The Marina del Rey Flotillaof the U.S. Coast Guard Auxiliary will host a four-week GPS Navigation for Mariners course beginning Thursday, July 7 at the Del Rey Yacht Club, 13900 Palawan Way, Marina del Rey.

Each week’s Thursday class begins at 7 p.m. and ends at 9:30 p.m. Parking and refreshments are free.

This is a course for students who want to learn the theories and practical “how to” applications of the Global Positioning System (GPS).

The Flotilla 12-7 course covers the invention and evolution of GPS technology, how to navigate at sea with the system, including referencing real-time latitude/longitude read-outs, the meaning of waypoints and other data provided to users to make navigation more effective, and safer.

With this particular program, participants are encouraged to bring hand-held GPS units if they own them or purchase them to bring to class.

While there is no charge for instruction, a $50 public fee applies for course materials including a textbook. Customarily, most insurance companies will offer discounts upon receipt of a copy of the course completion certificate, according to the auxiliary.
