As the name implies, this minor rite takes the form of a short song used to keep a boat from running aground or getting tossed in rapids while on its journey. No one aboard gets seasick and the boat makes good time regardless of the weather.
If the Garou performs this rite each time before he gets into a boat for a full month, he and everyone in the boat gains two dice to their Boating Skill, even if inexperienced. However, failure to perform the Boat Song before boarding a boat revokes the blessing, and the Garou must begin anew.
