@SilverOwl: Hahaha, Why did you have to say that? I want to name the crew's ship the Silver Owl now...

@Sareebas: The sailing master controls the wheel and is usually the navigator, or well informed by the navigator with the ability to keep on course. 

@Sareebas & SilverOwl: Since we have a sailing master and navigator let us talk about how the duties will be divided. SilverOwl's character could draft maps, and work on routes. Sareebas's character could be well acquainted with land marks, or be able to use the stars as a directional map, so he/she would be able to sail across SilverOwl's routes.
