Cobalt Boats 255 2006 vs Cobalt Boats A25 2010 - Boat Spec Comparison

Q: Which is the larger boat — the Cobalt Boats 255 2006 or the Cobalt Boats A25 2010?

The Cobalt Boats A25 2010 is the longer of the two at 25,5 feet overall. The Cobalt Boats 255 2006 comes in at 25,0 feet, making it roughly 0,5 ft shorter — a meaningful difference in deck room and overall on-water presence.

Q: Which is easier to trailer — the Cobalt Boats 255 2006 or the Cobalt Boats A25 2010?

For trailering, the Cobalt Boats 255 2006 has the edge at 494 lbs dry weight versus 5 125 lbs for the Cobalt Boats A25 2010. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.

Q: Which boat can handle a bigger outboard?

The Cobalt Boats 255 2006 is rated to a maximum of 425 hp, giving it the larger power ceiling. The Cobalt Boats A25 2010 tops out at 300 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.

Q: How many people can each boat hold?

The Cobalt Boats 255 2006 is Coast Guard rated for 14 passengers, while the Cobalt Boats A25 2010 is certified for 15. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.

Q: Do these boats require an oversize trailer permit to tow on US highways?

Both the Cobalt Boats 255 2006 and Cobalt Boats A25 2010 share an 8 ft. 6 in. (2.59 m) beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.

Q: Which boat has the larger fuel tank — the Cobalt Boats 255 2006 or the Cobalt Boats A25 2010?

The Cobalt Boats 255 2006 has the bigger tank at 73 gallons, versus 5 gallons on the Cobalt Boats A25 2010. That 68-gallon difference translates to roughly 204–340 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Cobalt Boats 255 2006 and Cobalt Boats A25 2010 from the same manufacturer?

Yes — both the Cobalt Boats 255 2006 and the Cobalt Boats A25 2010 are built by Cobalt Boats. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.

Detailed Evaluation & Buyer Recommendation

Cobalt Boats 255 2006 vs Cobalt Boats A25 2010 — Same Brand, Different Boat

The Cobalt Boats 255 2006 vs Cobalt Boats A25 2010 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.

On paper these two are close siblings in the size department — Cobalt Boats 255 2006 at 25,0 ft versus Cobalt Boats A25 2010 at 25,5 ft. Weight tells a clearer story for trailering families: the Cobalt Boats A25 2010 tips the scales at 5 125 lbs — 4 631 lbs less than the Cobalt Boats 255 2006 at 494 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 425 hp, the Cobalt Boats 255 2006 has a 125-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 255 2006 carries 73 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.

For family outings this is probably the sharpest distinction between the two. The Cobalt Boats A25 2010 is rated for 15 passengers, while the Cobalt Boats 255 2006 caps at 14. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Cobalt Boats A25 2010 could be the deciding factor.

Bottom line: Choose the Cobalt Boats A25 2010 if your priority is putting more people on the water — it handles 15 passengers and at 25,5 ft it has the deck room to back that rating up comfortably. The Cobalt Boats 255 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 14 that costs less to run day-to-day.
