Start with the axis
Smith describes a substantial upright piece of timber worked with bars. Falconer’s later dictionary likewise explains the capstan as a column whose bars allow people to turn it horizontally. For the windlass, Falconer describes a horizontal timber supported at its ends. [1][2]
That is the quickest visual distinction. A wheel-like or cylindrical object on a deck should be identified through its axis, connections and work rather than assumed to be steering equipment.
Leverage turns many efforts into one movement
Bars give the workers a way to apply force at a distance from the axis. Rope or cable then connects that turning motion to the load. The machine organizes human effort; it does not remove the need for people or make a heavy object weightless.
Smith lists several possible capstan tasks, including moving anchors, spars and other heavy equipment. The load and arrangement change, while the basic purpose remains applying a coordinated effort. [1]
Holding the gain matters
Both descriptions include pawls intended to resist backward movement. A heavy load could otherwise undo the work or drive the mechanism back. These stopping features are part of understanding the machine, not incidental decoration. [1][2]
The ship also needs room for workers and a clear path for the cable. A diagram that shows only the central timber leaves much of the working system invisible.
The installation depended on the craft
Smith mentions a windlass in a longboat, while Falconer places the larger horizontal machine in merchant-ship anchor work. These descriptions show a family of applications rather than one universal deck layout. [1][2]
A particular pirate vessel might have been captured, altered or repaired. Its apparatus must be established from evidence for that hull and date, especially before drawing an exact arrangement.
Read it beside the anchor and the boat
The anchor supplied a hold, the cable transmitted a load, and the machine helped the crew handle it. Boats could perform work outside the reach of the principal vessel. Keeping those parts together explains more than a list of isolated nautical terms.
Continue with anchors and cables, the work of boats and the ropes above the deck. This is an explanation of historical machinery, not instructions for operating it.
Questions, answered.
Is a capstan the ship’s steering wheel?
No. It is a hauling machine; steering uses a different mechanical connection to the rudder.
What is the simplest distinction between capstan and windlass?
A capstan’s main axis is vertical; a windlass’s is horizontal. Actual designs and uses require a vessel and period context.

Entries “Capstern, or Capstan” and “Windlass.” The dictionary is dated 1769 and describes a later technical setting, not the equipment list of every earlier pirate vessel. Published 1769, later than most events in this chapter. Used as a dated terminology comparison, not proof that an earlier pirate carried a particular instrument or followed later naval regulations.
