It depends on the amperage draw of the used windlass and the length of your supply cables ( they could add to the amp draw). Some solenoids get their negative source from the mounting bracket, others have a + and -terminal that completes the circuit for the pull in coil. I forgot to check if this one is for "continuous duty". Recommended I would think for an application like a windlass.
You need something with a continuous duty cycle. sometimes hauling up takes quite a while, at 1 ft per second, to haul 350 ft of rode takes, well, 350 seconds, so a continuous dty cycle of 10 to 40 seconds wont cut it.
A solenoid that is used for something like a starting motor is designed to pull in, and be released in say 5-15 seconds when the engine starts. In an application where the solenoid will be pulled in much longer- it must be able to withstand the additional heat I assume. "Continuous Duty". I have seen solenoids that had one set of windings to make a magnetic field to pull in the contactor and a second set of windings designed to hold in the contactor. Maybe CD is someting like this.
