Now, we have a Lewmar vertical "windlass" that contains a rope/chain gypsy.
On top there is a drum which the literature calls a capstan. The rope/chain
splice move quite smoothly through the gypsy. Nothing needs to be
transferred to the capstan drum. We have had very little use for thr capstan
drum, though I suppose with suitable turning blocks it could be used to
hoist a bosun's chair..

I use the capstan if I'm hauling up a second anchor at the same time.
