Pirate's Treasure

As your crew is enjoying a grog in the dockside tavern, you hear gunshots and the clash of sabers in the harbor. A gruesome mutiny has broken out on one of the ships that has just returned from a pirating voyage. Because they couldn't agree on a fair distribution of the loot, the entire crew has turned on each other. The captain, for safety's sake, has locked himself in his cabin and now can't get out on his own. Loudly, he yells for help and in his desperation promises his golden compass to the one who can free him first. Its needle doesn't show the geographical direction, but is drawn to gold, so it always points in the direction of the next biggest treasure. This feature makes the compass an invaluable tool for freebooters like you. Can you manage to claim the compass in time before the other pirates get wind of this opportunity?
