Cobalt Boats 276 2013 vs Cobalt Boats 303 2011 — A Close Look at Two Deep Vees

When two boats share the same hull type — in this case both the Cobalt Boats 276 2013 and the Cobalt Boats 303 2011 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 2013 at 27,5 ft versus Cobalt Boats 303 2011 at 29,8 ft. Weight tells a clearer story for trailering families: the Cobalt Boats 303 2011 tips the scales at 1 111 lbs — 1 056 lbs less than the Cobalt Boats 276 2013 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.

Both boats share a closely matched power ceiling — 430 hp for the Cobalt Boats 276 2013 and 430 hp for the Cobalt Boats 303 2011. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Cobalt Boats 276 2013 carries 95 gallons versus 15 gallons in the Cobalt Boats 303 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Bottom line: The Cobalt Boats 303 2011 at 29,8 ft is the right call if deck space, comfort, and entertaining are top of your list. The Cobalt Boats 276 2013 at 27,5 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.

Cobalt Boats 276 2013 vs Cobalt Boats 303 2011 — Common Questions

The Cobalt Boats 303 2011 is the longer of the two at 29,8 feet overall. The Cobalt Boats 276 2013 comes in at 27,5 feet, making it roughly 2,3 ft shorter — a meaningful difference in deck room and overall on-water presence.
