At Great Peconic Bay Marina (GPBM) we offer a friendly, helpful and fun resort like atmosphere where you can spend quality time with friends and family while enjoying the pleasures of being a boater on the beautiful North Fork of Long Island. GPBM is located in the quaint 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 trouble-free delight. 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!
A long walk to the beach and if we were docked near the beach it would’ve been too far to walk to showers. No, dock hands. No toilet paper in the ladies room. We will not go back.
