J. W. Shag Manchester. Isle Royale ' s Navigation Department may be her smallest, but our role is paramount in the oper- ation of the ship underway. The modern navigator makes use of the most advanced scientific devices in guiding his ship, but still he relies heavily on techniques as old as sailing itself, simple but effective techniques of fixing position with the stars and sun. The great drawback of such old methods, their uselessness in bad weather, has been largely overcome with the development of the LORAN svstem of radio navigation and piloting bv radar. Even satellites are being used as a kind of artificial star , and possibly in the future much of the routine navigating will be done by computers. But all of these systems, however sophisticated and clever, rely on a lot of electronic machines, subject to breakdown, and will probably never completely replace the traditional navigator with his sextant, chronometers, and almanac. LTJG A. T. Donnellv, Isle Royale ' s Navigator, is assisted by six quartermasters, one of the Navy ' s oldest rates. As Quartermaster-of-the-Watch, the QM acts as the OOD ' s enlisted assistant, keeping the ship ' s Log, observing and interpreting weather and submitting summaries to fleet weather forecasting facilities. He is responsible for rendering honors, operating navigational lights and tog signals, and maintaining and adjusting compasses and other bridge equipment. Off watch, the quartermaster assists the Navigator in obtaining fixes, and plotting courses. He keeps the Ship ' s large collection of charts and navigational publications corrected and up-to-date, makes routine com- putations of tides and currents, sunrise and sunset, time changes, and cares for the Ship ' s chronometers- precision clocks used in obtaining celestial fixes and keeping correct time aboard ship.
