Nautical Glossary

The maritime world uses a vocabulary that mystifies the layman for its obscurity. Below is a list in alphabetical order of terms used in the Royal Navy
and their Explanations, obtained from Wikipedia (see also its Glossary of Nautical Terms), the Age of Sail, David Steel's The Elements and Practice of Rigging And Seamanship (1794), the Textbook of Seamanship (1891) by Commodore Stephen Bleecker Luce, and other sources.

Explanatory words in italics have their own entries under Term, while Image Sources in  grey  indicate cross-references to other Terms.
For space considerations, some Image Sources are abbreviated (*), but given in full at the bottom of this page. Reliable source attribution is rather problematic because a given image may be shared by many sites, not always bothering to indicate authorship.
