Continuity mistake: When Max is phoning the Chief to let him know the mission's been accomplished, he takes the oars out of the oarlocks before opening his shoephone. The oars change from being out of the oarlocks in the closeups to still being in the water in the long shots for the rest of the episode.
Continuity mistake: When Max is attacking the boat there is a shot from inside the cabin. Watch the door. Before Max shoots, there are a series of holes in the shade covering the door (they look like bullet holes). Max begins firing and there is another shot from inside and bullet holes begin appearing in the walls. The holes in the shade however, are gone.
