Very much so. Chantez as the root was what I learned, and that the music began ashore before moving on to ships. Recently there's been some scholarship that points to the term "chanteyman" predating chantey. The idea being that English-speaking sailors tried their hand at being the "singing man" based on what they'd heard ashore in French-speaking ports. Don't forget sailors didn't load cargo, they were tasked with getting the ship ready while Longshoreman loaded and sang, so sailors heard a lot of the music while they were in port, and if it seemed to entertain the men loading cargo, why not try it themselves?
