Waterman is a term used to describe someone who is involved in activities that require a great deal of time spent out on the water, such as fishermen, sailors, or boatmen. Synonyms for the word waterman include seafarer, sailor, mariner, boatman, skipper, fisherman, angler, and navigator. Each of these words carries its own connotation and nuance, but they all share a common bond of an affinity for the water and the skills necessary to navigate and work upon it. Whether you're a saltwater aficionado or simply enjoy the calm and serenity of a lake, if you feel at home on the water, it would be fair to call yourself a waterman in one way or another.
