Welcome to Great Peconic Bay Marina
Great Peconic Bay Marina (GPBM) is located in the small town of South Jamesport. You can find us by water where the Great Peconic Bay and the Flanders Bay meet, known to many as Hawk's Creek. By land we are a short 7 miles East of the end of the Long Island Expressway. We have been family owned and operated since 1978. We have always taken pride in our service, marina facilities and our effort to make your boating a pleasure. We are a complete full service marina with an informal atmosphere.
Leave our entrance channel and you will be boating in the Great Peconic Bay!
