I have an electric windlass in the anchor locker, mounted on a plinth. Even though it is on a plinth, and the locker lid just closes onto the windlass, the locker is not deep enough to allow for sufficient drop of chain. You need to sweep the chain forward into the well as it comes up to avoid the windlass jamming on the chain. The only way round it is to somehow mount it on the deck but even then I do not think the drop in height will be sufficient to negate sweeping it.
