This skill has to do with small wind or oar powered boats, of the kind used on rivers and lakes. Rowboats, kayaks, and canoes are examples of watercraft usable by this skill. It does not confer the ability to manage large ships of see (this is accomplished through the Ship Handling skill.) When the skill is chosen, the character must specify whether she is learning sailboats or oar-powered boats. Taking the skill to int(2) allows for the use of both types.
Critical Success: The rower or sailor is able to maneuver the boat at twice normal speed or make the boat function as if 50% more seaworthy.
Critical Fumble: The boat overturns, runs aground, or suffers some other misfortune appropriate to the situation.
