Those who know sailing know Annapolis-based Gary Jobson. The pre-eminent American ambassador for sailing, Jobson serves as ESPN's sailing analyst and NBC ‘s Summer Olympics sailing correspondent. His latest effort, The Magic & Mystery of Sable Island, an environmental documentary set in the Canadian Maritimes against one of the world’s most remote and beautiful landscapes, will premiere at 3:15 p.m. Sunday, April 3 at Annapolis Elementary School, 180 Green Street. The presentation is part of the 2016 Annapolis Film Festival and will include another short film by Jobson, Ted Turner's Greatest Race: 1979 Fastnet, which chronicles the ill-fated race in which more than a dozen sailors perished. Jobson will be available for questions after both films. Tickets are $12.50 for adults, $10 for students and seniors and are available at www.annapolisfilmfestival.com.
