In the movie Pirates of the Caribbean: The Curse of the Black Pearl, Capt. Jack Sparrow and his crew snuck up on their enemies by submerging an upturned wooden rowboat and breathing in an air pocket in the upside-down boat's cavity. What stupidly large force would be needed to hold such a boat underwater? The total volume of the wood is 0.0644 m3 and the density of the boat is 380. kg/m3. It will hold 5.36 m3 of air which has a density of 1.20 kg/m3. The density of water is 1000. kg/m3.
