Bennington 188SL Pontoon Boats for Sale - photo 2

Bennington 188SL Pontoon Boats

The 188SL is built on the same aluminum pontoon platform as the rest of the S Line with the same fit and finish standards, just at a smaller scale. Standard features include bimini top, swim ladder, stereo, and Bennington’s standard furniture appointments. The open bow layout seats up to 9 passengers, which is a full boat for a 19-foot platform.

The 188 in the model name refers to the 18-foot class deck length, which is shorter than the 20SL and 20SSR but still a full-sized pontoon in terms of usable space. For NH lakes like Lake Winnisquam and Ossipee Lake, where the water is calm, and the boat lives on a trailer rather than a slip, the 188SL is one of the easiest pontoons to own and manage.

Why Bennington 188SL Boats

The 188SL is available with Bennington’s SPS performance package, which adds a third center tube and WaveTamer technology. On a 19-foot boat, the SPS is typically paired with engines in the 60 to 90 horsepower range. The handling improvement is real, but the case for SPS is slightly less urgent on the 188SL than on the 20-foot models simply because a 19-foot boat at the right engine rating already handles well on most NH lakes.

Where the SPS makes the most sense on an 188SL is for buyers who want to tow tubes or occasionally ski, or for buyers who run on larger water where chop is more common. For calm-water cruising and fishing on protected lakes, the standard two-tube 188SL is a capable and cost-effective boat.

Great group of people, made the process of trading the old boat and buying a new one easy. The front office area, their service team, and our sales guy (Jeremy) did a great job answering all our questions and getting things done. Looking forward to next year's boating season.

I bought a boat in August from Jeremy Onos at Winnisquam. He was so fantastic to work with. Friendly, professional, very knowledgeable, responsive, high integrity kind of guy. I will definitely buy my next boat from him. And the rest of the team and service group at Winnisquam Marine were also a total pleasure to interact with. Great quality boats and great marina. Highly recommend.

We had a great experience working with Jeremy at Winnisquam Marine buying our first family boat. From the beginning, he was extremely helpful, knowledgeable, and accommodating. Being first-time boat buyers, we definitely had a lot of questions (some probably pretty dumb lol), but Jeremy never made us feel that way. He took the time to explain everything and answer anything we asked. We’re about an hour and a half away, and Jeremy even stayed late on a Friday so we could come up and see the boat. Once we got there, he let us take as much time as we wanted looking everything over and we never once felt rushed or pressured into making a decision. Throughout the entire process Jeremy was honest, helpful, patient, and did whatever he could to make everything easy for us. We eventually decided to purchase the boat and honestly couldn’t have asked for a better experience buying our first one. When the time comes to upgrade or make a change in the future, I have no doubt we’ll be going back to Jeremy. Highly recommend him and Winnisquam Marine!
