Whirlpool

Whirlpools are a special type of object that are found infrequently in rivers and lakes. They were introduced at the beginning of World 10. 
==How to Use==
Whirlpools function as both a utility and a hazard. Using a whirlpool will transport you to another whirlpool somewhere else in the world, offering a fast mode of transportation across large distances.
However, using a whirlpool inflicts decay damage on your ship, and it is possible to break your ship and drown to death. Caution should be used with whirlpools, and it's advised to only use undamaged ships when entering whirlpools.
==Notes==
According to research done by LostJustice on the forums, whirlpools behave as follows:
-Whirlpools are not bidirectional, meaning that the 'destination' of one whirlpool does not necessarily connect to the original whirlpool.
-Whirlpools deal a base damage of 50% on boats, multiplied by the number of people in the boat. This means that entering a whirlpool with more than one person in your boat will result in certain death (or at least destroy your boat).
-Whirlpool destinations are temporary, and appear to change randomly on a biweekly basis.
