Cobalt 343: BoatTEST Review

Reviewed by Jeff Hammond

Overview

Cobalt has long been recognized for producing world-class sport boats, though it has not been widely known in the high-performance segment—until now. The Cobalt 343 represents a significant advancement for the brand, emerging from three years of dedicated research and development. This model is designed to combine high-performance capabilities with the luxury and attention to detail that Cobalt is known for, aiming to deliver an exhilarating and refined boating experience.

Exterior Design and Deck Features

The Cobalt 343 features a thoughtfully designed exterior that prioritizes both performance and comfort. Wide side decks facilitate easy movement around the boat, while a fender locker equipped with gas-assisted lifts provides convenient storage. The deck layout includes two individual sun pads and two stern benches separated by a spacious walk-through, with double-hinged seats offering ample storage beneath. Practical amenities such as an inflator for water toys and a tool kit are integrated into the port bench compartment, which also houses battery switches, main breakers, and canvas pole storage. The two-level transom and swim platform provide close access to the water, protected by a wraparound stainless steel bar that serves as a handhold and dock guard. A dive-style ladder deploys effortlessly via a lever, and stainless steel vents and fins ensure fresh air circulation to the engine compartment. Additional features include a swim shower and water hookup located in the starboard compartment.

Interior Living Spaces

Inside the cabin, the Cobalt 343 offers a level of refinement more commonly found on mega-yachts or aircraft. The cabin door is a solid, non-sliding design that opens to reveal a port-to-starboard V-shaped bench seating area. A flat-panel television is mounted in one corner, providing entertainment options for evening relaxation. The enclosed head includes a port-a-potty, sink, and vanity, ensuring privacy and convenience. At the stern, rear-facing bench seats create a spacious conversation area, with the double-hinged seating providing cavernous storage below.

Helm and Controls

The helm station of the 343 is designed with a futuristic, cockpit-like layout. To the left of the helm, a bank of rocker switches is complemented by two rows of gauges, including water and air temperature indicators as well as digital depth gauges. The helm features Gaffrig instrumentation and LaVorsi precision engine controls, allowing the operator precise command over the vessel. The pilot seat is equipped with electric lifts that enable a quick transition from seated to standing driving positions. This ergonomic and technologically advanced helm setup enhances control and comfort during operation.

Power and Performance

Performance on the Cobalt 343 is driven by twin 496 V8 engines, each producing 425 horsepower. The boat incorporates Cobalt's first-ever step-tall hull design, augmented by a padded keel and a knot's transom, which together contribute to exceptional stability and a smooth ride even in choppy seas. The hull design ensures the boat remains firmly planted on the water during straight runs and maintains excellent grip through turns. The engines feature a closed cooling system, an air-actuated single-point water drain system with an included air pump, and a single serpentine belt driving all components. The engine control module utilizes a motor oil microprocessor to optimize fuel mixture, knock control, and ignition timing independently for each cylinder, resulting in precise and efficient performance. The 343 measures 35 feet 4 inches in length overall with a beam of 9 feet 8 inches and a draft of 28 inches with the drive up, extending to 37 inches with the drive down. It weighs approximately 10,200 pounds with twin CERN drives and carries 200 gallons of fuel, meeting yacht certification standards. Economically, the boat cruises at 3,500 RPM, achieving 40.9 miles per hour with a fuel consumption of 31.5 gallons per hour, offering a range of 234 miles on a full tank. At wide-open throttle, it reaches 5,100 RPM and a top speed of 62.4 miles per hour.

Conclusion

The Cobalt 343 successfully blends high-performance engineering with the luxury and meticulous craftsmanship that the brand is known for. Its innovative hull design and powerful twin engines deliver thrilling speed and handling, while the thoughtfully designed interior and exterior spaces provide comfort and convenience for extended outings. With a top speed exceeding 60 miles per hour and a comprehensive suite of amenities, the 343 stands out as one of the most luxurious high-performance sport boats currently available.
