2010 COBALT 276, CLOSEOUT! 2010 Cobalt 276 (Ebony/White) In describing the newest incarnation of Cobalt boat-building philosophy, Cobalt engineers speak of heft, of beefiness, of strength both real and perceived. The 276 just looks substantial. At the same time, the 276 s exterior design those long, long lines offer a new expression of Cobalt classicism. In its combination of easy grace and masterfully channeled power, the 276 extends the definition of a large runabout in the Mediterranean mold, a transitional boat borrowing much of the style, even more of the substance of a performance cruiser. More about those lines: Aft, the transom swoops down, where a fresh design for the finned engine vents uses stainless steel to complement the illusion that this boat never really does ride at anchor.
