Glossary of Nautical Terms

A glossary of nautical terms provides an understanding of the language used in seafaring and navigation. It includes terminology related to ships, seamanship, and watercraft. These terms are vital for communication and ensure safety and efficiency at sea. Below is an exploration of some notable nautical terms, their meanings, and uses.
