62 Useful Nautical Terms That You Should Know

Some of these nautical terms will make you want to meet whoever could have possibly come up with some of these interesting words. These terms will cover the anatomy of a boat, directional sea terms, terms used while on a running boat and even a couple of slang terms for fun.

What Exactly Are “Nautical Terms”?

The phrase ‘Nautical Terms’ is relatively new. In the past, they were called ‘sailing terms’. Whatever the name, these words and phrases are simply associated with boats, ships and sailing. Like kitchen shorthand or terms specific to science, ex. ‘beaker’.

Some of these nautical terms can be rather silly; however, most really come in handy when speaking about boating. Whether they are new age or created back when ‘pirates’ were popular, they all have their own specific meaning. Knowing the difference can sometimes mean the difference between running aground, shipwrecking or smooth sailing.

Directional Sea Terms

Want to sound like a true seaman? Try some of these directional terms when running your vessel.

  1. Forward : This doesn’t reference the motion of the boat, but actually the motion of the people on the boat. When asked to go forward they are telling you to move towards the bow of the ship.
  2. Aft : The opposite of forward is backward. When asked to go aft, you are expected to make your way back towards the stern of the ship.
  3. Ahead : Now we are talking about the movement of the vessel. Ahead references the forward movement of the boat.
