7.25 Swim (Str)
The Swim skill represents your ability to swim. A creature that is in water without a swim speed takes a -2 penalty to its accuracy and Armor and Reflex defenses, even if it makes a successful Swim check. For details, see Fighting In Water.
Creatures that are native to water, such as fish and monsters with a swim speed but no land speed, gain a +10 bonus to Swim checks.
7.25.1 Common Swim Tasks
Move: You can make a Swim check as a movement while you are in water or a similar liquid. This requires two free hands, or one free hand if you take a -5 penalty. The difficulty value is based on the turbulence of the liquid. Success means that you move through the water, up to a maximum distance equal to a quarter of the base speed for your size (see Size Categories). Critical success means the maximum distance you can move increases to half of your base speed.
7.25.2 Swim Speed
Some creatures have a listed swim speed. A creature with a passive swim speed must still make a Swim check to move in liquid. However, the distance it can move if it succeeds on the Swim check is equal to its listed swim speed, regardless of its size or whether it gets a critical success.
