You swim faster than normal.

Prerequisite: Swim 6 ranks.

Benefit: You swim at one-half of your land speed as a move-equivalent action, or at your full move speed as a full-round action. If you already have a native swim speed as a species trait, mutation, or other ability, that speed increases by 50%.

Normal: You swim at one-quarter of your land speed as a move action, or at one-half your land speed as a full-round action.
