Detailed Evaluation & Buyer Recommendation

Cobalt Boats 255 2006 vs Cobalt Boats 276 2009 — Same Brand, Different Boat

The Cobalt Boats 255 2006 vs Cobalt Boats 276 2009 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

The Cobalt Boats 255 2006 carries a rated maximum of 425 hp. Engine data for the Cobalt Boats 276 2009 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Cobalt Boats 276 2009 carries 95 gallons versus 73 gallons in the Cobalt Boats 255 2006.
