New & Used Sea Ray Boats for Sale
Modern Yachts is Long Island’s exclusive Sea Ray dealer — the only authorized source for new Sea Ray boats across the East End, with full-service marina locations in Hampton Bays, Westhampton Beach, and Mattituck. We’ve been placing Sea Ray boats with Long Island and Hamptons owners since 1967, making us one of the longest-tenured Sea Ray dealers on the East Coast.
Sea Ray has been America’s most recognized boat brand for over six decades, and for good reason. Every model in the lineup — from the sporty SPX series to the flagship SLX 400 and iconic Sundancer cruisers — is engineered with premium materials, leading-edge technology, and a fit and finish that reflects the brand’s position at the top of the American boating market. Sea Ray also backs their boats with the industry-leading SENTIN3L warranty program: a three-year bow-to-stern factory warranty, plus a 10-year limited structural hull and deck warranty on Sundancer and SLX 400 models.
Whether you’re looking for a fun, versatile day boat for summers on the Peconic, a luxury sport cruiser for entertaining on Long Island Sound, or an iconic Sundancer for weekend overnights along the Connecticut coast — our team knows every model in the Sea Ray lineup and will match you with the right boat for how you use the water.
Featured Sea Ray Models
21′ LOA | 8’6″ Beam | Outboard power | Up to 200hp
The entry point to the Sea Ray lineup and one of the most versatile day boats on the market. The SPX 210 Outboard combines sporty styling with a practical cockpit layout — plenty of seating, a bow lounge, and the performance to pull a tube or run across the bay at speed. Easy to trailer, easy to handle, and a natural fit for Long Island’s calmer bays and inlets. An ideal first Sea Ray. (More Info)
27’5″ LOA | 8’6″ Beam | Up to 400hp Mercury Verado
The SDX 270 is Sea Ray’s social deck boat — built for maximum fun with maximum capacity. A wide-open cockpit, optional watersports tower, and up to 400hp from Mercury Verado give it the space and power for a full crew to enjoy a day on the water. Whether you’re wakeboarding off Westhampton, anchoring in a Hamptons cove, or cruising Long Island Sound, the SDX 270 delivers non-stop entertainment. (More Info)
28’6″ LOA | 9’0″ Beam | Outboard power | Premium SLX appointments
Step into the SLX series and the experience changes noticeably. The SLX 280 brings premium leather seating, touchscreen helm interfaces, refined gel coat finishes, and a level of fit and finish that sets it apart from anything in its class. Fast, comfortable, and genuinely beautiful — this is the boat for the Long Island buyer who wants to arrive in style and spend the day in comfort. (More Info)
39’9″ LOA | 12’0″ Beam | 250-gal fuel | Triple Mercury Verado | Top speed 50+ mph
The Sundancer line has defined the sport cruiser category since 1975, and the 370 Outboard is its most sophisticated expression yet. Reviewers have called it the most well-thought-out boat they’ve ever seen — and it’s easy to understand why. Glass hardtop to the roofline, a spacious overnight cabin, full wet head, and triple Mercury Verado power that pushes it past 50 mph make this the choice for serious overnighting and weekend cruising. A waitlist boat — talk to our team about current availability. (More Info)
42’8″ LOA | 13’1″ Beam | 10-year structural hull warranty | SENTIN3L coverage
The pinnacle of the Sea Ray sport boat lineup. The SLX 400 earns its “Entertainer” reputation with a fold-down swim terrace, expansive cockpit social spaces, yacht-level interior appointments, and the SENTIN3L warranty program — three years bow-to-stern plus 10 years on the hull and deck structure. At 42 feet with a 13-foot beam, this is a boat that competes with full-size yachts in terms of presence and amenity, while remaining genuinely driveable. Talk to our Hampton Bays team about build options and inventory. (More Info)
Sea Ray Boats on Long Island & in the Hamptons
Sea Ray’s lineup spans every type of Long Island boating experience — and that breadth is exactly what makes them the right brand for our market.
Day boating and water sports: The SPX and SDX series are built for exactly the kind of summers Long Island delivers. The protected waters of Moriches Bay, the Peconic, and the calmer reaches of Long Island Sound are perfect territory for the SDX 270’s social cockpit and optional watersports tower. These are the boats you see anchored off Hamptons beaches on a Saturday afternoon.
Luxury cruising: The SLX series represents the current benchmark in American sport boat luxury. The SLX 280 and SLX 400 turn heads everywhere from Sag Harbor to Greenwich — the level of finishing, the touchscreen technology, and the sheer presence of these boats on the water is something you have to experience in person to fully appreciate.
Weekend overnighting: The Hamptons, Block Island, Montauk, Newport, and Martha’s Vineyard are all within realistic range for a Sundancer. The 370’s 250-gallon fuel capacity and 50+ mph top speed make weekend runs to Connecticut or Rhode Island genuinely easy — and the cabin, head, and berth make them comfortable enough that you’ll want to stay.
Local service when you need it: With Modern Yachts locations in Hampton Bays, Westhampton Beach, and Mattituck, certified Sea Ray service, warranty support, seasonal storage, and dockage are always within reach. You don’t have to drive past three other dealers to get your boat looked after.
