Boat shifter's on right, by beer can holder - ice chest full of beer is on left, upon which gunman sits with gunwale at right centre of boat. This positioning allows gunman to protect beer whilst rat-a-tat-ting up an even uh, keel of fire on skiiers of enemy watercraft, and occasionally, cheapskates who didn't follow the BYOB rule. Said cheapskates were ostensibly being taught to barefoot-ski (no need to retrieve skis, punctured tubes, etc. It's a messy business. Just pull in the ski rope. Next!) Pilot of watercraft remains able look over either shoulder at the carnage of a typical day at typical American lake, without concern that right-extracted hot shell casings from rearward facing machinegun will land on him, all the while keeping a lookout for Nessie, the Magic Water Dragon. If boat cap'n's flying solo, the more damage he can do to his liver with beer and other's liver's by bein' the rootinest-tootinest-shootinest on the Lake, the merrier!
