Once a busy whaling and shipbuilding centre, Greenport on Long Island's North Fork now lives mainly from tourism, marinas and a small inshore fishing fleet rather than commercial freight. The North Ferry links the village with Shelter Island, but the shallow approach of around 1.8 m keeps ocean-going cargo vessels away, and there is no container, bulk or breakbulk handling. Freight forwarders serving the metropolitan area route shipments through the Port of New York and New Jersey or New Haven. For practical purposes Greenport (US GP4) carries limited commercial freight relevance.
