Why this word is great

SEAFARING — [Adjective, Noun] Describing a life, vessel, or person associated with travel or work on the sea; as a noun, the practice or profession of traveling by sea. From Middle English, a compound of sea + faring (present participle of faren, "to journey, go"), from Old English fær ("journey, expedition"). Cognate with Dutch zeevarend and German seefahrend. Unlike "maritime," which pertains broadly to all things of the sea and its commerce, or "nautical," which deals in the technical specifics of ships and navigation, seafaring is the active, lived reality of departure and vocation. It is the salt-stiffened wool of a sailor's jersey, the hypnotic watch of stars over an empty night swell, and the peculiar loneliness of a light seen from a ship at night—a chronicle of a life defined not by the land it leaves, but by the perpetual, horizon-chasing condition of being between.

adj

Living one's life at sea.“There was absolutely nothing about the body to suggest that it might possibly in life have known a maritime experience. It was the body of a low type of man or a high type of beast. In neither instance would it have been of a seafaring race. Therefore I deduced that it was native to Caprona--that it lived inland, and that it had fallen or been hurled from the cliffs above.”
Fit to travel on the sea; seagoing.“A rowing boat is not a seafaring craft.”

noun

The act, process, or practice of travelling the seas, such as by sailing or steaming.
The work or calling of a seafarer, especially a sailor.
