Jack Sparrow and his band of pirates are planning to board your vessel and force you to walk the plank.  The 50ft Black Pearl, written into pirate lore as one of the most formidable vessels ever to sail the open seas, has just one point of weakness - on the waterline of it's starboard hull.  Your only hope for survival is to board the Black Pearl, armed with dynamite, descend into it's hold, and blow a hole in the ship's side.
