A3_5 Oh Buoy

Abstract

As always, films are a great place to look for physical inaccuracies and impossibilities. One such film is Disney's 'Pirates of the Caribbean', where they walk underwater within a capsized row boat. From resolving the buoyancy and weight forces, the resultant force is 13230 N opposing the force of weight, which will act to push the boat up to the surface. From this we conclude that it is not possible for them to be able to traverse underwater in this fashion.
