Sea Ray Sundancer 350 Coupe running

The Sea Ray Sundancer 350 Coupe with an optional extended swim platform.

Sea Ray Sundancer 350 Coupe running

The Sundancer 350 Coupe’s hardtop and solid windows provide a dry ride for the helmsman, even when the black vent above the windshield is open to let in fresh air.

Sea Ray Sundancer 350 Coupe deck plan

The deck of the Sundancer 350 Coupe combines watersports off the swim platform with a social place around the settee table, open to conversation with the helm, and a bonus sun pad for lounging on the bow.


The Sea Ray Sundancer 350 Coupe gives owners of smaller Sea Rays something to aspire to. By making this boat a large dayboat entertaining platform that can be used for watersports, Sea Ray is appealing to a wide audience. Also, she fills a niche between large bowriders and bigger express cruisers that have a dearth of competitors.

Sea Ray Sundancer 350 Coupe sun roof

Open the powered sunroof to let in fresh air.

Major Features

  • Hardtop with retractable sunroof
  • Mechanized retractable canvas cover over aft salon
  • Swim platform galley/grille
  • Quiet Ride sound control
  • Swivel helm seat
  • 16,000 BTU A/C
  • Electric windlass and ground tackle

Sea Ray Sundancer 350 Coupe helm bench seat

The helm bench seat base swivels so the skipper can engage with guests in the salon.

Sea Ray Sundancer 350 Coupe running

With no cavitation in hard turns, the Sundancer 350 Coupe slices through a wake.


The Sundancer 350 Coupe has a LOA of 37’6” (11.43 m), a beam of 11’4” (3.45 m), and a draft of 40” (102 cm). With an empty weight of 18,792 lbs. (8,525 kg), 107 gallons (405 L) of fuel aboard and no water in the 40-gallon (151 L) tank, plus three people onboard, we had an estimated test weight of 20,039 lbs. (9,090 kg).

With the optional upgrade to twin gas-powered 380-hp Mercury 8.2 MAG ECT Seacore Bravo IIIx with Axius control, we reached our top speed of 36.8 mph at 4750 rpm.

Sea Ray Sundancer 350 Coupe running

We found the Sundancer 350 Coupe to be a relatively dry ride.

Best cruise came in at 4000 rpm and 31 mph. It was at that speed that the 40.5 gph fuel burn translated into 0.8 mpg and a range of 128.2 nautical miles, all while still holding back a 10-percent reserve of the boat’s 214-gallon (810 L) total fuel capacity.


We had an average time to plane of 6.7 seconds, accelerated to 20 mph in 11.2 and 30 in 22.3 seconds.

Sea Ray Sundancer 350 Coupe running

The bowrise at speed does not affect visibility adversely.


Maneuvering around the dock, the Sundancer 350 Coupe fitted with an optional bow thruster and Axius propulsion system joystick was spot on. For those stepping up to a bigger boat like this and are concerned about maneuvering, this package should eliminate those concerns. More experienced boaters may only need the bow thruster, or no aid at all.

Sea Ray Sundancer 350 Coupe joystick

The joystick-operated Axius propulsion system and 380-hp engine upgrade added $36k to our base boat price of $412,990.

Sea Ray Sundancer 350 Coupe running

The Sundancer 350 Coupe gets up on plane quickly.

We had mild conditions on test day, so little chance to comment on how she handles chop, but crossing wakes showed how her bow presents a dry ride by dispersing spray. We did put the boat through its paces for turn angles, etc…and at speed the Sundancer 350 Coupe does ride high with a bowrise of approximately 11-degrees, and visibility is still fine.

Boat Inspection

The Stern

The flexibility of this boat begins at the stern swim platform. An optional electric grill is built into the transom and is accessed from the swim platform. However, an extended swim platform, with or without teak decking, or even one that lowers into the water, is optional.

Sea Ray Sundancer 350 Coupe swim platform

With the extended swim platform we measured 5’ (1.52 m) behind the grill. There is also a 5” (12.7 cm) step-up to pass through the plexi gate.

Sea Ray Sundancer 350 Coupe swim platform

Our test boat had the optional $4,042 extended swim platform, but not with teak decking, which would add $1,823 more just to plank the platform and the base teak deck option of $5,388.

Sea Ray Sundancer 350 Coupe grill

The grill option is accessed from the swim platform.

The grill enclosure has a small stainless steel sink with cover to match the solid countertop. The grill backs the L-shaped aft salon seating area. The whole structure is hinged, and doubles as the hydraulically-controlled engine cover.

Sea Ray Sundancer 350 Coupe storage

Storage drawers below the grille are handy for things like shore cords, especially when the shore cord connection is in the locker immediately on the left.

Sea Ray Sundancer 350 Coupe shore cord

The shore cord connection is in a small locker attached to the grill. The locker includes the washdown faucet and shore-water fill.

The Engine Room

Once the engine hatch is open, it reveals the optional power plant in our test boat: twin gas-powered MerCruiser V-8, 380-hp (8.2 L) engines with SeaCore Bravo III sterndrives. 350-hp engines are standard, but bigger engines, inboard drives, or even twin 354-hp MerCruiser V-drive diesels are available. All in all, there are eight engine/propulsion packages to choose from.

Our test boat had the optional Axius Propulsion system that includes joystick and SmartCraft Digital throttle and shift. Forward of the engines is a shelf that holds an optional generator that matches the fuel type (gas or diesel), and electrical options (120v/60 or 220v/50) chosen.

Sea Ray Sundancer 350 Coupe

Fluid check points and fills are on the front of the engine.

Sea Ray Sundancer 350 Coupe generator

Forward is the optional gas generator ($17,035) next to the batteries. Aluminum fuel tanks are outboard, port and starboard.

Sea Ray Sundancer 350 Coupe color codes

Mercury color codes the covers to match maintenance functions.


Enter the cockpit from the swim platform via a plexi door-gate on the starboard side. The first thing we noticed were the molded-in steps that access the starboard side deck for going forward.

Sea Ray Sundancer 350 Coupe mat

At the base of the molded in steps is an optional $1,385 snap-in mat for the cockpit.

Just to the left is an L-shaped settee surrounding a solid wood table on a double pedestal.

Sea Ray Sundancer 350 Coupe pedestal table

The pedestal table can be adjusted for height or removed completely. Teak decking is a $5,388 option.

Sea Ray Sundancer 350 Coupe table

The table can drop down, and with the addition of cushions becomes a sunning couch.

Sea Ray Sundancer 350 Coupe

Flexible design allows the table to stow away in the engine hatch cubby where Captain Steve has placed his hand. There is also storage under the settee cushions.

Sea Ray Sundancer 350 Coupe canvas

The Sundancer 350 Coupe has a motorized canvas cover option that retracts into the hardtop and shades the cockpit table with push-button ease when deployed for those uber-sunny days.

Sea Ray Sundancer 350 Coupe settee

There’s another settee to the right of the cockpit table with an optional cockpit refrigerator below the seat.

Sea Ray Sundancer 350 Coupe cockpit

The entire cockpit melds with the helm area. The helm seat swivels to add seating to the cockpit and inclusion for the skipper.

Over the starboard settee is an optional flatscreen TV on a swivel mount.

The Bow

The bow of the Sundancer 350 Coupe has a welcome sun pad to relax on. To get there, follow the molded-in steps from the aft deck, up to the side deck.

Sea Ray Sundancer 350 Coupe sidedecks

These side decks may be a bit narrow at 6” (15.2 cm). However, the handrails are generous and well placed to help forward movement in safety.

Sea Ray Sundancer 350 Coupe bow seating

Bow seating backrests are adjustable. Music speakers and cupholders are ubiquitous on this boat.


Just forward of the sun pad is the recessed anchor station. The standard electric windlass has a cover on a gas shock to protect it when not in use. The anchor is a galvanized plow, with foot pedal controls just to the side. This boat has a cleat to take the standing load off the windlass.

Sea Ray Sundancer 350 Coupe anchor rode

An all chain anchor rode and a remote controlled spotlight are additional available options.

Below Decks

Sea Ray Sundancer 350 Coupe accommodations

Accommodations for six, two in the master berth forward, two in the main cabin by converting the table into a berth, and two in the guest cabin aft, make the Sundancer 350 Coupe a capable family cruiser.

We enter the cabin through a sliding hatch next to the helm and step down four wooden steps with non-skid inserts.

Sea Ray Sundancer 350 Coupe clearance

The 6’4” (1.93 m) overhead clearance gives the cabin an airy feel. Access to the guest cabin is to the right of the companionway stairs.

Sea Ray Sundancer 350 Coupe galley

The chestnut wood finish of the galley cabinets is carried throughout the interior.

The galley is immediately to starboard with microwave, two-burner induction cooktop, solid surface counters, and a refrigerator below. Side windows in the cabin do not open but there is an option to add more opening ports, such as the one in the galley.

Sea Ray Sundancer 350 Coupe galley

The galley sink cabinet has pull-out pantry style drawers.


Sea Ray Sundancer 350 Coupe cabin

The floor to ceiling cabinet to starboard hides a privacy curtain that can separate the forward berth from the main cabin. Note the curtain track on the overhead between the tall cabinets.

Forward are settees to port and starboard flanking a removable dining table. The dining table drops down and the settees convert into bunks for additional sleeping accommodations.

Sea Ray Sundancer 350 Coupe dining table

The cabin dining table has a fold-out leaf for additional eating space. When lowered it acts as a platform for a berth. It can also be removed completely.

Master Berth

In the bow, forward of the settees, is the master with the berth angled for easy access. At the entrance, there are a few steps up where the headroom is adequate over the berth. There are overhead storage lockers around the bunk and a hatch for natural light and ventilation. A hanging locker to port separates the master berth from the port settee.

Sea Ray Sundancer 350 Coupe master berth

The angled master berth has a mirror forward to reflect light from the skylight onto the warm wood finish of the overhead storage compartments surrounding the berth.

Sea Ray Sundancer 350 Coupe port settee

Flip down the backrest of the port settee to access the electrical panel.

Sea Ray Sundancer 350 Coupe panel

The electrical panel has a small shelf above it.

Just aft of the port settee is a 32” (81.3 cm) flat screen TV mounted on an adjustable bracket. The cabin’s hanging locker has the Fusion stereo system controls inside.


The head compartment is to port of the accommodation ladder. It’s a VacuFlush head with a separate shower stall behind a glass door. In addition to the power vent, there’s an opening port light for ventilation and a hull side window for natural light. Teak-simulated flooring, medicine cabinet, a full length mirror on the back of the head door, vessel sink, and a wood surface countertop complete the space.

Sea Ray Sundancer 350 Coupe basin

There is a soft roll up curtain over the sidelight above the vessel sink in the head which can be dropped down for privacy. Above that is a front-to-back mirrored medicine chest.

Sea Ray Sundancer 350 Coupe shower

A shower stall separated from the rest of the head by a glass door is rare in this size boat.

Sea Ray Sundancer 350 Coupe teak

Teak-simulated floorboards facilitate drainage in the head and shower.

Guest Accommodations

The standard cabin layout has a separate guest cabin next to the accommodation ladder with a lockable privacy door. When entering there is a small settee on the right with a hanging locker next to it and storage lockers above and below the settee.

On the left are twin bunks, each measuring 6’4” (1.93 m) long and 1’9” (.53 m) wide.

Sea Ray Sundancer 350 Coupe beds

There is an insert that goes between the bunks in the guest cabin to combine them into a 6’4” x 4’5” (1.93 m x 1.35 m) double berth.

There is also an optional guest cabin layout where the twin berths are replaced by an L-shaped seat that converts to a sleeper.

Sea Ray Sundancer 350 Coupe guest cabin

The guest cabin has a hanging locker next to the settee with a central vac system on the panel below the seat. Carpet trims the toe kick over wood floors.

Opening ports on both sides of the cabin let in light and fresh air. The bunks have 2’10” (.86 m) overhead clearance above them. A 24” (60.95 cm) flatscreen TV graces the forward bulkhead.


One of the main features of the Sundancer 350 Coupe is that the helm is an enclosed space with a solid windshield and side windows under the hardtop. This feature is welcome when the weather kicks up or when there is a need for the optional cockpit air conditioner/heater. A comfortable bench seat is to port.

Sea Ray Sundancer 350 Coupe

The single piece windshield with Pantograph wipers provides good visibility for the helmsman. Note the fixed light in the dash that helps to illuminate the interior.

Sea Ray Sundancer 350 Coupe helm bench seat

One of Captain Steve’s favorite features is the port helm bench with adjustable backrest.

The helm area has a fresh air vent and a retractable sunroof in the hardtop as well as vent side windows. The helm chair is a double-wide bench with a flip-up bolster if you choose to stand while driving.

Sea Ray Sundancer 350 Coupe windows

Vent windows on either side of the helm slide down to open and come in handy during maneuvers.

Sea Ray Sundancer 350 Coupe helm

The double wide helm seat has a single bolster. A footrest below the wheel is welcome when seated. The black hatch to the main cabin slides open and stores behind the helm.

The magnetic compass sits atop the center of the instrument panel. There are cup holders over the 9” (22.86 cm) touchscreen chart plotter on the left, not the ideal location for a drink to slosh around, but we found it perfect for stowing a cell phone and handheld VHF.

Fusion stereo controls are to the left of the wheel. There are gauges up and to the right, and a tilt wheel in the center.

Sea Ray Sundancer 350 Coupe gauges

Sea Ray calls their combination of analog and digital gauges SmartCraft multi-gauges.

Sea Ray Sundancer 350 Coupe axius

The Axius Propulsion system joystick and bow thruster controls are to the right.

Sea Ray Sundancer 350 Coupe rockers

A long single row of electrical rockers provides a centralized location to manage most systems on the boat.


Sea Ray uses robots to cut hull openings, leading to more consistent quality construction. They also employ “Quiet Ride” technology to sound insulate their boats. WOT decibel levels never exceeded 88 dBa during our test. We were not running the unshielded genset at the time.

World Cat 280CC-X


Base price is $412,990.

Sea Ray Sundancer 350 Coupe running

The coupe version of the Sundancer 350 Coupe packs a lot of functionality into a 35’ (16.15 m) family cruiser.


The Sea Ray Sundancer 350 Coupe doesn’t feel crowded because many features are dual purpose. We think Sea Ray has done a good job combining storage and functionality on this boat.

There are a lot of options available on this boat, which can be a good thing. However, this many options can be confusing, particularly when some options require prerequisite options. A good example of this is joystick control, which requires the bow thruster option as well.

When powered by twin gas engines she is less expensive to operate than with diesels, which get better mileage, but, in our view, not enough to pay for their price differential.

The coupe design makes a cozy refuge when it is cool or rainy. The Sea Ray Sundancer 350 Coupe should attract move-up boaters wanting a boat that they can cruise in three seasons.
