My wife and I purchased a 2027 Bennington from Zach Graham and the experience was exceptional. Zach is extremely knowledgeable and passionate about what he does. Zach answered every question I asked (I asked a lot) in a timely fashion and offered great insight every time. If you are considering a new or pre owned boat, I would highly recommend you speak with Zach Graham at Winnisquam Marine. He is a true professional.

Zach was great from start to finish. I am new to boating and he was gracious with all my questions. He took the time to really explain the boat and made sure we were all set when we picked it up.

From the first call to the final trailer strap — perfection. We bought a Bayliner E16, and from the moment we spoke with Alex, the whole experience went from “buying a boat” to “being treated like VIP clients at a private marina concierge service.” Alex’s expertise — off the charts Communication — instant, clear, and actually helpful Preparation — they handled everything White‑glove service — not the marketing kind, the real kind They didn’t just sell us a boat — they took care of every single detail like we were the only customers they had that day. Absolutely blown away by Winnisquam Marina.
