Cobalt A28: BoatTEST Review
Overview
The Cobalt 828 is a thoughtfully designed sport boat that builds upon the success of the popular A-25 by extending the length by three feet, strategically added to the center for enhanced space and functionality. This model exemplifies Cobalt's commitment to uncompromising quality, with superior fit and finish and a host of premium amenities. The 828 offers a blend of elegance and versatility, making it a standout in the high-end sport boat category.
Exterior Design and Deck Features
Externally, the Cobalt 828 showcases meticulous attention to detail. Stainless steel speaker grills with a honeycomb pattern are integrated into quilted upholstery bulwarks, complemented by recessed stainless drink holders. The cockpit walkthrough features a storage hatch with gas-assist struts and soundproofing beneath, allowing it to be opened even with the carpet in place. Additional conveniences include a stereo remote and pull-out shower adjacent to the walkthrough. The boat is equipped with a distinctive stainless steel arch supporting a custom-made bimini top with turnbuckle tension adjustment and integrated LED courtesy lights. The aft sun pad is highly versatile, allowing users to switch between chaise lounge and bench seating configurations with ease, while the observer seat flips to form an aft-facing chaise lounge. The bow seating area includes a full-length lounger to port and a convertible lounge to starboard, where a hinged filler cushion can be deployed to create additional lounging space. Storage compartments are thoughtfully integrated throughout, including for the bow filler cushion, fire extinguisher, navigation light, and ski tow pylon. The starboard side features an entertainment center with a recessed single basin sink, a removable cutting surface that doubles as a serving tray, and optional teak cutting board. A cockpit refrigerator is also available. The boat is fitted with a hydraulic swim platform that operates in conjunction with the outdrive position, allowing for smooth deployment and retraction.
Interior Living Spaces and Amenities
The interior amenities reflect Cobalt's high standards. The helm area features an oversized, custom-embroidered, quilted seat with a padded flip-up bolster designed for all-day comfort. The helm console is finished in soft-touch materials with earth tones to minimize glare, and includes dual multifunction gauges flanking a removable GPS mount. Push-button switches are backlit when activated, and the premium leather and stainless steel steering wheel is mounted on a tilt base. A hatch over the fender storage locker is secured by a magnetic catch and designed with contoured sides for drainage. The head compartment is equipped with a porcelain electric flush toilet with dockside pump-out, a solid surface countertop with integrated sink, an electric vent fan, a frosted overhead skylight, and a mirror on the door’s interior. The cockpit also includes a glove box housing a premium sound system with Sirius satellite radio and a speaker selector switch.
Power and Performance
Powered by the latest Volvo Penta V8 430 engine paired with a dual-prop outdrive, the Cobalt 828 delivers impressive performance and responsiveness. The boat measures 28 feet 6 inches in length overall with a beam of 8 feet 6 inches and an empty weight of 5,460 pounds. With 30 gallons of fuel and two people aboard, the test weight was 6,060 pounds. The top speed reached 53.1 mph at 6,000 rpm, consuming 34 gallons per hour and providing a range of 126 miles. The most efficient cruising speed was 28 mph at 3,500 rpm, burning 9.35 gallons per hour, which translates to a range of 243 miles and an endurance of nearly nine hours with a 10% fuel reserve. Acceleration was notably brisk, with a time to plane of 3.7 seconds, reaching 20 mph in 5.9 seconds and 30 mph in 8.6 seconds. The high torque of the Volvo Penta engine contributed to superior mid-range response and quick throttle advancement, enhancing the overall driving experience.
Operational Features and Storage
Operational convenience is evident throughout the 828. The helm seat’s ergonomic design and padded bolster enhance comfort during extended use. The helm console’s digital engine controls and lighted push-button switches simplify operation. The electric lift engine hatch allows easy access to the engine compartment without obstructing cockpit movement. The engine bay is spacious, facilitating maintenance and inspection. Under the port cockpit seat, the battery switch, main circuit breakers, and jumper terminals are accessible and include provisions for inflating water toys. The bow features a flush-mounted hatch over the deck floor, providing access to the windlass and anchor roller, with hull-mounted docking lights positioned on either side for improved visibility.
Conclusion
The Cobalt 828 exemplifies the brand’s dedication to quality, detail, and performance. Its thoughtful design, premium materials, and versatile features combine to create a sport boat that is both functional and visually impressive. The integration of the Volvo Penta V8 430 engine enhances its performance credentials, delivering quick acceleration and efficient cruising.
