Diamond Marine

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 tes

t 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.

If your ideal day ends at the sandbar, the Yamaha CrossWave is where it starts.

Designed for how people actually use the water, the CrossWave turns a simple ride into a full-day setup. Pull up, drop anchor, and open the boat into a true social space—walkaround layout, deep storage for everything you brought (and everything your crew forgot), and the kind of stability that keeps the day going long after everyone else is packing up.

This isn’t just about getting there. It’s about owning the moment once you arrive.

From early throttle to late-afternoon float, the CrossWave delivers:
• Space to move, not squeeze
• Storage that keeps the deck clean and the vibe right
• Power that gets you there fast—and keeps it fun on the way back

The sandbar isn’t the destination. It’s the reason.

Why choose the Yamaha CrossWave for a sandbar day?
Because it’s built for the in-between—the hangouts, the resets, the unplanned hours that turn into the best part of the weekend.

The Yamaha CrossWave is built for riders who see the horizon as an invitation, not a limit.

With 82-gallons of integrated storage, the CrossWave carries everything an all day adventure demands. Gear, boards, coolers, dive bags, picnic kits, cameras. It all stows cleanly and stays secure, keeping the deck open and the experience uncluttered.

A 26-gallon fuel tank gives you real range and real confidence. Longer routes. Fewer fuel stops. More time exploring coastlines, coves, sandbars, and waterways that reward curiosity.

Yes, it can fish like no personal watercraft before it, but the CrossWave can do so much more. It's a true adventure touring WaveRunner built for exploring, cruising, swimming, towing, island hopping, and days that refuse to follow a single plan.
