In the time of the great sailing ships, on days where the sea was flat and winds were calm, the crew was fed a steady diet of beans and franks. When the urge hit to fart, they would run to the rear of the ship and fart to stern.
It also explains the meaning of the term "poop deck", since many farts turned out to be more substantial.
