Cobalt 35' 4'' 343

Simply an unforgettable driving experience on a cabin speedboat with a cruising speed of 35 knots and a maximum speed of 48 knots. At the same time, unprecedented low fuel consumption, at cruising speed only 50 liters per hour for two engines in total.

At the heart of the Cobalt 343's response to a long list of owner requirements lies the hull. A stepped hull, and Cobalt was far from the first in the industry to bring such a hull into its fleet. Only when Cobalt engineers were convinced that their design could guarantee, without question, total safety and control to match the hull's obvious advantages, did the 343 come off the drawing boards. There came too longstanding Cobalt benchmarks: the matchless Cobalt extended running surface, a full-length keel pad for better tracking, reverse chines, a notched transom decreasing drag from the outdrive, and a gentle, gentle ride among all that horsepower.

The Cobalt 343 with twin Volvo Penta D6 engines is a rare and highly efficient high-performance setup. While the 343 is primarily known for its aggressive big-block V8 gasoline setups, diesel variants offer incredible mid-range torque, exceptional range, and unmatched fuel efficiency, typically cruising around 35 knots while reaching top speeds near 48 knots

The boat has just undergone a complete renovation in 2026 - hull wrapping, polishing, new soft teak, new seats leather, new Raymarine Axiom+ chart plotter plus 3D sonar, new Fusion stereo with speakers, underwater lights, new antifouling, new batteries, all new LED lights, complete DPH drives renovation with new bearings and seals.
