Harbour

Full-service marina on Great Neck Creek at Copiague, on the north shore of Great South Bay, Long Island.

Guide

Approach and anchoring

Reached from the Great South Bay channel, then up the marked Great Neck Creek towards buoy 16. The creek is narrow and tidal, so a draught check against the tide is sensible for deeper-keeled boats. The bay channel runs from the Robert Moses Causeway eastward.

Practical

Around 77 berths on the creek. Winter haul-out and storage on the two-acre yard. Engine work covered by factory-trained mechanics for Mercruiser, Mercury, Volvo and Yamaha. Address: 519 S Great Neck Road, Copiague.

Ashore

Shops and services along Great Neck Road within walking distance of the yard. Tanner Park on the Copiague waterfront, with a beach on Great South Bay, lies about 1.5 km to the south-east.
