Winnisquam Marine

(45 reviews)

We purchased a used pontoon from Winnisquam Marine in August '26. Our first contact was Zach who…read morewas our salesperson. This being our first boat Zach was extremely informative explaining everything to us to make our buying decision seemless. He was a great resource and exercised patience with me as I tend to have a lot of questions. Shortly after we purchased it we had some issues with it starting and/or running. It seems that muskrats like to get into the engine area of a boat and chew on the wires because soy is one of the ingredients used in the wire casing... who knew? They were very responsive to help us and inspected the boat, diagnosed the issue and took the boat in for service. We were without our boat for 2 weekends in a row as parts were needed and had to be ordered. This is where it gets better. We had company coming up both weekends, when I posed our issue to them they made sure we had a rental both weekends so our entertaining didn't miss a beat. Shout out to McKenzie, she saved us from having to break the news to our guests that we wouldn't be going out on the lake. Rentals are in high demand at this time of year at Winnisquam Marine but McKenzie made sure we had one each weekend to entertain our guests. She was instrumental in helping us make sure our plans went off without a hitch. Thank you so much McKenzie! Then there is the staff, amazing group of people. I'm sorry if I didn't get all of your names but know you were all appreciated. A few mentions going out to Bob in service, Ray and Wes on the docks. Once again, they were so patient with me as I'm learning boating for the first time. You all made my experience with Winnisquam Marine outstanding. You have a customer for life.

I had an exceptional experience renting a pontoon boat for the afternoon. The boat was spectacular…read moreand beautiful and could seat 11 people! The dock hand Gavin gave an excellent overview of the features of the boat and provided excellent suggestions about how and where to most safely enjoy the excursion. Lake Winnisquam is large enough to be fun but also safe and not overwhelming. I highly recommend this company and Gavin.

Listen, I read through these reviews and I can't argue with them if they've had some of the…read morenegative experiences described. However, this is a dealership and there is a level of markup associated with their labor and parts...it's how they make money. Still, my experience was positive. I've been waiting for my boat since last summer. Raj, my salesman, has been great. The rest of the staff are positive and enjoyable folks through my interactions...I enjoy when they poke fun at Raj (sorry Raj haha). I noticed issues from the factory, they took care of the critical stuff and will take care of the rest when I bring the boat back in. It was easy, and they were attentive to my concerns and friendly. I plan to use them going forward if possible. Thanks! John Williams

They handle 800 boats every year with huge storage facilities, heated and unheated. Bought a new…read moreboat from them 13 years ago, a moderate sized SeaRay. Good service overall, with some issues 2 years of the 13. But, those were well handled. NOT this year, as I requested my boat mid-May with down payment as I usually do. They could not perform until after memorial day! I have heated storage and pay for full service of my boat every year. But being a long term well paying customer is now ignored. When my boat was not ready at Memorial day weekend, I then asked for a short delay for delivery (service could continue). They did nothing to ready my boat. I am now waiting another 1.5+ weeks, hopefully to get the boat. New ownership is not able to keep up with heated storage and full service. I would buy a boat somewhere else if you are expecting loyalty in service.

We had a problem with the engine idle on the MerCruiser engine in our boat…read more The first place I called wanted to charge me $150 per hour to come tow our boat to their marina to run diagnostics on the engine, and they wouldn't be able to do it for at least a week. Nope. Not gonna do it. Wouldn't be prudent. (Especially considering I just got here for my week of summer vacation, so if I wait for this place, my vacation will be done and I won't have used the boat at all.) Independent Marine sent someone to our place the same day. I think we called around 10 a.m. and James came to our place around 1:30 p.m. He quickly figured out what the problem was, showed me what was causing it and what part needed to be replaced. I'm sure he would have done it for me if I wasn't up to the task, but he was happy to teach me / show me what was wrong and let me do it myself.

I was in the market to replace my old boat with a different used boat. I got a good price at…read moreIndependent Marine for a boat I knew had been in storage. There was a problem with it, and Independent Marine addressed it quickly and at no charge. When it had a different problem, they took it back as a trade for the full price I paid applied to a different boat. I can't detail all the different ways they went above and beyond for me. I found the GM Janice to be honest and responsive. I will be storing my boat there over the winter. I highly recommend Independent Marine, and have suggested to my brother that he get a boat from them.

Our family have been loyal Lanes End customers for years. The simple truth is, they do great work…read moreand have wonderful customer service. 2 summers ago our 20ft cuddy cabin sank tied to our dock. Lanes End Marina was able to salvage the boat, clean it up and get her running again in no time. There is no task they can't handle.

Everyone kept telling me they couldn't even look at it for 2 weeks and that it would most likely be costly from what I was describing. I had just about thrown in the towel when I asked and got a tip from a girl that lives in the area and works at Jo Jo's (a great local store). She spoke highly of them because her dad gets all his service there. I trailered my boat and drove it over to Lane's End. I was greeted by the service manager (think his name was Tim?) who was so much more professional than people at other marina's I had been dealing with. He looked things over quick and you could just tell that he really knew what he was talking about. He gave me some prices up front and told me how long he thought it would take. I had my boat back in the water in just 2 days (and that was only because they had to get a part for it). And they were 100% fair on cost. It is rare anymore that a business will find you in a desperate situation and not try to take advantage of you............Can't say enough about how great they were. I will recommend this place to everyone.
