Visit Diamond Marine’s Gigantic Indoor Showroom

At Diamond Marine, we offer a wide selection of Quality Pre-Owned Vessels. As one of the North East’s largest boat dealers, Diamond Marine welcomes quality trades, and for this very reason, we can offer our customers a very exciting range of Pre-Owned Vessels.

At Diamond, we thoroughly inspect all Pre-Owned boats, putting them through a rigorous 100-point inspection. Needed fluids are changed, and any items requiring repair or adjustment are updated to spec. We also thoroughly clean and detail the entire boat from bow to stern.

Come visit our gigantic 40,000 Sq. Ft. Indoor Showroom and see what we mean when we say Diamond Marine stands behind every boat we sell.

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

Call Diamond Marine

at 203-466-5384 to arrange an appointment, or simply stop buy our East Haven, Connecticut location.
