While you don't need to be fluent in boating terminology to operate a boat or enjoy boating activities,  there will be times when you will wish you had at least a rudimentary knowledge.


While there are hundreds of nautical terms, some dating back to the 17th century, I shall only introduce you to some of the more common terms which you will encounter today.

Don't worry there is no quiz at the bottom. Some of the terms you probably already know and the rest will become yours with use.

I would appreciate some honest appraisals and suggestions as to how to improve it.
