Since starting at the beginning usually makes sense, let us begin with the letter A. Most of us know the terms adrift and afloat, and an equally large number understand the word aground. Many of us understand abaft (just behind; abutting behind) and athwartships (across the beam of the boat). Fewer of us, I’m sure, would profess familiarity with some of the terms used to describe the finer points of executing one of boating’s most common and most important tasks. I’m referring, of course, to anchoring.
