Navigation is managed in part by a Loran-C unit. A loran unit is a small computer that receives timed radio signals from two or more low frequency stations and processes the information received to fix your position. A loran will fix your position within a thirty foot radius - much more accurate than a GPS unit and more reliable. Pilots and mariners use loran to determine their present course and position, speed, course to steer to a destination and the time to reach the destination. My loran will hold 100 waypoints - (fixed points in it's memory) that I can use to return to a certain position (like the entrance to Ponce Inlet) from anywhere at sea. I always remove my loran from the boat when not in use to protect it from the elements and salt air. |
