DRIFT LEAD

A lead placed on the bottom to indicate movement of a vessel. At anchor the lead line is usually secured to the rail with a little slack and if the ship drags anchor, the line tends forward. A drift lead is also used to indicate when a vessel coming to anchor is dead in the water or when it is moving astern. A drift lead can be used to indicate current if a ship is dead in the water.

CHANNELS

FOURTH RATE

In the British Royal Navy, a fourth rate was, during the first half of the 18th century, a ship of the line mounting from 46 up to 60 guns.

CHASE PIECE

A cannon pointing forward or aft, often of longer range than other guns. Those on the bow (bow chaser) were used to fire upon a ship ahead, while those on the rear (stern chaser) were used to ward off pursuing vessels. Unlike guns pointing to the side, chasers could be brought to bear in a chase without slowing.
