Our Thoughts

The 2024 Sea Ray SLX 310 represents the pinnacle of modern sport boat design—a 31-foot 6-inch express cruiser engineered for both entertaining and performance. Located in Colchester, Vermont, this single-owner, freshwater-only Lake Champlain vessel arrives with exceptional credentials: under 50 hours of engine time, consistent dealer service since delivery, and a meticulous maintenance history that speaks to conscientious ownership.

Power and Propulsion

Twin 6.2-liter MerCruiser 350-horsepower engines paired with Bravo IIIx stern drives form the mechanical backbone of this SLX 310. The Axius joystick docking system transforms helm operation into an intuitive, single-hand affair—particularly valuable in tight marina situations or when maneuvering near docks. The Dynamic Running Surface hull technology, combined with Sea Ray's signature Quiet Ride™ design and Tuned Transom®, delivers a smooth, controlled ride across variable water conditions while maintaining the kind of responsive handling expected from a modern sport boat of this caliber.

Cockpit and Entertainment Layout

The SLX 310's design philosophy centers on social versatility. A spacious open bow accommodates a bow filler cushion and integrated bow table with teak overlay, while the main cockpit features a convertible aft-facing lounger that transforms into a sunpad—ideal for anchored relaxation or dockside entertaining. A cockpit table with matching teak overlay and integrated storage anchors the social zone. The 120-volt electric grill and cockpit refrigerator support onboard food preparation, while the Sirius satellite radio and premier audio system upgrade ensure entertainment options throughout the day. Cup holders, grab handles, and thoughtful storage throughout the cockpit minimize clutter while maximizing usability.

Comfort and Shade

An opening fiberglass hardtop with extended sunshade provides weather protection and solar relief without sacrificing the open-air feel essential to sport boat enjoyment. The dune interior color palette complements the boat's modern aesthetic, while Infinity woven vinyl cockpit flooring resists wear and simplifies maintenance. Side entry door design eases boarding, particularly for guests or when docking solo.

Technology and Navigation

Dual 12-inch Simrad SelectResponse displays deliver chart plotting, sonar, and system monitoring capabilities in a clean, integrated helm layout. The shore power package with 120-volt converter and matching power cord supports extended dockside comfort, while the 12-volt to 120-volt inverter enables appliance use underway. A windlass anchor system with rope and chain handling—complete with galvanized anchor—provides reliable ground tackle for overnight anchorages or emergency situations.

Exterior Styling and Hardware

The SLX 310's full black hull, Horizon gel stripe, and black canvas package create an aggressive, contemporary profile that commands attention. Thru-bolted stainless steel cleats, navigation lights, transom handrails, and a matte-finish black windshield with tinted tempered glass and walk-thru opening establish a cohesive hardware package. The integral extended swim platform with under-mount ladder and grab handle facilitates water access, while RGBW LED lighting—including thru-hull accent lights—adds functional ambiance for evening entertaining. Docking lights, fender clips, and a stainless steel ski tow round out the practical exterior features.

2024 Sea Ray SLX 310: Premium Luxury Sport Boat with Twin MerCruiser Power
The 2024 Sea Ray SLX 310 represents the pinnacle of modern sport boat design, combining refined entertainment spaces, responsive joystick-controlled handling, and the kind of thoughtful engineering that makes time on the water feel effortless. This 31.5-foot freshwater vessel, powered by twin 6.2L MerCruiser 350HP engines with Bravo IIIx stern drives, is built for owners who demand both performance and comfort without compromise. Located in Colchester, Vermont, this single-owner example has accumulated fewer than 50 hours and has been maintained by Sea Ray dealers since new, making it a rare opportunity to acquire a virtually unused luxury day boat at a significant value compared to new pricing.
Overview and Design Philosophy
The Sea Ray SLX 310 occupies a distinctive position in the sport boat market—large enough to accommodate a full crew in genuine comfort, yet agile enough to deliver the responsive handling and acceleration that serious boaters expect. At 31.5 feet in length with a 10.17-foot beam and 3.17-foot draft, the SLX 310 balances shallow-water accessibility with the stability and volume needed for extended cruising and entertaining. The full black hull color paired with the Horizon gel stripe and black canvas package creates an aggressive, contemporary profile that stands apart from conventional white boats while maintaining the elegant proportions Sea Ray is known for. The SLX line emphasizes what Sea Ray calls the "Quiet Ride" hull technology, featuring a Tuned Transom design and high-performance vinylester resin construction. This engineering approach dampens spray and reduces vibration underway, creating a smoother, more refined ride quality than many competitors in the class. The result is a boat that feels substantial and controlled whether running at cruise or wide-open throttle, with the kind of predictable handling characteristics that build confidence in varied water conditions.
Helm and Electronics
The 310 SLX's helm station is equipped with dual 12-inch Simrad SelectResponse displays, providing comprehensive navigation, engine monitoring, and system management through an intuitive touchscreen interface. The Simrad ecosystem integrates sonar, autopilot, and waypoint navigation into a unified platform, allowing the operator to make informed decisions about routing, depth, and weather with confidence. Joystick docking via the Axius system transforms the experience of maneuvering in tight quarters—rather than coordinating independent throttle and steering inputs, the operator simply moves the joystick in the desired direction, and the boat responds with proportional thrust from both engines and coordinated rudder input. This system is particularly valuable in marinas, alongside docks, or when positioning for anchoring, where traditional helm control demands constant attention and fine adjustments. The matte finish black windshield features a walk-through design with tempered, tinted glass and stainless steel framing, providing excellent visibility while minimizing glare. A windshield wiper on the starboard side maintains clarity in rain or spray conditions. Below the helm, an interior storage compartment with LED lighting and carpeted flooring provides secure stowage for personal items, electronics, or documentation, while the flip-up bow cushion grants access to additional under-helm storage and the backside of the instrument panel for service or upgrades.
Cockpit and Entertaining Spaces
The 310 SLX's cockpit is designed as a social hub rather than merely a functional command center. An expansive open layout accommodates multiple passengers in comfort, with generous seating and lounging areas that invite entertaining. The aft-facing lounger converts to a full sunpad, allowing guests to recline and enjoy the water without interfering with helm operations or other activities. A fiberglass cockpit table with teak overlay provides a stable surface for drinks, snacks, or dining, while the wetbar—a standard feature on the SLX 310—includes an electric grill powered by a 120V inverter system, enabling onboard cooking without a full galley setup. The bow area extends the entertaining footprint with a spacious open layout and a bow filler cushion that transforms the forward seating into an additional lounging surface. Bow and stern tables with teak overlays create multiple gathering points throughout the boat, while stainless steel cup holders with rubber inserts and recessed holders in the bow side panels keep beverages secure in rough conditions. A cockpit cooler provides cold storage for provisions, and a lockable glove box on the port side stores valuables or documentation safely. Lighting plays a key role in the boat's ambiance and functionality. An RGBW LED lighting package with thru-hull lights allows customization of the mood—from bright white task lighting for safety and navigation to colored ambient lighting for entertaining after sunset. Navigation lights mounted on the hardtop and stainless steel docking lights ensure the boat is visible to other traffic and clearly marked when moored.
Swim Platform and Water Access
The integral extended swim platform with an under-mount swim ladder and integral grab handle makes water access safe and convenient. A submersible platform design keeps the swim platform level with the water surface when lowered, reducing the step height and making entry and exit effortless even for children or less mobile guests. SeaDek swim platform matting provides non-slip traction and a cushioned surface that remains comfortable underfoot in direct sunlight. The platform is wide enough to accommodate multiple swimmers or divers preparing to enter the water, and its integrated design minimizes the visual bulk that protrudes from conventional fixed platforms.
Deck Hardware and Safety
The SLX 310 is equipped with substantial stainless steel hardware throughout, including eight thru-bolted 8-inch cleats suitable for securing to fixed docks or mooring fields. Bow and stern eyes provide tie-down points for anchoring systems or towing, while two transom handrails offer secure grip points for passengers moving around the boat in rough conditions. A stainless steel ski tow attachment is integrated into the transom, supporting watersports activities for owners interested in skiing, wakeboarding, or tubing. The anchor system includes a windlass with rope and chain capacity, a galvanized anchor, and a gas-assisted anchor hatch with dedicated storage, allowing the operator to deploy and retrieve the anchor from the helm without manual hauling. Fender clips and dedicated fender storage with a fiberglass hatch keep docking gear organized and protected. The rub rail features a PVC extrusion with stainless steel insert, absorbing impact energy during docking while protecting the hull from scrapes and damage.
Mechanical Systems and Power
Twin 6.2-liter MerCruiser 350HP engines with Bravo IIIx stern drives provide the 310 SLX with responsive acceleration and sustained cruising capability. The Bravo IIIx drive incorporates advanced hydraulic systems and trim-and-tilt functionality, allowing the operator to adjust the drive angle for optimal performance across a range of speeds and sea conditions. Dynamic Running Surface technology, integrated into the hull design, automatically adjusts the running attitude to maintain optimal trim throughout the speed range, reducing fuel consumption and improving ride quality. A 130-gallon fuel capacity supports extended cruising, while a 24-gallon freshwater capacity supplies the galley, head, and shower systems. The engine compartment features an electrically actuated hatch with a gas-assisted lift, providing easy access for routine service, fluid checks, and maintenance without requiring manual brute force. An integral engine compartment vent system prevents heat buildup and ensures adequate air supply for combustion and cooling. The electrical system includes a shore power package with converter and 120V/60Hz cord, allowing the boat to draw power from dockside pedestals while moored. A 12V to 120V inverter supplies AC power to the electric grill and other 120V accessories when operating away from shore power. This hybrid electrical approach maximizes flexibility for different boating scenarios—full AC power when docked, and selective AC capability for entertainment systems and appliances when cruising.
Interior Comfort and Audio
The SLX 310's interior emphasizes quality materials and intuitive functionality. A premium Dune interior color scheme creates a warm, inviting atmosphere that complements the boat's contemporary styling. The cockpit flooring features Infinity woven vinyl, which resists staining, UV degradation, and mildew growth while providing a comfortable surface underfoot. A side entry door with a fender clip system facilitates safe boarding, particularly for guests unfamiliar with boat entry procedures. Audio entertainment is handled by a premier audio system upgrade paired with Sirius satellite radio, allowing passengers to enjoy their favorite music, news, and entertainment without relying on cellular coverage or local radio stations. The system is integrated throughout the boat's cockpit and cabin spaces, creating a cohesive entertainment experience whether the boat is underway or moored.
