This image shows the now-loaded boat, with the lobster traps (known as pots) stacked on the top, as the lobsterman prepares to push off into the water.
The description states simply: OFF TO SET THE LOBSTER TRAPS
–There appear to be only two traps on board as the lobsterman pushes off, so this is a modest endeavor at best. It seems probable that the same trip will result in bringing back full traps when these are placed.
