Sea Ray 340 Sundancer Review, an Iconic Cabin Cruiser

Sea Ray’s Sundancer series needs little introduction and has led the company line-up for decades. The Sea Ray 340 Sundancer, launched in 1999 and manufactured through 2007, positively dominated the express cruiser market at the time and has remained a firm favorite with owners ever since.

When first launched, the 340’s sleek styling, forward-leaning radar arch, and combination of luxury, speed, and craftmanship set it apart from its competitors. Not only was it fast—equipped with twin MerCruiser 8.1L 375hp V-drive inboards that saw it reach 28 knots or more—but it looked fast, too. Very quickly people realized that this wasn’t your average cabin cruiser, and its design has meant it's remained current ever since.

The 340 was conceived with boating families in mind, from the twin cabin layout, impressive interior space for a 34-foot boat, and the spacious galley. It is luxurious, with dark cherrywood and plush soft furnishings, and also sturdy, safe, and sporty. Whether it’s a weekend away or an extended cruise, it sleeps and dines up to 6 comfortably, and the 225-gallon fuel capacity allows for longer-range exploration than most of its competitors. Find a model with the sought-after Sportsman’s Package, and it turns this already versatile and capable cruiser into a mean fishing machine, too. Is there anything the 340 can’t do?
