Captain's Report

Sea Ray 400 Sundancer idle shot

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


The new 400 Sundancer 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 counter tops.

Sea Ray 400 Sundancer profile shot

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

Features Inspection



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

L-shaped seating

that wraps around a pedestal table to starboard opposes a single seat 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. And the entire cockpit can be enclosed with isinglass ($4,167) for three season boating.

Protection is offered

from an optional overhead SureShade extendable awning ($12,500). 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 ($1,808).

Sea Ray 400 Sundancer l shaped seating

L-shaped seating surrounds a triangular pedestal table. A single seat lies opposite. A pair of carry-on coolers store under the seat.

Sea Ray 400 Sundancer extended hard top

The extended hardtop provides ample protection, but for those days when more is needed, an optional SureShade awning extends electrically from the aft section of the overhead.

Sea Ray 400 Sundancer platform stairs

Stairs remain flush to the platform until it is lowered, and then they automatically deploy. Note the steps are located directly aft of the transom door for production boats to allow for a PWC to be stored on the platform (500 lb. capacity).

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 are a pair of storage drawers on stainless steel sliders.
It requires either the extended platform or hydraulic option 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 ($1,667).

Sea Ray 400 Sundancer out door 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 ($4,883) that can be covered in teak ($5,833) or a hydraulic platform ($46,667). The optional hydraulic platform has a 500 lb. (226.8 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” (1.12 m) 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 ($1,667) includes a transom remote.


The comfort level extends fully forward to the bow where a standard multi-position sun pad offers sun worshipers a place to relax. Side rails, fabricated from 316 stainless steel, allow the area to be safely used, even when the 400 Sundancer 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.

Too Much Sun?

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



A combination of large windows and an opening sunroof work together with the large aft doors to blue 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, a gaming system to port, DVD storage and the yacht is pre-wired for coax. A surround sound system ($2,500) can be installed and will include a DVD player, amplifier and component speakers.
The hardwood flooring looks great, but for added protection, carpet runners from Sunbrella can be added ($1,667). The carpet runners cover the carpet in the lower areas but not on the salon floors.

Sea Ray 400 Sundancer 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 Sundancer 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 or Pecan Woodline Matte, and both compliment the wood decking.

Sea Ray 400 Sundancer aft doors

Triple wide opening aft doors blends the inside with the outside. Dual couches create a conversational social area.

Sea Ray 400 Sundancer wine chiller

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.

Sea Ray 400 Sundancer running shot

Huge windows with narrow mullions allow for plenty of natural light as well as great sightlines from the helm.

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.


Both staterooms come with a compliment of pillows, Allante Fabric, curtains for the hull side windows, 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 Sundancer accommodations layout

The 400 Sundancer is a two-stateroom yacht offered with either a single or dual head layout. Not 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 Sundancer 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.

Two Heads are Better than One

The master 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 (Note, the cabinetry with the stool and pull-out vanity drawer is part of the standard configuration and goes away when the second head is ordered) 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 master ($625) for added security when having a lot of parties (Note the safe is located in the aft stateroom locker). A flatscreen TV is included as standard.

Sea Ray 400 Sundancer stateroom

As with the main deck, copious amounts of natural light and dark woods are the continuing theme.

Sea Ray 400 Sundancer vanity

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 Sundancer guest stateroom

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 Sundancer 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

The 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 400 Sundancer 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 gas sterndrive

propulsion system is standard and Sea Ray also includes an Axius joystick, allowing for precision controllability at and around the dock. If optional V-Drives are chosen, then we’d add on the optional bow thruster ($12,500) as well. If further control is desired, a V Drive boat can be configured with a Cummins joystick docking system that combines the propulsion engines and a bow thruster to effortlessly maneuver the boat
A 4” (10.16 cm) SmartCraft display is located front and center in the panel and a single Raymarine e125 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).

Sea Ray 400 Sundancer helm

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 400 Sundancer steering wheel

Sea Ray never forgets the details… Here we see a leather-wrapped and chromed steering wheel. The vinyl is hand-stitched with contrast thread. The joinery alongside appears impeccable.

Sea Ray 400 Sundancer joystick

Digital throttle and shift (DTS) and Axius joystick are both standard on the 400 Sundancer. This picture actually shows the V-Drive controls as well as the Cummins Joystick.

Sea Ray 400 Sundancer running shot

The 400 Sundancer is powered with engines ranging from 370-hp to 480-hp.

Standard power

for the Sea Ray 400 Sundancer is a pair of 430-hp 8.2 MAGs turning BIII outdrives. These can be swapped out for a pair of 425-hp 8.2 Horizon V-drives ($4,167) for those that aren’t keen on sterndrives.
For diesel options, choose from a pair of 370-hp 4.2L T3s with BRIII outdrives ($68,333) or 6.7 HO Cummins QSB 480 with V-drives ($48,417).

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 Sundancer 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 400 Sundancer with a pair of Cummins QSB 480s turning 23x26.5 pitch, 4-blade Acme propellers. With an empty weight of 12,935 lbs. (5,867 kg), 37% fuel and three people onboard, we estimated our test weight at 14,660 lbs. (6,650 kg).

Top speed

was 31.9 kts reached at 3325 rpm. That speed produced a fuel burn of 50.1 gph allowing the 400 Sundancer to keep going for 183.2 nm. Best economy was achieved at 2750 rpm and 25.3 kts. At that speed, the fuel burn dropped to 35.4 gph and the range opened up to 205.5 nm.
Now it’s important to note that we conducted this test in snotty 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 400 Sundancer 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.
When 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 seas 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 400 Sundancer comes nicely equipped for a base price of $707,435. With the optional engine and fully loaded she’ll top out at $784,661.


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.
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.
