Overview

The Sea Ray 310 SLX represents a new generation within the SLX line, emphasizing luxury, comfort, and a wealth of amenities. This model builds upon the brand's reputation by integrating numerous refined details that collectively elevate the boating experience. From its striking exterior finish to its thoughtfully designed features, the 310 SLX is positioned as a premium-level craft that appeals to discerning boaters seeking both style and substance.

Exterior Design and Deck Layout

The 310 SLX features molded contour lines complemented by a gel coat finish with a mirror-like sheen, enhancing its visual appeal even before launch. The bow area offers wraparound seating for six, including double-wide forward-facing seats with flip-down armrests and ample storage beneath all seating surfaces. A pedestal table can be installed on either side, and mounting points are provided for a bow shade system. The cockpit is designed for socializing, with wraparound seating extending from the stern up the port side. The port seat swivels with flip-up bolsters to integrate seamlessly into the seating arrangement. Additional storage is abundant, including a cooler that slides out from under a corner seat. The starboard side hosts an entertainment center equipped with an electric grill and a sink with hot and cold running water, supported by a six-gallon hot water heater and powered by a dedicated battery and inverter system. Access to the stern is facilitated by angled steps on the starboard side, preserving cockpit seating space. The stern area includes a versatile sun pad that converts into an aft-facing bench with five adjustable seat back positions, complete with drink holders, stereo remote, and accessory plug. The swim platform is treated with SeaDek for traction and includes a four-step reboarding ladder with leather-covered grab handles. The port console houses an enclosed head compartment featuring a vacuum flush toilet, stainless steel sink, wood shelf, opening port light, and non-skid decking.

Helm and Technological Features

At the helm, the 310 SLX is equipped with Sea Ray's Dynamic Dash, which incorporates two pieces of flush-mounted glass and dual digital screens with custom interfaces. The upper displays provide twin tachometers and outdrive trim indicators, while the center displays speed, fuel data, and can be switched to various inputs including mapping. Controls are accessible via touchscreen or joystick interface, integrating smart technology that adjusts lighting to preserve night vision and features an automatically rising anchor light. The helm seat is double-wide with separate flip-up bolsters and premium upholstery. Additional operational features include a concealed windlass at the bow with a stainless steel anchor roller and a concealed electrical panel adjacent to the helm console. The boat also incorporates an Axius joystick system, delivering precise and intuitive maneuvering, ideal for docking and close-quarters handling.

Power and Performance

The 310 SLX is powered by twin standard 250 horsepower MerCruiser 4.5L engines, accessed via an electrically actuated hatch that provides ample space for maintenance. During testing, the boat reached a top speed of 44.1 miles per hour at 4820 RPM, consuming 36.5 gallons per hour and yielding a range of 141 miles. The most economical cruise was recorded at 3500 RPM and 28.9 miles per hour, with a fuel burn of 17.8 gallons per hour and an extended range of 190 miles, even in choppy conditions while maintaining a 10% fuel reserve. The vessel planes quickly, achieving planing in 5.3 seconds, reaching 20 miles per hour in 7.8 seconds, and exceeding 30 miles per hour in 12.1 seconds. A dynamic running surface with flush-mounted automatic trim tabs along the chines enhances stability and reduces planning time. These tabs adjust automatically during throttle and steering inputs, maintaining plane at speeds as low as 14 miles per hour, which is particularly beneficial for slow cruising. Handling is solid and smooth, with the boat remaining dry and comfortable except when operating at full speed directly into choppy waves. Overall, the 310 SLX demonstrates open water capability and responsive performance.

Luxury and Comfort Details

Luxury is evident throughout the 310 SLX in subtle yet impactful ways. Leather-wrapped grab handles, reminiscent of larger yachts, and multi-tone fabric upholstery with redesigned seat cushions that are an inch thicker than previous models contribute to enhanced comfort. The seats feature multi-density foam, combining firm and soft layers for optimal support. The upgraded vinyl upholstery is soft to the touch while offering stain and weather resistance. Attention to detail is apparent in the use of double and diamond stitching patterns and custom embroidery accents. The windshield is uniquely curved both vertically and horizontally, with no trim molding along the bottom edge, enhancing aesthetics and visibility. The carbon-reinforced hardtop includes structural beams that eliminate the need for obstructive stainless steel supports, preserving sight lines. Additionally, the standard powered collapsible tower includes an opening sunroof and an extendable shore shade, further enhancing the onboard experience.

Conclusion

The Sea Ray 310 SLX exemplifies a comprehensive advancement in the SLX line, combining refined design, advanced technology, and thoughtful luxury features. Its performance characteristics, including quick planing, efficient cruising, and stable handling in varied conditions, underscore its capability as an open water vessel. The meticulous attention to comfort and detail throughout the interior and exterior spaces elevates the boating experience, making the 310 SLX a premium craft that commands pride of ownership. This model successfully raises the standard for luxury sport boats within its class.
