The Martha’s Vineyard detachment of the Coast Guard Auxiliary will offer a two-week GPS course for mariners beginning Nov. 28. The course will meet Wednesday evenings from 6 to 8 p.m. through Dec. 5 at the Martha’s Vineyard Regional High School. Pre-registration is required.

Students will participate in an interactive experience, with the goal of learning how to use a GPS for recreational boating. Those with their own GPS units are invited to bring them to the class. For additional information or to reserve a spot, call Auxiliary Instructor Chris Scott at 774-930-0921. A $40 fee covers the costs of the textbook and materials.
