+ | Any direction can serve as the plane of reference, as long as it is clearly defined for everyone using the system. All certified navigational tools in Known Space are sorcerously calibrated to share the same plane of reference. Celestial North, also called the Prime Direction, is the geospheric North of Arvandor; the artificial bubble horizons of sextants and octants correspond with the plane of the ecliptic that spreads out from the orbit of Arvandor, and permit the complex geometric computation to determine a ship's azimuth and bearing. | ||

+ | The sailmaster mate (also known as the quartermaster or signaller) is an enlisted member assigned to the Sail department in charge of facilitating and implementing watch-to-watch navigation and keeping the astronautical charts current under the direct supervision and control of the ship's sailmaster (navigator). He is also responsible for the care and maintenance of the ship's chronometer and other timepieces, of the navigational and signalling equipment and instruments, | ||

+ | The //Imirie// has six ratings assigned to the Sail department: three sailmaster mates and three lookouts, one of each for all three watches. |
