About Our New Boats

Visit Diamond Marine Gigantic Indoor Showroom

Our huge Indoor Showroom (the largest in the Northeast) lets you comparison shop a wide range of new and used vessels... easily comparing models, features, and boat designs.

Diamond Marine carries proven and leading brands, covering the entire range of boating styles- from luxury cruisers and sport fishing vessels to high-performance runabouts.

Outside, you'll find even more boats to choose from. At any given time, we have over 50 boats in stock, and we're also more than happy to special order any vessel to meet our customers' unique style and performance needs.

And, best of all, we welcome high-quality Trad, so there's no better time than NOW to upgrade, or to get into a newer more fuel-efficient vessel.

We invite you to visit our gigantic 40,000 square-foot indoor showroom - the largest in the North East!
