Sea Ray’s L Series is the manufacturer’s most luxurious line and the L550 Fly is designed to show what the builder is capable of. The L550 Fly has top-of-the line materials from upholstery to countertops and cabinetry. She also has a practical side with the galley, salon, and helm on the same level, creating an inviting environment for entertaining.
Stairs on the port side of the cockpit lead up to the L550’s flying bridge deck. This represents one of the many gatghering areas of the L550 and it has several key elements. It begins with a J-shaped settee to starboard and a table with leafs that open onto stainless-steel supports. Sea Ray engineers used new technology to design the padding for the backrests and paid close attention to the angle of the backrests for all the flybridge lounges to make them more comfortable.
The backrest at the front of this lounge converts to make the seat adjacent to the helm forward facing. Ahead of the helm, a large lounge is a great place to stretch out and soak up some rays abaft the acrylic windshield. It has convertible pads that allow the lounge to become a chaise, complete with elevated leg supports.
To keep passengers entertained, the flybridge entertainment center comes standard with a grill (many competitors charge for the grill), and a stainless-steel drawer-style refrigerator. The countertop has space for serving the food and there’s a sink for quick cleanups.
Total Control. Forward to port, the flybridge helm has a single captain’s chair. The dash is fully equipped with a Caterpillar 7” (17.78 cm) color display for the motors, digital switching with a custom Sea Ray interface and tablet control and Raymarine touchscreen displays that control all on board functions. The steering wheel is on a tilt helm and the shifts and throttles are electronic to give the captain more precise control. Redundant controls for the bow and stern thrusters and windlass are also on the upper station.
The L550 Fly comes standard with a hardtop that has a power sunroof. Our test boat had an extendable awning at the aft end of the hardtop that brought the shade further back into the aft lounge seating. This can be swapped out for a full enclosure that includes air conditioning and heat.
From the flybridge we could see the L550 Fly’s clever and inviting bow seating area. There’s a forward-facing lounge plus V-shaped aft-facing cushions that can seat five comfortably around the table. In a clever design, the backrests for the aft-facing seats fold into what would normally be the storage areas beneath the hinged bottom cushions. This provides dedicated and protected storage for the backrests. The seating also has a remote for the stereo plus USB plug-ins. An optional bow sunshade that is erected on a stainless steel frame is available and stores under the forward facing seats.
Private Beach. Passageways to the stern are 1’5” (43.18 cm) wide at hip level and 10” (25.4 cm) wide on deck have 2’8” (81.28 cm) high stainless rails. With luxury being the operative word (as is the case with all the “L” series yachts) the L550 Fly’s swim platform is finished in teak and the aft 4’6” (1.37 m) extension lowers into the water to make it easier to load a tender/PWC or to create a beach area for swimming and hanging out while at anchor. Stairs are flush to the deck to port and reveal when the platform is lowered. When swimming, a reboarding ladder is concealed under a deck hatch to starboard and a grab handle is molded into the closed hatch to aid in reboarding.
A large trunk-style locker on the boat’s transom has racks for fenders and docklines making it easy to keep the contents not only secured but organized. The opening is ringed in stainless steel and the hatch opens on twin stainless-steel gas struts.
Three portside steps from the swim platform lead up to the L550 Fly’s cockpit. The passageway closes with a gate that has a stainless-steel rail and acrylic insert. The cockpit has an L-shaped lounge wrapping around a triangular table so passengers can enjoy the outdoors on a nice day. The table collapses for easier entry and egress to the seating. Forward in the base of the flybridge stairs, there’s a stainless steel refrigerator drawer and a storage locker above. Gates to both sides open to allow boarding from a fixed pier when the swim platform boarding becomes inappropriate.
Main Deck Interior
A three-section sliding Opacmare stainless-steel framed door opens completely to create open passage to L550 Fly’s interior deck. Following a current popular design trend, Sea Ray put the galley, salon, and helm on the same level, which gives the area a large, spacious feel. This is further enhanced by the 6’5” (1.96 m) of overhead clearance.
Aft to port, the galley is located squarely between the forward salon and aft cockpit, ensuring that the chef remains at the social hub of the yacht. It has a big Silestone Natural Quartz Surface countertop with a recessed sink that includes a single-lever faucet and a wood cutting board cover. There is a two-burner induction stove and under-counter refrigerator and freezer drawers available in any configuration of the two desired. The microwave oven is hidden in an overhead cabinet that is finished in the same walnut that we will see repeated throughout the boat. Below are two clever storage solutions, one being next to the refrigerated drawers for holding narrow items like cleaning supplies or bottles. Under the sink is a sliding rack holding the trash containers that releases with the touch of a foot. The sole is finished in a wide-plank wood flooring. For morning Java, there is a Keurig coffeemaker. Additional storage is behind the counters and overhead behind acrylic laminated doors.
There are two swiveling seats at the forward side of the counter and Sea Ray cleverly left the area at the foot of the stools open allowing a clear sightline to the salon deck. This further adds to the open feeling of the entire main deck rather than allowing the bulkhead to create more of a division between the galley and salon. To starboard, we found the optional wine chiller and storage drawers for the silverware, glasses and plates.
SalonMoving forward, the L550 Fly’s salon has a Toscana upholstered sofa-sized lounge to port and a shorter one to starboard directly abaft the lower helm station. Two ultra suede ottomans have storage inside and reversible tops to convert to tray tables. A fixed pedestal table is an optional alternative, but stick with the ottomans if the convertible sofa is selected that converts the seating into a queen sized berth. The 50” (1.27 m) flatscreen TV rises out of the countertop directly abaft the starboard-side salon lounge and there’s a Bose SoundTouch entertainment system.
Complete Control. The L550 Fly’s lower helm has twin individual captain’s chairs that have armrests, reclining backrests, fold-down footrests and adjustable height. They also move fore and aft. The boat has electronic controls, bow and stern thrusters and a Caterpillar 7” (17.78 cm) color display for the engines. Twin Raymarine screens have digital switching with a custom Sea Ray interface and tablet control. A captain can touch an on board system icon on the screen and control a given function throughout the boat. For example, tapping the air conditioning button brings up the various cabins on the L550 Fly. He can touch the icon for the V-berth and adjust the temperature without ever leaving the helm. And Sea Ray engineered this so that every desired function can be accessed and activated with no more than two button presses.
Master Stateroom. The centrally positioned stairs lead to the L550 Fly’s cabin level. The master stateroom is aft and it has the queen berth angled from the aft starboard corner into the center of the stateroom. This saves space, but the cabin and a companion could feel more of the vessel’s movement than if the berth was on the centerline. To port, there’s an L-shaped settee and the hanging locker is to starboard behind a glass door. Just above is the 40” (1.02 m) flatscreen TV. There’s additional space in drawers in the base of the berth. Move the pillows and there’s a hidden storage compartment that also has an optional safe. The boat comes standard with a washer/dryer combo unit and separate units are an available option.
Guest Quarters. Working aft, the guest cabin to starboard has two individual berths that can slide together. These quarters have a hanging locker. In the bow, the VIP stateroom has a berth on the boat’s centerline with dual hanging lockers aft.
The Heads. The master head has private entry via a sliding pocket door to its head at the entry to the quarters. The countertop is the same Silestone Quartz as in the galley and there’s a vessel sink, a walk-in shower with an acrylic door and teak decking and the cabinets are lit on the sides. The day head is similarly equipped, albeit with a smaller shower stall. There is private entry to the day head from the bow VIP stateroom.
The Engines. The Sea Ray L550 Fly was powered by twin 850-hp CAT C12.9 inline-6 diesel inboards mated to transmissions with 1.964:1 gear ratios turning Veem 30” x 33.5” (76.2 cm x 85.09 cm) five-bladed propellers. Estimated weight of the test boat with two people, full fuel, and test equipment aboard was 69,595 lbs. (31,567 kg). We recorded a top speed at 34.9 (30.3 knots) mph at 2380 rpm. Best cruise came at 1700 rpm and 18.7 (16.3 knots) mph. The boat burned 39.7 gph (150.28 lph), which translated to .5 mpg, giving the L550 Fly a range of 246 statute miles with 10% of her 580-gallon (2,195 L) fuel capacity in reserve. In acceleration tests, she ran to 21 mph in 30 seconds.
The Engine Compartment. The L550 Fly’s engine compartment has an automatic fire-suppression system and Delta T 24-volt blowers. The engines are equipped with parallel start systems. Twin fuel filters protect each engine. The boat is equipped with an Onan 21.5 kW diesel generator with a sound shield and a dedicated fuel filter. The 240-volt water heater has a capacity of 20 gallons (76 L).
Options to Consider
The smallest entry in the L Series, the Sea Ray L550 Fly brings the luxury found in the larger models to a 56’3” (17.15 m) boat that an experienced captain can handle easily, especially with the standard bow and stern thrusters. The bow seating area is a big highlight as is the power swim platform. The single-level design for the galley and salon and the large flybridge make the boat well-suited for entertaining a crowd.
