Overview

The Sea Ray 350 SLX stands out as one of the largest bow riders in its class, designed with a strong emphasis on capacity and entertainment. It can accommodate up to 18 people, with seating for 11 facing forward while underway, making it ideal for large groups. The boat combines luxury, spaciousness, and thoughtful design elements to enhance the onboard experience.

Exterior Design and Seating

The 350 SLX features extensive wrap-around seating in the cockpit, including a unique aft rumble seat with adjustable positions and integrated headrests for passenger comfort. On the starboard side, a double-wide love seat showcases high-quality upholstery with multiple tones, bead welting, and bracelet stitching, a design theme consistent throughout the boat. The port side offers double-wide observer seats with individual flip-up bolsters that rotate to face the action. Forward seating at the bow is ergonomically designed, starting at four feet wide and tapering to 16 inches, with flip-down armrests, integrated bulwark armrests, and grab handles. Optional features include a side-mount pedestal table in the bow for cocktail or alfresco dining, a hydraulically actuated table in the cockpit, and filler cushions that convert seating areas into sun pads.

Entertainment and Amenities

The 350 SLX is well-equipped for entertaining, with a solid surface counter for food preparation, a stainless steel sink, and ample storage that can be outfitted with an electric grill. Cooling needs are met with a refrigerator, as well as coolers located under seats in both the cockpit and bow areas. The aft rumble seat, when closed, provides a secure area for strapping down water toys. Audio enjoyment is enhanced by aft-facing speakers and stainless steel drink holders. Water access is facilitated by an optional hydraulically actuated swim step that automatically lowers the outdrives when deployed. Shade options include a manta shade at the bow, a standard hard top over the cockpit, and a retractable sunshade extending to the aft rumble seat. The boat also features courtesy lighting that adds both safety and elegance during nighttime use.

Interior Living Spaces and Comfort

For extended stays, the cockpit can be enclosed with Isinglass and equipped with heating and air conditioning. The helm console is spacious enough to convert into a berth, offering 54 inches of headroom that tapers forward. Natural light enters through opening port lights and a skylight above. Opposite the helm, a roomy head is included, providing convenience for overnight guests.

Power and Performance

The 350 SLX is powered by twin 300 horsepower 350 Mag engines as standard, with an option to upgrade to twin 380 horsepower 8.2-liter Mag engines. Both setups can be controlled via an optional Axios joystick. Daily engine checks are simplified by an electric lift hatch at the stern, and the engine compartment incorporates QuietRide technology with noise-absorbing materials and full beam bulkheads to minimize sound intrusion into the passenger areas. The helm is well-appointed with a double-wide seat featuring flip-up bolsters, a moving map display, push-button engine start and stop controls, spotlight remote, dynamic running surface controls, digital throttle and shift, and the Axios joystick.

Performance Data

The boat measures 34 feet 6 inches in length overall, with a beam of 10 feet 6 inches and a draft of 37 inches. With an estimated test weight of 13,660 pounds, including fuel and two passengers, the 350 SLX achieved a top speed of 47.2 miles per hour at a fuel consumption of 50.2 gallons per hour. At best cruise speed of 27.8 miles per hour, fuel burn dropped to 19.5 gallons per hour, allowing for nearly 7.5 hours of cruising and a range of 205 miles with a 10% fuel reserve. The boat planes quickly, reaching planing speed in 2.9 seconds, 20 miles per hour in 4.4 seconds, and 30 miles per hour in 6.2 seconds. The ride remains smooth and comfortable, with minimal bow rise during acceleration, aided by the Dynamic Running Surface system that maintains a nearly level cruise attitude.

Conclusion

The Sea Ray 350 SLX successfully combines luxury, capacity, and performance in a large bow rider format. Its thoughtful design prioritizes passenger comfort and entertainment, while its powerful and quiet propulsion system ensures a smooth and enjoyable ride. The boat’s extensive seating, versatile entertaining options, and well-appointed helm make it a compelling choice for those seeking a spacious and refined day boat experience.
