"Make and Break Harbour" is a song by the Canadian folk singer Stan Rogers, first recorded as the 11th track on the album Fogarty's Cove in 1976.
The one-piston style engine was an important piece of technology featured on inboard motors for small fishing vessels that dot the Atlantic Canadian coastline.
Rogers cites some of the reasons for the loss of tradition with lines such as "And the young folk don't stay with the fisherman's way/Long ago they all moved to the cities" and "Now I can see the big draggers that stirred up the bay/Leaving lobster traps smashed on the bottom/And they think it don't pay to respect the old ways/That make and break men have not forgotten".
"Make and Break Harbour" also has a commentary on the overfishing that happened with the introduction of fishing trawlers in Atlantic Canada.
These trawlers would not only destroy lobster traps as the lyrics above show, but would also overfish, and outfish the fisherman who remained with the one-piston engine.
