We use a horizontally oriented windlass on our Race Committee boat, with all chain to a plow anchor. It feeds in or out without having to have anyone on the foredeck, with no override issues. This has been useful when we've held races in four to six foot waves. Not having used a vertical one, I don't know, but does someone have to tail the line and feed it into its locker with a vertical windlass? If people are dragging down on you and you have to pull the anchor on a rough night, it might be safer not to need someone on the foredeck tending the line.
