Rather than using the hand-over-hand method of retrieving lines, the capstan offers a mechanical advantage that is both faster and safer. The capstan does the heavy lifting with only a small amount of effort. The maximum speed of the line retrieval depends on the rotational speed of the drum. The benefit is that the retrieval speed can be adjusted by decreasing the tension on the retrieved line, maintaining control over a very heavy load with little effort. This useful device, which has been around since the early days of sailing, is still used today. Recreational fishermen, like commercial fishermen, use these for hauling crab and lobster pots and there are many other uses aboard boats. The few mechanical parts and ease of use have made this a favorite of fisherman worldwide. While chains should NEVER be wrapped around a drum, the majority of lines can be handled on a capstan.
