Diamond Cove Marina
Montauk, NY
Diamond Cove Marina on Montauk harbor offers gasoline & diesel, 30/50 amp electric, 30 & 40 ton travel lift, ice, bait, batteries and marine supplies. It features the family-owned Hideaway cafe & bar serving Mexican, BBQ and seafood with harbor views.
Marinas typically need to separate slip holder parking from day-visitor parking, trailer areas, launch ramps, and secure dock access points. Modern facilities use barrier gate systems to enforce these zones automatically — allowing permitted vehicles through via transponder or keycard while logging all access events.
