    Captain's Report

    Sea Ray 400 Fly docked
    With the standard swim platform, the Sea Ray Fly 400 has a LOA of 40' (12.2 m) and a beam of 13’6” (4.11 m).


    The new Fly 400 from Sea Ray represents a good-sized entertainment platform with an open floor plan that keeps the social areas well connected to one another. This is accomplished thanks to the single-level main deck that allows all the social areas to join together as one.Externally, she comes standard with white gel, but four color options ($6,250) are available… Onyx, Sea Ray Blue, Horizon and Patina."Elegance" is the first word that comes to our mind when viewing Sea Ray’s choice of rich materials, from stylish hardwoods and finishes to solid surface countertops.

    The Sea Ray Fly 400 is equally comfortable for a night on the town, a formal dinner, or a summer picnic with friends.

    Features Inspection


    The Fly 400 is boarded from the swim platform and stairs to port lead to the first of our entertainment gathering areas, the open cockpit. The Fly 400 can also be boarded from a fixed pier by stepping onto the caprail at the port side of the cockpit, and then again steps lead to the cockpit.

    L-shaped seating

    that wraps around a pedestal table ($1,783 for fiberglass, $6,250 for teak) to starboard opposes a stairway to the bridge ahead and to port. Two carry-on coolers are stored in exposed positions under the seats, allowing them to be slid out without having to remove cushions. The remaining seats all have the usual storage accommodations underneath. This is complimented by a large storage compartment accessible from the transom. The self-bailing cockpit deck comes standard with a non-skid fiberglass surface.Options include snap-in carpeting ($750), Seagrass woven flooring or teak decking ($5,833) that extends out to the swim platform. Indirect lighting allows for entertaining long after the sun drops below the horizon. A cockpit filler cushion ($1,250) creates a sun pad. Under the flybridge stairs, choose from the optional cockpit refrigerator ($1,667) or opt for the cockpit icemaker ($2,500). And the entire cockpit can be enclosed with isinglass ($4,167) for three season boating.Triple-wide opening glass doors with a flush threshold, allows the salon to blend seamlessly with the outdoor cockpit. We’d like to see a screen as standard for the door to keep the bugs out, but it is offered as an option ($1,917).

    Sea Ray 400 Fly seating
    L-shaped seating surrounds a triangular pedestal table. A pair of carry-on coolers store under the seat.
    Sea Ray 400 Fly platform
    Stairs remain flush to the platform until it is lowered, and then they automatically deploy.

    Swim Platform

    Just behind the cockpit, the swim platform is actually an entertainment venue in its own right. It extends 5’10” (1.78 m) from the transom. An optional outdoor galley ($8,167) can be located against the transom and allows for cooking in open air, rather than having to be concerned with maintaining ventilation of the salon. Underneath is a pair of storage drawers on stainless steel sliders. It requires either the extended platform ($6,333) or hydraulic option ($46,667) and an electric grill lies adjacent to the sink and a solid surface counter matches those in the yachts interior. To either side, two of the yacht’s 10” (25.4 cm) cleats are both mounted high, for securing to a fixed pier, and low, for cross-tying to a floating pier. For a really classy look, add underwater lighting ($2,667).

    Sea Ray 400 Fly outdoor galley
    A hatch covering the outdoor galley is held in the open position with a pair of gas struts. Notice the speakers completing the “tailgate party” accessories.


    Choose from an extended platform ($6,333) that can be covered in teak ($5,833) or a hydraulic platform ($46,667). The optional hydraulic platform has a 500 lb. (227 kg) capacity and includes innovative steps that self-deploy as the platform is lowered. It can be actuated with either a corded remote or wireless. With the 3’8” (1.12m) platform lowered, there’s still enough space in the 2’2” (.66 m) molded section of the platform to allow for staying dry. Food can then be handed down to the “private beach”. An optional audio system upgrade ($1,667) includes a transom remote.


    The comfort level extends fully forward to the bow where a standard multi-position sun pad offer sun worshipers a place to relax. Side rails, fabricated from 316 stainless steel, allow the area to be safely used, even when the Fly 400 is underway. An optional audio system ($1,333) includes speakers mounted to the side rails, bringing the entertainment outdoors and a simple Bluetooth music player allows for complete control of the tunes.

    The bow sun pad can be utilized in several positions.

    Too Much Sun?

    A clever shade system can be installed for all day comfort ($4,667).

    Flying Bridge

    Sea Ray 400 Fly layout
    The flying bridge creates another gathering area, in this case in open air.

    We make our way to the flying bridge from the port side of the cockpit deck. Once above, we are greeted with a gathering venue consisting of U-shaped seating to starboard and a refreshment center, consisting of a sink and refrigerator, to port. Swinging the helm seat around will add to the seating area. A fiberglass table with two extendable leafs is standard. A teak version ($8,333) is offered as an option. Overhead protection comes from either a full Bimini ($5,833) or a hardtop ($36,667) with opening canvas skylight.

    Sea Ray 400 Fly fly bridge
    The flying bridge adds another level of gathering aboard the Fly 400.

    The forward-most seat has a flip seatback that can allow for either adding to the U-shaped seating or creating a double wide forward facing seat to add more eyes watching the water ahead of the Fly 400. Just ahead of this seat is a large storage compartment.

    Sea Ray 400 Fly seat back
    To starboard, the seating has a flip seatback to allow conversion to forward facing seating. Just ahead is a large storage area. The stereo control is just below and drink holders are alongside the storage. Note, the stereo controls are no longer mounted here but have been relocated to the control station for easier access.

    Flybridge Helm

    The helm is mounted to port and the pod style console features an optional pair of 12” (30.5 cm) RayMarine Es hybrid touchscreens ($5,833 each). The standard bow thruster is linked with the V-drives for full functionality around the dock. For added functionality, a stern thruster can be added as an option. The thrusters can be independently operated with buttons within the joystick housing, making the Fly 400 even easier to maneuver.



    A combination of large windows and aft doors work together to blur the line between the inside and the outside. Aside from the massive amount of natural light, fresh air is equally welcome on all but the hottest days where climate control takes precedence. On those days, the upper deck is zone controlled by a 27,000 BTU reverse-cycle system for heat and air conditioning.Honeycomb blinds are standard for the massive side windows and a privacy curtain is fitted for the aft door, allowing both privacy and conversion to a sleeping area for those extra overnight guests. All flooring is hardwood. A standard TV includes a Blu-ray player, DVD storage and the yacht is pre-wired for coax. A upgraded sound system ($2,500) can be installed and will include a subwoofer amplifier and upgraded speakers. The salon has hardwood flooring.

    Sea Ray 400 Fly main deck layout
    The single-level main deck allows for a seamless transition between the social areas.

    An L-shaped lounge

    to starboard and an opposing second sofa to port will accommodate eight. And an option for a pull-out bed is available ($1,667). The large curving, windows allow sightlines to the horizon from the seated positions.

    Sea Ray 400 Fly salon
    Sea Ray refers to this salon as the “Sunroom” and we can see why. Cabinets can be in a choice of Chestnut (shown), Prestige Cherry Gloss or Pecan Woodline Matte, and both compliment the wood decking.
    Sea Ray 400 Fly aft doors
    Triple wide opening aft doors blends the inside with the outside. Dual couches create a conversational social area.

    A wine chiller, a staple of any entertaining yacht, will keep the whites and blushes at a preset temperature.


    Having the galley on the main deck solves a multitude of problems, especially from an entertainment standpoint. It’s now not necessary to continually traipse up and down stairs to serve hors d'oeuvres to guests.This galley is at once luxurious and functional. Only high-end appliances are used and abundant storage is available throughout. Hardwoods for the cabinetry are matching those throughout the boat, as are the solid surface counters. An acrylic “backsplash” separates the galley from the adjacent sofa and it’s etched with a Sea Ray “swoosh” matching the curvature of the salon windows.

    An exhaust vent

    is located adjacent to the stove. An optional opening sliding window can be added to this side and next to the helm ($3,333 P&S), to add to the natural ventilation of the cooking area.

    The refrigerator/freezer

    is dual-voltage, allowing it to be used without the need for shore power or the standard generator running. A two-burner flush-mounted stove is forward. The stainless steel sink is aft and includes covers to increase the usable counter space.

    The galley is on the main deck, allowing for the chef to remain in the social areas at all times. Notice the exhaust vent just adjacent to the stove.

    Lower Helm

    The standard lower helm station is located to starboard on the main deck. There’s excellent visibility through a set of massive front windows with narrow mullions. Spray and rain are cleared with two self-parking windshield wipers and defrosters are standard. Canvas/mesh windshield shades can be installed ($2,000) to take the strain off the air conditioning when the Fly 400 is not in use.The side windows have optional sliding opening windows ($3,333 P&S) for ventilation. Heating and air conditioning vents are in the center of the panel venting directly at the operator for maximum coverage. A stereo remote is to the left side of the helm, allowing for control from both the captain and companion.A 4” (10.16 cm) SmartCraft display is located front and center in the panel and a single Raymarine Es 128 12” (30.5 cm) GPS/Chartplotter display with an integrated 4 kW radar is to the side. Add a second display as an option ($7,083). An airline-style compass is at the top of the panel.Additional electronic options include an autopilot ($4,667) and an open array radar antenna ($5,333).

    Greenhouse effect is kept at bay from the opening sunroof and side portlight. When climate control takes precedence, then vents directly in front of the operator provide heat or cooling as desired.

    Sea Ray never forgets the details… Here we see a leather-wrapped and stainless steel steering wheel. The vinyl is hand-stitched with contrast thread. The joinery alongside appears impeccable.
    Sea Ray 400 Fly v-drive
    The Fly 400 comes with the Cummins diesel V-Drive package as well as the Cummins joystick, which are shown in this picture.

    Lower Deck

    Sea Ray created a two-stateroom layout, both full-beam, but added an option of selecting either one head or two ($15,000 VacuFlush is included with the second head). The second head comes at the expense of losing some of the open space in the forward master stateroom. Carpet runners from Sunbrella ($1,667) cover the carpet in the lower areas.


    Both staterooms come with a compliment of pillows, rich Fabrics, curtains for the hull side windows, a 12V stereo with Bluetooth connectivity, in-deck storage, central vac and Chestnut wood cabinetry as standard. Flooring is carpeted throughout. Bedding with comforters, sheets and pillows are supplied as standard. A 16,000 BTU reverse-cycle air-handling system provides cooling or heating as desired.

    Sea Ray 400 Fly accommodations layout
    The Sea Ray Fly 400 is a two-stateroom yacht offered with either a single, or dual head layout. Note that Sea Ray has used the tubular "beam-me-up-Scotty" type of shower stall arrangement which has a semi-circular acrylic sliding shower door, which opens up space when not used for bathing.
    Sea Ray 400 Fly running shot
    The main deck isn’t alone in benefiting from natural light. Huge hull side windows brighten up the two staterooms while the tint ensures privacy.

    Master Stateroom

    The master stateroom is located forward and a queen island berth highlights the berth area. Expansive windows run the length of the stateroom to both sides and an overhead hatch is directly over the head of the berth, allowing the owners to fall asleep to a view of the sky.

    The master stateroom receives plenty of natural light thanks to large hull side windows and an overhead hatch.

    Two Heads are Better than One

    The master stateroom includes so much closet space that Sea Ray can take up some of it, along with the available open space, to add a second head, making this stateroom en suite. Even with this option, there’s plenty of storage space left, and the remaining cabinetry even includes a stool in front of a pull-out vanity drawer that will be much appreciated by the lady of the house. Add a safe in the aft stateroom ($625) for added security if the owner plans to throw a lot of parties. A flatscreen TV is included as standard.

    Sea Ray 400 Fly vanity drawer
    A pull-out vanity drawer will be a welcome feature for getting ready for a night out at the waterfront restaurant.

    Guest Stateroom

    The guest stateroom sleeps two in separate berths that will slide together for those times when couples, rather than siblings, are utilizing the space. A third person can be accommodated by utilizing the settee as a berth. If more storage is needed, swap out the settee with a storage cabinet ($3,333).

    Sea Ray 400 Fly guest cabin
    Guests are accommodated in twin berths that can come together when/if desired. Seen here is the optional storage cabinet. A settee is standard.

    The head features a separate walk-in shower that is enclosed in a curved acrylic surround. A standard VacuFlush toilet, mirrored vanity, a medicine cabinet, and Sea Ray towels are all included. Flooring is simulated teak tile.

    Sea Ray 400 Fly head
    The curved acrylic shower stalls add a modern look in addition to increasing the useable space in the head itself. Notice the good use of space with the storage over the hull side window.

    Operational Features

    Standard power

    for the Sea Ray Fly 400 is a pair of 6.7 HO Cummins QSB 480 with V-drives and no options are available.

    Fuel capacity

    is 320 gallons (1,211 L), held in a pair of aluminum tanks, both fitted with electric shutoffs and mechanical sending units. An optional patented Dynamic Running Surface ($3,708) trim tab system automatically adjusts the running surfaces for maximum performance throughout the operating parameters.

    The electrical system

    includes a 120V/40 Amp/12V charger/converter. Add an inverter as an option ($6,167). We’d also add the optional oil change system ($1,500) if selecting V-Drives.

    Sea Ray 400 Fly running shot
    High safety rails to the sides make an easy and safe transition to the bow, even when underway.


    We tested the Sea Ray Fly 400 with a standard pair of Cummins 6.7 480’s turning 23x25.5 pitch, 4-blade Acme propellers. With an empty weight of 37,500 lbs. (17,010 kg), 62% fuel and three people onboard, we estimated our test weight at 40,105 lbs. (18,191 kg).In the heavy chop of our test day, our top speed was 29.7 kts reached at 3340 rpm. That speed produced a fuel burn of 50.1 gph, allowing the Fly 400 to keep going for 170.7 nm. Best economy was achieved at 3000 rpm and 25.4 kts. At that speed, the fuel burn dropped to 41.5 gph and the range opened up to 176.5 nm. Now it’s important to note that we conducted this test in choppy conditions with winds blowing up to 20 mph. To achieve these numbers in those conditions is impressive indeed.


    It was good to be able to test in these windy conditions as it gave a good real-world example of what the Sea Ray Fly 400 has to offer. She gave a well-mannered ride, only offering up some hull slap at full speed and directly into the chop. Pulled back even slightly improved the ride and comfort level. This bodes well as it’s unlikely that anyone will be running this yacht continually at full speed, regardless of conditions. If we took the seas just off the bow, then things improved even more and she had a more docile ride to her as she bridged the gap between the crests much better, and with a mostly level attitude. Of course beam seas and following were even more comfortable. As for spray, well physics can’t stop that from happening and as long as a bow throws water, wind will pick it up and blow it back. But that’s what windshield wipers are for. For those needing to quench their desire for being on the bow when underway, it will become necessary to pick and choose the conditions on which to do that and avoid heavy chop and a course that takes them on the bow.


    The Sea Ray Fly 400 comes nicely equipped for a base price of $790,065. Among the first choices to make for options is hull color. Anything but white will add $6,250 to that base price. Fully loaded “our way” has the Fly 400 topping out at $1.19m.


    We’ve long been convinced of the benefits regarding the Sundancer line, the design is pretty much synonymous with the brand, and now it’s plain to see that Sea Ray isn’t one to sit idly by and watch the success pass it by. By adding a flying bridge to an existing design, there’s a commonality of components that make this model a cost effective solution for Sea Ray and those benefits are passed onto the customer. This, along with the changes we have seen at Sea Ray for the last two years or so with the introduction of the L Series of large yachts and the new SLX sizzle at the sportboat end, have put the industry on notice that Sea Ray plans on being as competitive as ever.
