MID-EIGHTEENTH CENTURY NAUTICAL TERMS
The following is a concise glossary of nautical terms as they are used in the middle of the eighteenth century. It is intended as a work of reference to accompany the Carlisle & Holbrooke series of naval adventure novels.
This glossary is not exhaustive; a more complete list can be found in Falconer’s Universal Dictionary of the Marine, first published in 1769. I have not counted the number of terms that Falconer has defined, but he fills 328 pages with English terms, followed by a further 83 pages of French translations. It is a monumental work.

Some of the usages of these terms have changed over the years, so this list should be used with caution when referring to periods before 1740 or after 1780.
Aback: Referring to a sail when the wind is striking it from the wrong side and its surface is pressed against the mast. This can be caused deliberately to manoeuvre the vessel or can occur accidentally when the vessel is likely to be out of control.
Abaft: A relative term meaning towards the rear part of a vessel.
Abeam: Perpendicular to the centreline of the vessel.
Acockbill: An anchor is said to be acockbill when it is at the cathead or bow and ready to be dropped. A yard is said to be acockbill when one yardarm is higher than the other.
Admiral: There are four grades of admiral, in order of seniority: admiral of the fleet, admiral, vice admiral and rear admiral. In addition, each admiral is distinguished by the colour of his flag, in order of seniority: red, white, blue. Thus, an officer is styled (for example): Admiral of the Blue. Officers progress through the grades of admiral by strict seniority as officers above them die or leave the active list.
Admiralty Court: Courts exercising jurisdiction over maritime matters, particularly the condemnation of prizes.
Aft: Has the same meaning as abaft.
Afterguard: Those men who are stationed in the aft part of the vessel to manage the aft sails.
Afore: A relative term meaning towards the forward part of a vessel.
Aground: The situation of a vessel when it is resting on the seabed. Usually, but not always, unintentionally.
A-hull: The situation of a vessel when all her sails are furled to reduce the impact of the wind. Like lying-to but with no sails set.
A-lee: The situation of the helm when it is moved to the lee side of the vessel, usually to put the vessel about or turn to windward.
Aloft: A relative term meaning anywhere above the lower rigging.
Alongside: Fastened parallel to another vessel or a jetty.
Amidships: The middle part of a vessel, either bow to stern or side to side.

Athwart: Across the centreline of a vessel or across an imaginary line extending ahead or astern of the vessel.
Avast: An order to stop or hold.

Bear up: The same as bear away. There is much confusion over these two terms.
Beat: The act of moving to windward by taking a zig-zag course with the wind first on one bow then on the other, so that the vessel is always sailing close-hauled but never attempts to sail directly into the wind.
Beat to quarters: Beating a drum to command the crew to go to their allocated stations in anticipation of action against the enemy. Beat to quarters is still an appropriate term even when there is no drum available.

Dividers: A two-armed, hinged instrument used for measuring distances on a sea chart.
Dogwatch: The pair of two-hour watches running from 4.00 pm to 6.00 pm (the first dogwatch) and from 6.00 pm to 8.00 pm (the last dogwatch). They are intended to break up the four-hour watch system so that a man has a different sequence of watches each day.

Lasking: Sailing large with a quartering wind.
Lateen: A loose-footed sail set fore-and-aft on a diagonal yard. Until the late eighteenth-century all men-of-war had a lateen mizzen sail.

Above the topmasts are the topgallant masts (fore topgallant mast, main topgallant mast, mizzen topgallant mast). Some ships have royal masts above the topgallants but that is unusual for men-of-war of this period.
