Our Thoughts

The 2018 Sea Ray L550 represents the pinnacle of Sea Ray's L-Class motor yacht series—a 55-foot cruising platform engineered for owners who demand both capability and refinement without the complexity of larger vessels. Located in Baltimore, Maryland, this particular example has been meticulously maintained and upgraded throughout its ownership, making it an exceptionally well-equipped choice for extended coastal cruising and entertaining.

Propulsion and Handling

Twin Caterpillar C12.9L diesel inboards with direct drives deliver the power and efficiency expected from this class, supported by a comprehensive suite of modern maneuvering systems. Bow and stern thrusters integrated into a dual-station joystick control system—with independent helm and cockpit stations—make docking and close-quarters handling genuinely effortless, even for a 55-footer. The engines have logged only 570 hours and received complete service in August 2025, including oil, filters, fluids, belts, and impellers. An oil changer system for both engines and transmission further simplifies routine maintenance. The extended-range fuel capacity of 800 gallons supports serious cruising distances, while the 150-gallon freshwater system accommodates extended time away from the dock.

Electronics and Navigation

The electronics suite reflects a comprehensive Raymarine integration built around dual GS165 chart plotters, a p70RS autopilot display, i70 depth display, integrated bilge and cockpit cameras, Sirius weather module, and a 4kW open array radar system. A Caterpillar 7-inch color display provides engine instrumentation and alarm data directly to the chartplotter, creating a unified helm station that prioritizes both safety and situational awareness. VHF radio with remote speaker and 8-foot fiberglass antenna complete the communication package.

Stabilization and Comfort

A SeaKeeper 9 gyroscopic stabilizer dramatically reduces roll motion—a game-changer for comfort during extended offshore passages or simply anchored in beam seas. The 29kW Onan diesel generator provides abundant electrical capacity for the air conditioning, heating, and all hotel loads, while a zone-controlled reverse-cycle system with 68,000 BTU capacity maintains comfort across three staterooms regardless of season or location.

Layout and Accommodations

The L550's interior arranges three staterooms and two heads across a full-beam master aft, forward guest stateroom, and mid-stateroom with convertible twin bunks that form a larger sleeping surface. The master features a queen bed, full head with rain shower, cedar-lined closet, L-shaped lounge with storage, and entertainment center with 40-inch LED flatscreen and Blu-ray player.

2018 Sea Ray L550 Motor Yacht for Sale in Baltimore, Maryland
Overview
The 2018 Sea Ray L550 represents the final and most refined iteration of Sea Ray's distinguished L-Class motor yacht series, a platform engineered for owners who value both cruising range and ease of operation. At 55 feet in length with a 15.6-foot beam, the L550 strikes a deliberate balance—substantial enough to accommodate extended offshore passages and overnight guests in genuine comfort, yet responsive enough for a couple to manage without crew. Positioned at $975,000 and located in Baltimore, Maryland, this vessel combines proven Caterpillar diesel propulsion with integrated joystick docking control, comprehensive Raymarine electronics, and a three-stateroom, two-head interior layout designed around modern cruising priorities rather than traditional superyacht conventions. The boat's pedigree reflects Sea Ray's three decades of motor yacht refinement. The L-Class departed from the company's center console and express cruiser heritage to establish a purpose-built platform for blue-water cruising families and couples seeking a blend of seaworthiness, comfort, and operational simplicity. This 2018 example has received substantial mechanical and systems attention, with documented recent service across engines, transmission, generator, air conditioning, and stabilization systems, positioning it as a well-maintained asset ready for immediate deployment.
Hull, Deck, and Exterior Design
The L550's hull is constructed using Sea Ray's composite stringer system, finished in gel coat with integrated L-Class graphics and an illuminated Sea Ray emblem. The 4-foot draft reflects a design optimized for both offshore capability and inland waterway access, a practical consideration for owners operating along the Atlantic Seaboard and into Chesapeake Bay tributaries. Deck design prioritizes safety and entertaining functionality. The foredeck features elevated 316 stainless steel bulwarks with welded stanchions, intermediate rails, and integrated lifelines—a deliberate enhancement that both secures occupants and visually elevates the boat's profile. The elevated foredeck wraps around the bow in a recessed bench configuration with cushions and stowable backrests that fold beneath hinged seat bottoms, creating a flexible lounging zone. A removable bow table with storage legs completes the forward entertaining space. The arrangement supports five or more seated guests in opposing C-shaped lounges, and includes a Mediterranean -style sunshade with four poles and mesh construction, all stowing beneath the aft bench seat for days when full sun exposure is preferred. Teak flooring spans the cockpit, foredeck seating area, and swim platform, establishing a classic aesthetic while providing functional slip resistance. The windlass features an anchor chute in stainless steel, chain storage with gas-assisted hatches, and foot switches for intuitive anchor deployment. An ACR remote-controlled spotlight and dedicated anchor washdown spigot with hose complete the ground tackle and mooring infrastructure. The transom design departs from conventional crew quarters to maximize practical storage and tender capability. A wide hydraulic swim platform with self-folding, deploying steps accommodates depths from shallow anchorages to deep-water moorings. The platform carries a 1,000-pound lifting capacity and features tender chalks that slide out for easy tender removal. This configuration reflects an understanding that most American boat owners in this size class prioritize onboard storage and tender logistics over traditional crew accommodations. The 2023 Williams Minijet 280 tender—the product of the world's premier jet tender manufacturer—provides a premium, compact runabout suitable for exploring shallow-draft destinations and attending waterfront events. Wide side access gates on both port and starboard facilitate seamless movement between the foredeck and transom, while fixed gunnel doors in the cockpit enable direct side access from a fixed pier without boarding via stern or bow—a convenience often absent on comparable motor yachts. The fuel fill plates, positioned beneath the folding footrest threshold, remain out of sight while remaining dock-accessible, eliminating trip hazards and maintaining clean deck lines.
Cockpit and Outdoor Living
The cockpit features a generous L-shaped sofa with storage, paired with a folding Corian table in Rain Cloud Matte finish—maintenance-free surfaces that resist staining and weather degradation. Overhead lighting combines switchable blue and white LED systems with dimmer control, establishing mood lighting for evening entertaining. An electric retractable awning covers the seating area, providing shade without the visual bulk of permanent canvas. Two 7.7-inch JL cockpit speakers, installed in August 2024, deliver networked audio integrated with the onboard Fusion stereo system. The cockpit entertainment center incorporates a grill with solid-surface countertop and stainless steel handrail, supporting casual meal preparation and social gathering. A 120-volt refrigerator, beverage holders, and a trash receptacle with cover complete the outdoor hospitality setup. The cockpit flooring is self-bailing fiberglass, directing water overboard without pooling.
Helm Station and Control Systems
The L550's helm reflects an owner-operator philosophy. Two helm seats with reclining backrests, armrests, stainless steel fold-down footrests, and heavy-duty pedestals with slides and swivels accommodate both the primary helmsman and a companion. The control station integrates electronic shift and throttle controls with a power-steering tilt wheel, eliminating the mechanical complexity of traditional cable systems while improving precision during maneuvering. The dash features a high-gloss instrument panel with backlit, illuminated weatherproof switches and electronic dimmer control. A custom Sea Ray interface displays engine and alarm data on a 7-inch Caterpillar color display, with parallel start capability for the dual inboards. The compass, air horn, windshield defroster, and wiper controls remain within immediate reach. A custom integral vent system delivers air conditioning to the dash area, preventing helm discomfort during summer operation. Critical to the L550's operational ease is the integrated joystick docking control system, which couples the dual bow and stern thrusters into a single, intuitive interface. One joystick is mounted at the helm; a second is positioned in the cockpit, enabling single-handed maneuvering from either station without reference to engine throttles or shift controls. This system transforms docking, anchoring, and tight-quarter navigation from a multi-step procedure into an intuitive push-and-pull operation—a feature that fundamentally changes the boating experience for owners who value simplicity and confidence in close quarters.
Raymarine Electronics Suite
The L550 is equipped with a comprehensive Raymarine navigation and monitoring ecosystem. Dual GS165 chart plotters provide redundant primary navigation, each displaying GPS position, charted waters, and integrated sonar data. The p70RS autopilot display enables hands-free steering along programmed routes, essential for long-distance cruising and fatigue reduction during extended passages. An i70 depth display presents real-time sonar data, water temperature, and speed-through-water information. A 4-kilowatt open array radar scanner provides weather detection and target identification to the horizon, critical for offshore operations and night navigation. The Sirius weather module delivers real-time weather routing and marine forecasts to the chartplotters. A VHF radio with remote speaker and 8-foot fiberglass antenna ensures reliable communication across all cruising grounds. Integrated bilge and cockpit cameras feed video to the Raymarine system, allowing the helmsman to monitor engine room conditions and transom activity from the helm display—a practical safety and operational tool. The entire electronics suite operates on a 12-volt/50-amp dedicated circuit with proper over-current protection and color-coded wiring with chafe protection.
Propulsion and Power Generation
Twin Caterpillar C12.9L diesel inboards, each producing 570 horsepower, drive the L550 through direct-drive propeller shafts. The engines feature freshwater cooling, dripless shaft logs with extra seal carrier kits, and a crossover fuel system with electric transfer capability. Three Racor fuel filters—two 75-1000MAX units for the engines and one 500MA for the generator—provide multi-stage fuel polishing, critical for long-term diesel reliability in extended cruising. A recent engine service completed in August 2025 documented oil and filter changes, primary and secondary fuel filter replacement, transmission fluid and filter service, belt inspection, and impeller replacement—maintenance that establishes a baseline of mechanical integrity. The Caterpillar engine display provides real-time monitoring of fuel consumption, engine temperature, and pressure parameters to the helm. Hydraulic trim tabs enable pitch control during acceleration and heavy-sea operation, improving ride quality and fuel efficiency. Spare propellers with holders are carried aboard, a practical provision for cruising in remote areas where propeller damage repair may not be immediately available. The vessel is powered by a 29-kilowatt Onan diesel generator
