Here’s a handy little site, I’ll just let them describe themselves in the quote below.

When one is first learning boating, there seems to be an endless confusion of terms, procedures, and rules to be memorized. Many of these are critical to safety, and over the years boaters have invented various little mnemonics to help them navigate the complexities. This Web page is a collection of such mnemonics, most time-honored, but a few invented by the author of the page (Geoff Kuenning) to fill in the gaps where none were available.
