Match the boat to your waters
Pontoons and deck boats suit calm lakes. Deep-V hulls handle chop on larger lakes and coastal water. Center consoles are versatile for fishing. Ask Great Bay Marine - Flanders which models suit the waterways near Riverhead, New York.
Inspect the hull carefully

Request a sea trial
Test the boat on the water before buying. Run it at full throttle. Listen for unusual noises. Check that the throttle and steering respond smoothly. Reputable dealers like Great Bay Marine - Flanders will accommodate this request.

The word Great is in their name for a reason. They give Great service always professional and they know their stuff. Having great hours and convenient to get to by water and land. They always answer the phone. Great job. Ty. CHRIS is awesome.
These guys are not only good they are excellent! My salesman Gary, at the islip location, made sure all details were taken care of. There is no hard sell; they sell quality boats at a great price. In the Flanders location I had Rob and Jay help me with all the details to get ready to launch. They were super helpful, patient, caring and very nice. From sales to launch these guys are the BEST!!
The staff was very helpful. We rented a pontoon boat. The price was very reasonable and the bay that we were on was beautiful. I would recommend this to anybody in town.
This dealer has been nothing but AMAZING! I bought a “sister boat” and was having nothing but a nightmare with my dealer. They stepped in and have rectified every issue that I was having. They are professional, courteous and keep you updated. They follow through with attention to detail. I highly recommend them and am personally so grateful for their assistance. They have renewed my faith in boat dealers. Thank you!!!!
They are a good marina with friendly staff. But absolutely do not ever have them work on your boat. Twice I have had them do work the 1st time it took 7 months February till the end of August to get an engine swapped. Thankfully the owner of Great bay stepped in and got it resolved and I thank him for that. This July I asked them to install a outdrive and a lower shift cable. 3 months later it's still not right and as of today the boat won't shift into gear at all. Ruining my plans to go fishing tomorrow with my best friend. I have been patient and understanding but now it's just insane. Hopefully they will resolve this tomorrow and I can update the review. But I will absolutely never allow them to do work on my boat again. Another season ruined by bad mechanics. Update boat allegedly fixed took 6 months. But I haven't been able to take the boat out myself yet so don't know if it's actually fixed. Like I said nice Marina staff is nice. But absolutely positively do not ever have them do mechanical work. It takes them forever to get to it and takes multiple attempts to fix relatively simple problems.
