Cobalt 30SC profile

The 30SC is Cobalt’s largest outboard day boat. It includes optional power from Yamaha and Mercury from twin 250-hosepower outboards to twin 350-horsepower outboards.

Cobalt 30SC running

The 30SC is Cobalt’s largest outboard day boat. With a “Yacht Certified” passenger certification, it can carry as many family and friends as the owner deems safe.


The Cobalt 30SC is designed, engineered, and built to provide recreational day boating for a variety of purposes. The effective overall interior layout provides easy flow for socializing underway or on the beach.

Cobalt 30SC running

The Cobalt 30SC hull features a sharp bow entry to cut through chop, hard chines that force water out and provide stability.

Major Features

  • Outboard Propulsion. The option of twin 250-horsepower, twin 300-horsepower or twin 350-horsepower Yamaha or Mercury outboards gives the Cobalt 30SC plenty of power, and the space that an inboard sterndrive would have taken is utilized for additional seating and storage.
  • Glass Helm. Cobalt designed the 30SC with dual Garmin GPSMAP® 741xs multifunction touchscreen displays that allow the operator to custom configure the boat’s data.
  • Adjustable Helm Seat Bolster. When the bolster is in the up position, the operator sits well above the windshield for 360-degrees of uninterrupted view. With the bolster lowered, the helm seat provides the operator protection behind the windshield.
  • Flexible Forward Seating. The forward-facing seating in front of the port and starboard consoles have drop-down armrests. The port side wraps around to the bow which offers aft facing forward seating.
  • Convertible Companion Seating. The companion seat back can be adjusted for forward-facing seating for two or it can be reversed to deliver aft facing lounge seating that can provide observer seating for tow-sports.
  • Aft Sun Pad. The aft sun pad has an adjustable backrest that can be configured to be forward-facing seating or aft-facing seating.
  • Extended Running Surface. By extending the running surface of the hull, the Cobalt 30SC comes on plane quicker and with less bow-rise.
  • Quality Construction and Materials. From the waterproof Deutsch connectors to the gas assist struts on all hatch covers, Cobalt uses the finest components and the latest proven construction methodologies.
  • Resale Value. Cobalt boats have traditionally maintained their desirability over time. The Cobalt 30SC should hold its value better than many brands.
  • Warranty. Cobalt stands behind the 30SC with a Ten-Year Structural Warranty, a Five-Year Bow to Stern Component Warranty and a Three-Year Gelcoat Finish Warranty.

Performance has not tested this boat so we can offer no first-hand information of performance and handling.

However, Yamaha has tested the boat, and reports that she has a dry weight of 6,900 lbs. (3,130 kg) and the tested weight was 9,089 lbs. (4,123 kg). The twin Yamaha F250s used 15’1.4 x 19” ss props. Yamaha reports a top of 56.3 mph, and a best cruise of 22.3 mph at 3500 rpm, getting 1.9 mpg.

Optional engines include twin Mercury 300-hp Verados and twin Mercury Verado 350s. Twin 300 and 350s are also available from Yamaha. We will be interested in seeing how the new Mercury V8s perform in this application.

The question begs: How does the performance of the Cobalt 30SC with twin outboards stack up against the Cobalt R30 with sterndrives. At some point we hope to be able to tests them and find out.

Boat Inspection

Cobalt 30SC lines

The 30SC has the distinctive lines that have come to define the Cobalt brand. Nine colors plus white are optional for her hull.


Cobalt 30SC anchor

The optional stainless steel anchor with all chain and windlass is an important option. Note the stainless steel bow roller and scuff plate.

This boat comes without a standard anchor. While the mission of this is watersports and day boating, owners should not forget that all boats must have at least one anchor suitable for holding the vessel securely. The type of bottom – mud, grass, sand or rock – requires different styles of anchors to be most effective.

Cobalt 30SC windlass

Shown is the optional windlass and all-chain rode mounted inside the anchor locker.

Cobalt 30SC bow seating

The forward seating has room for at least four adults sitting comfortably. The port side seating is a lounger. There is an available dinette table that mounts in the floor receptacle and an optional cushion to form a forward sun pad. A sun pad filler cushion is also available.

Cobalt 30SC port seat

Both the port side and starboard side have cut-outs below the padded coaming for drink holders and stereo speakers. Note the stainless steel grab rails built into the padded backrests.

Grab Rails. Well placed grab rails are an important safety item required by ABYC standards, but Cobalt has done a particularly good job of integrating them into the padded backrests in an attractive manner.

Cobalt 30SC forward seats

Both forward facing seats are deep and also have flip-down armrests for a secure feeling while underway. Cobalt uses multi-density foams for added comfort and support in its seats.

Cobalt 30SC bow storage

There is storage under the forward seating. We’d like to see a drain put in this compartment along with foam insulation so it can be used as a cooler.

Cobalt 30SC side seat

The starboard side seat opens to reveal copious storage inside the starboard side helm console. An optional refrigerator can be placed here which will greatly cut down on the storage capacity.

Port Console

Cobalt 30SC console

The port side console has recessed storage for incidentals. The companion seating is double wide and has a padded armrest, drink holders, a 12-volt outlet, and a USP port built into the bulwark. The head door swings out to the right and is cut away on top to aid access.


Cobalt 30SC porta potti

The 30SC comes standard with a pump-out Porta-Potti. Shown here is the optional electric VacuFlush head and macerator, and opening portlight.

Helm Console

Cobalt 30SC helm console

The helm console is ergonomically designed with custom stitched leather-like materials that give it an automotive styling. Real leather is on the ss steering wheel. The joystick is optional. The 40 oz. sea grass deck carpeting is optional.

Cobalt 30SC garmin gps

Twin Garmin GPSMAP® 741xs multifunction displays (one comes standard) are seamlessly integrated into the dash to provide a highly useful glass helm on this boat.

Cobalt 30SC detail

The port side detail of the helm shows the systems lit-when-on push-button switches, the stereo controls, and the ignition switches. In this case, they are Mercury ignition switches.

Cobalt 30SC switches

On the starboard side are additional system switches, optional Lenco tab controls, and the engines monitor display. In this case, the Mercury VesselView display.

Horn Switch. It is hard to tell which switch is the horn. We like to see the horn switch set apart either by location or by color for easy identification when quickly needed.

Cobalt 30SC engine control

Shown is the engine control binnacle. It appears well positioned to operate while seated and using the armrest.

The Mercury Joystick Piloting for Outboards or Yamaha Optimus 360 Joystick. The joystick position is the same for both systems, forward of the control binnacle and raised. It is well positioned for operating standing up, which is the preferred position when close in maneuvering or docking.

Cobalt 30SC steering wheel

The leather wrapped and stainless steel wheel has a multi-position tilt base that comes standard.

Cobalt 30SC helm seat

The helm seat is double wide with a fold-up bolster to boost the operator’s view to be above the windshield header for a 360-degree uninterrupted view.

Cobalt 30SC refrigerator

Cobalt offers an optional refrigerator that fits into the helm console and opens into the windshield walkthrough.

Aft Cockpit

Cobalt 30SC port seating

The port side seating backrest can be adjusted to forward and back.

Cobalt 30SC port seat

In the forward most position it becomes a double wide sun pad and lounger.

Cobalt 30SC aft bench

The aft bench seating can be set up to offer forward-facing seating for several passengers. Note the wide transom walkthrough.

Cobalt 30SC aft cockpit

In the aft cockpit we can see the seats that are ideal for watching tow activities.

Dinette Table. Cobalt offers an optional galley and dinette table that fits in the receptacle in the aft cockpit floor. The galley replaces the jump seat behind the port lounge seating.

Cobalt 30SC

The aft bench seat backrest can be positioned forward to create a wide lounger/sun pad.

Cobalt 30SC cockpit seating

The seating in the Cobalt 30SC cockpit is versatile.


Cobalt 30SC aft lounge

Under the aft lounger/sun pad is storage. Note the gas assist struts on both sides.

Cobalt 30SC boarding platforms

On both sides of the engines, the Cobalt 30SC has boarding platforms that are the right height for boarding and debarking on a floating dock. The painted optional white color of the outboards is a $5,663 option.

Aft-Facing Transom Seating. Passengers should never occupy aft-facing transom seating while underway on any sportboat. They should only be used when the boat is at rest and the engine turned off. With the seat back forward this becomes a lounger or sun pad.

Cobalt 30SC step

On the starboard side is a built-in boarding step. Note the grab rail on the outboard side.

Re-Boarding Ladder. ABYC standards call for all boats to have a re-boarding ladder deployable by someone in the water. It must reach a minimum of 22” (.56 m) below the waterline.

Swim Platform

Perhaps the largest drawback to outboard power for a sportboat is the elimination of an across-the-transom swim platform such as those found on sterndrive-powered boats. These platforms are an ideal place to launch watersports of all kinds. The Cobalt 30SC has two small platforms to each side of its twin engine outboard installation.

People who are active enthusiasts should seriously consider Cobalt’s R30 which is sterndrive powered and has a full-width swim platform. It is a particularly functional one – quite the opposite of what is found on the 30SC.

Cobalt 30SC water sports

As can be seen in this image, there is considerable room in front of the outboard engines to organize watersports boards and toys, but the access to the water is restricted.

Cobalt 30SC life style

The Cobalt R30 has proven itself over the years and has both a full-beam swim platform and patented submersible step that is unique in the industry.

Notable Details

Cobalt 30SC clips

Quick Release Fender Clips. Cobalt places stainless steel sockets placed in strategic locations for fender deployment. We like the system and Cobalt is one of the few builders who use them.

Cobalt 30SC hinges

Double Knuckle Hinges. The cushioned seat tops open with double knuckle hinges to allow hands free access to the storage below.

Trailer. Cobalt does not sell or manufacture trailers. The local Cobalt dealer should be able to match your boat and needs to the trailer that will best suit.

Hull Colors

Cobalt 30SC blue colorCobalt 30SC red color

The Cobalt 30SC comes in 10 different colors, including white. Buyers can mix and match these colors on the hullside, hull bottom, edge stripe and boot stripe. The optional cost for the nine colors is $3,444.


Following is a brief summary of the warranty description on the Cobalt 30SC. We always recommend that consumers read the fine print of all boat and engine warranties. Cobalt’s warranty is one of the best in class.

Ten-Year Structural Warranty. Covers hull and deck structure, joints, bulkheads, floor, transom, stringers, motor mounts. It is fully transferable.

Five-Year Bow to Stern Component Warranty. All components manufactured or purchased. Including all canvas and all upholstery. It is fully transferable.

Three-Year Gelcoat Finish Warranty. Fully transferable.

Engine Warranty. These are warranted by the engine manufacturer and the standard warranty is for 3 years.

The base MSRP price of the Cobalt 30SC is $210,612 with twin 250-hp Mercury Verados. The options above that we recommend come to $62,622, bringing the total MSRP for this boat to $273,234.

Cobalt 30SC

We will be interested in seeing how the Cobalt 30SC performs with the new Mercury V8 Verados.


Cobalt has a long-standing reputation for superior quality. Like many manufactures, they have recently placed a higher emphasis on the outboard day-boat segment. The 30SC is the largest outboard boat to be introduced to Cobalt’s dedicated devotees and aspirants.

In our opinion, the most important thing that consumers must make up their mind about is the stern platform, and which is the best configuration for one’s application – sterndrive or outboard. Entering into that equation is also the fact that the Cobalt R30, a similar-size boat, is about $22,000 less money.

Cobalt is now owned by the same company that owns Malibu and Axius ski/wake boats, so dealers for both brands now have the option of carrying both. This can only put more Cobalts on the water.
