project as an excuse to try vacuum bagging and it worked really well. The through-bolt holes were epoxy filled and drilled, more for strength than water intrusion, as the Coosa board is impervious to water but it's a foam-fiberglass matrix and not particularly impact resistant.

I already had some paint matched to the gelcoat but it flashed off in the heat (it was over 100° in Boise when I did this) and I didn't have enough to finish the hatch. It doesn't fit very well, but it's temporary. I plan to install the original hatch over the top for a better look. It will take some glass fabrication and skid pattern matching. A project for this winter.

Nice write up @mermike. Really makes you ready to take on the Salish Sea.

Very cool! The previous owners of my Y33 installed a windlass just forward of the anchor locker, which I always thought was a terrible idea... because it was near impossible to get at from inside (the windlass was removed in 2020).

This is a much better solution. I saw something similar last summer on another Y33.

We also made our out of coosa board! I'm running 4ga wire from the solenoid to the engine battery today. Do I wire it to my on/off switch, directly to the battery, or to the bus bars I have after the keyswitch?

Thank you for your excellent post!

Great job & write-up!
I Installed a Lewmar V2 windlass on my boat; one of the more difficult projects that I have done.

I wired mine from the house bank to the windlass breaker and then to the solenoid which is mounted in the bow. My house bank is 2 200AH LFP batteries charged by the alternator.

There are many ways to wire a windlass. This worked best for my setup. The mfr will have a recommendation in the manual for cable size depending on the round trip distance. Make sure your cable meets the spec. 4 AWG sounds small to me.

I ran 30ft to the engine battery.
Cable length is measured round-trip, from the battery to the windlass and back. 4 AWG works if a 5% voltage drop is within acceptable limits. If 30' is one way, then you need 2 AWG.

Windlass mfr's recommend you connect the windlass to whichever bank is charged by the engine.


You must have a shallow anchor locker like I do. The raised mount looks like it solves the problem.
