The third annual Vandenberg Grand Prix will see participants use diver-propulsion vehicles to race around the 523-foot-long Gen. Hoyt S. Vandenberg, a former military ship sunk in 2009 approximately seven miles off Key West. On Friday, May 18th, racers will meet at the Rum Barrel, 528 Front St. The following morning a myriad of events will begin, including scooter demonstrations, race practice, manufacturer races and diver-propulsion vehicle certification for any racers who are not yet DPV certified. Finally, at 8:30 a.m. Sunday, May 20, the race will begin as divers zoom around the top of the Vandenberg’s superstructure, competing in multiple classes to achieve the fastest speeds while staying within safety parameters. An awards ceremony will follow.
