Pump well
Arguably one of the most critical pieces of equipment on a ship, the pumps on the Belle were of a simple plunger variety carved out of elm, a straight-growing, durable wood that carpenters of the day often chose for pumps. A lead strainer affixed to the bottom of the pump prevented debris from clogging the tube.
