Easy, convenient for a visit to Northport.

Im sure there is a reason, but it eludes us. Since we are paying Seymours, We would have thought that the Seymour launch service would be willing/able to drop us at CYC dock from our mooring. They instead took us to their pier across the harbor from CYC and we needed to call CYC to come get us. CYC was willing to return us to our Seymour’s mooring after our dinner. Not customer centric thinking on Seymour’s part. Wasted a half hour in the humid heat from quality social time.
Marina Response:
We are sorry you were disappointed with our launch policies, please understand that our launches are USCG authorized to travel to and from our dock only and for this reason the policy is in place. Seymour's prides itself with knowing we hire the most highly qualified and trained Launch Operators on the harbor and for this reason won't bend the rules for one guest. We hope that this policy wont deter you from visiting picturesque Northport again.

The launch was efficient and the captains were pleasant. We had no trouble getting our guest mooring, thank you.

The launch drivers were terrific!

This was our second time at Seymours. The launch operation is first class. Northport is a busy little town with lots of visitors, but with two launches running almost continuously, we never had to wait long for a pick up.

Friendly Staff - Nice Location

Very friendly launch drivers!

by paulbmilana on Aug 16, 2020
Terrific service as usual. Guest moorings along east side hang right out into the channel with an easterly wind. Some boats passing 10 feet away during peak times :-/

Seymour’s service never disappoints! Enjoyed a great week on guest mooring Aug 1 - 7.

Seymour’s Boatyard is the best kept secret in the North Shore Of Long Island. Just ask the Piano Man😜

by themacster on Apr 23, 2020
Seymour's is the best! Great staff, great owners. They try to accommodate all. I highly recommend a visit or a seasonal rental. You won't be sorry.

by pjcrean on Apr 19, 2020
Cruising on the sound? This is a great stop...fuel, moorings, great staff, launch capts and a great town to visit and stretch your legs. Have relied on their services since the 1970s.

by mattysolow on Apr 17, 2020
Seymour’s Boat yard has provided me with a home away from home. From their properly maintained moorings, to their amazing launch Captains who monitor Channel 68. They will pick you up either from a seasonal or daily rental mooring to their dock, literally, steps away from the quaint Village of Northport. In town there are numerous restaurants, the best bakery and shops. Need fuel? They provide both diesel and gas. Have a pup? They are adjacent to one of the nicest dog friendly parks on Long Island. All that, plus one of the most beautiful Harbors on the North Shore of Long Island.

by breenerman on Apr 17, 2020
A Northport village landmark and long time family business. Great service. Grab a snapshot of Northport nautical history... and an ice cream or a snapple while fueling !

by boatlover31 on Apr 17, 2020
One of the best marinas out there. The staff is wonderful always working extremely hard. The tender service is fast and the launch operators are awesome. Dave is always around for any help that is needed.

by mfreedman on Apr 17, 2020
Seymour’s is a wonderful, family-run marina with a fuel dock and helpful, knowledgeable staff. It’s well positioned right near the Northport village dock, and right along the channel. They also have moorings and a fast and professional tender service.

by sound1966 on Apr 17, 2020
This will be my 5th season at Seymour's Boatyard. The Weber family runs a tight ship and is always there for advice or general help. Not to mention the above and beyond service on a general basis and especially in emergency situations. Dave is always out there! ALWAYS!! This is a family run facility ran by a great family and always helpful staff! Tight lines!!

by deedonovan on Apr 17, 2020
Stellar facility!! They are always their to help dock when fueling up, pleasant tender service.. Great people, great service and a clean environment
