Everyone at Harbor Marina is incredibly friendly and helpful. A great place to be.

Friendly staff greeted us on arrival and helped with lines. It's a small marina with floating docks that were safe but feeling their age. Limited amenities (no pool) but nice, clean & modern bathrooms & showers.

Rick and team were great. Super accommodating with last minute requests, twice. Never said no, even after hours support. Very nice dock hands and restaurant is great too.

Not a good place for large boats. Plastic wobbly floating docks (!) with no real cleats, not suitable for a 50 foot boat. Tied up at 7pm, No marina staff on hand, no slip assignment and no off hours contact info at marina office door, etc. frustrating after a long day cruising. Staff friendly during day.

Marina Response:
Hi Eric, Thanks for your feedback regarding your recent stay at Harbor Marina. Sorry to hear you had trouble locating your slip, after hours, and ended up in a slip not well suited to your vessel. We are on site at the Marina from 9:00am to 5:00pm, seven days a week in season, and provide full dockage support and related services during these hours. We monitor VHF channel nine during our regular operating hours on two powerful base stations and multiple handheld units. Should a transient dockage customer or other marina guest require after hours support, we ask that they contact us 24 hours prior to their arrival to ensure that we can properly support their boating and dockage requirements. We have updated our dockwa and marinas.com profiles to make sure this arrival policy is crystal clear. Thanks for bringing this to our attention. In appreciation for your taking the time to provide us with some feedback on your last stay, we would like to offer you a 10% discount on your next stay and provide you with the five star service that we are known for in the Hamptons Boating Community. Thank you, Rick Drew Dockmaster
