Detailed Evaluation & Buyer Recommendation

Cobalt Boats A25 2010 vs Cobalt Boats A28 2013 — A Close Look at Two Deep Vees

When two boats share the same hull type — in this case both the Cobalt Boats A25 2010 and the Cobalt Boats A28 2013 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 A25 2010 at 25,5 ft versus Cobalt Boats A28 2013 at 28,5 ft. Weight tells a clearer story for trailering families: the Cobalt Boats A25 2010 tips the scales at 5 125 lbs — 4 579 lbs more than the Cobalt Boats A28 2013 at 546 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 power gap is worth calling out. Rated to 430 hp, the Cobalt Boats A28 2013 has a 130-hp advantage over the Cobalt Boats A25 2010's 300-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Cobalt Boats A28 2013 carries 9 gallons versus 5 gallons in the Cobalt Boats A25 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

The Cobalt Boats A25 2010 is rated for up to 15 people. Passenger data for the Cobalt Boats A28 2013 wasn't available.

Bottom line: The Cobalt Boats A28 2013 at 28,5 ft is the right call if deck space, comfort, and entertaining are top of your list. The Cobalt Boats A25 2010 at 25,5 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.
