Rise and Shine

Constructing greatness

When it comes to marine engine alignment, there’s no room for error. An incorrect placement—by even just a tenth of an inch—causes major disturbances in the smoothness and straightness of a ride. Sea Ray uses cutting-edge robotic equipment that actually measures placements to within four-thousandths of an inch. That’s thinner than a sheet of paper. Sea Ray’s state-of-the-art, ISO certified process means that running the 21 SPX will always be stable, smooth, comfortable and a complete joy.

A force to be reckoned with

You won’t be able to see the watertight compounds that bind the hull and stringer to reduce flex on every Sea Ray sport boat. Nor will you be able to see the precision framing system used in production to ensure the mold’s proper alignment as the stringers and hull are bonded together. You can’t see the detailed construction process that ensures strength and durability, either. But each time you hit the water in the 21 SPX, you’ll feel just how solidly it’s built, and know that it’s built to last.

Stylish and sleek

With a sculpted hull and deck, the 21 SPX sports an edgy, head-turning design that offers more than beautiful lines. It also improves ride quality, performance and efficiency. Every component of the 21 SPX’s build, from the boat’s weight and balance to its sculpted strakes, is designed for optimal tracking, handling and shock absorption. The result is an undeniably elegant sport boat that performs as beautifully as it looks.

Cruise in comfort

The 21 SPX features a spacious cockpit with dedicated transom walk-thru and convertible port lounge invites socializing and conversation. The extra-wide bow on this brand-new sport boat provides for even greater capacity, and more fun with more friends. But the design is not only sleek and spacious—it’s smart. With abundant dedicated storage throughout the boat and the kind of ergonomics you’d expect from the most successful boat brand in the industry, function and style go hand in hand on the 21 SPX.

Get closer

Get even closer to the water with the large, full-beam swim platform that is seamlessly integrated into the 21 SPX’s hull. A clever design elevates the swim platform’s utility and beauty, allowing you to fully enjoy the on-water and in-water experience. And accessing the swim platform is easier than ever before with a transom walk-thru that connects the transom fun zone with the rest of the boat’s highly social cockpit.
