Diamond Marine At Diamond Marine we are your one stop shop for all things nautical. We have the largest Indoor show

At Diamond Marine, we've consistently out performed our competitors for a number of very good reasons, and our customers have benefited as well. First, we have developed very good relationships with our new boat manufacturers. We buy all of our vessels outright, verses on consignment, which gives us a tremendous price advantage that we can pass on to our customers. Diamond Marine has stood the test of time, having been in business for over 35 years. For our customers, this means that when you buy from us you can be assured that we’ll be here to stand behind our products should you need us. In addition to our new boat lines we also accept quality trades and source high-quality, exceptional condition pre-owned boats. This allows us to offer our customers an alternative to a new vessel purchase. I also have a belief in presenting our products in the best environment possible, so at Diamond Marine, we’ve built the largest indoor showroom in the Northeast, and have filled it with an extremely large inventory. So that in one location, our customers can do extensive comparison-shopping, across a number of brands. Lastly, we do a considerable amount of business outside of the U.S. Here, we offer our international customers the benefits of a very good exchange rate, and our considerable experience in vessel export, makes the process not only affordable buy worry free as well. If you’re considering getting into boating for the first time, or are an experienced boater looking to upgrade, or downsize for that matter, I encourage you to call me directly at (203) 466-5384 and let me show you exactly the difference Diamond Marine can make.

The WaveBlaster is back.

Thirty years after the original built a cult following, Yamaha just brought the name back — and this isn't a reissue. It's an all-new WaveRunner built to lean into every corner like a dirt bike on water.

No sponsons. No excess. Just a 425-lb hull, a 1049cc TR-1® HO engine, and a ride built for people who treat the dock like a starting line.

Neon yellow. Splatter graphics. Hand-lettered script. The look that started it all, on a hull that's never existed before.

Some riders see open water. Others see a racecourse.

The 2027 Yamaha GP Series is built for those who live for the hard turn, the clean line, and the feeling of pulling away when the throttle is pinned.

Sharp. Fast. Focused. GP is performance with a Yamaha badge.
