Definition of "whalesman"

The old whalesman was not long aboard before getting confirmed in his conjecture that the ship was the same whose boats had harpooned and “drogued” the cachalot', the carcass of which had been encountered by the Catamaran.

1865, Mayne Reid, The Ocean Waifs: A Story of Adventure on Land and Sea, page 363

Take heed young whalesmen and listen to my word.

2011, Frank Rogers, The God of Shattered Glass, page 224

That's the distinction your heroic whalesman made about us fishermen, just because he thought the whale's brain enlightened the world while we brayed like asses about the hard life we led. So I say a whalesman is to a fisherman as a gold-digger is to a quarryman.
