For over a decade, Diamond Marine has been breaking new ground in bringing to the boating community a wide selection of very competitively priced new and pre-owned boats, backed by a commitment to outstanding customer service and support. We also specialize in International sales and shipment of vessels, and our in-house service department offers expert service, repair and maintenance for all leading motor/vessel manufacturers.

We invite you to visit our gigantic 40,000 square-foot indoor showroom —the largest in the North East!
As the largest Worldwide dealer for Steiger Craft, we can offer extremely competitive pricing and expert service to our customers. Additionally, our location’s close proximity to Steiger’s Bellport, Long Island, factory has created a unique relationship in our ability to provide quick delivery of boats from our in-house inventory as well as offering the option to custom order vessels in a wide range of hull colors, and with a variety of customer personalized features direct from the factory.
