Cobalt Boats of Neodesha, Kansas has built its reputation as one of North America's premier builders of luxury sport boats, prized for hand laid fiberglass construction, sharp deep V hulls, premium upholstery, and a level of fit and finish that few production builders match. The 343 sits at the very top of the Cobalt range as the flagship performance cruiser, pairing genuine offshore capability with the comfort and craftsmanship the brand is known for.

The Cobalt 343 is a high performance express cruiser that combines a large, beautifully appointed open cockpit with an enclosed cabin and head below. This example is powered by twin MerCruiser 496 MAG HO 425 horsepower gas engines on stern drives with through prop exhaust, delivering effortless cruising and exhilarating top end performance. The cockpit features wraparound Ultraleather seating, a full instrumentation helm, a refreshment centre, and an extended swim platform, while the cabin below sleeps two and includes an enclosed head.
