When two boats share the same hull type — in this case both the Cobalt Boats 276 2009 and the Cobalt Boats 303 2010 are deep vee designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

On paper these two are close siblings in the size department — Cobalt Boats 276 2009 at 27,5 ft versus Cobalt Boats 303 2010 at 29,8 ft. Weight tells a clearer story for trailering families: the Cobalt Boats 303 2010 tips the scales at 1 111 lbs — 1 056 lbs less than the Cobalt Boats 276 2009 at 55 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The Cobalt Boats 303 2010 tops out at 300 hp. Engine specs for the Cobalt Boats 276 2009 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Cobalt Boats 276 2009 carries 95 gallons versus 15 gallons in the Cobalt Boats 303 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
