Cobalt Boats 255 2006 vs Cobalt Boats 373 2011 — Same Brand, Different Boat

The Cobalt Boats 255 2006 vs Cobalt Boats 373 2011 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.

Size is the most obvious dividing line here. The Cobalt Boats 373 2011 measures 37,5 feet overall (2011), giving it roughly 12,5 additional feet of deck space compared to the Cobalt Boats 255 2006 at 25,0 feet (2006). Weight tells a clearer story for trailering families: the Cobalt Boats 373 2011 tips the scales at 2 116 lbs — 1 622 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.

Both boats share a closely matched power ceiling — 425 hp for the Cobalt Boats 255 2006 and 425 hp for the Cobalt Boats 373 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 255 2006 carries 73 gallons versus 23 gallons in the Cobalt Boats 373 2011. 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 255 2006 is rated for 14 passengers, while the Cobalt Boats 373 2011 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Cobalt Boats 255 2006 could be the deciding factor.

Bottom line: Choose the Cobalt Boats 255 2006 if your priority is putting more people on the water — it handles 14 passengers and at 25,0 ft it has the deck room to back that rating up comfortably. The Cobalt Boats 373 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 11 that costs less to run day-to-day.

Cobalt Boats 255 2006 vs Cobalt Boats 373 2011 — Common Questions

Which is the larger boat — the Cobalt Boats 255 2006 or the Cobalt Boats 373 2011?
The Cobalt Boats 373 2011 is the longer of the two at 37,5 feet overall. The Cobalt Boats 255 2006 comes in at 25,0 feet, making it roughly 12,5 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Cobalt Boats 255 2006 or the Cobalt Boats 373 2011?
For trailering, the Cobalt Boats 255 2006 has the edge at 494 lbs dry weight versus 2 116 lbs for the Cobalt Boats 373 2011. 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.
How many people can each boat hold?
The Cobalt Boats 255 2006 is Coast Guard rated for 14 passengers, while the Cobalt Boats 373 2011 is certified for 11. 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.
Which boat is wider, and does it affect trailering?
The Cobalt Boats 373 2011 measures 144" wide, compared to 102" for the Cobalt Boats 255 2006. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Cobalt Boats 255 2006 or the Cobalt Boats 373 2011?
The Cobalt Boats 255 2006 has the bigger tank at 73 gallons, versus 23 gallons on the Cobalt Boats 373 2011. That 50-gallon difference translates to roughly 150–250 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Cobalt Boats 255 2006 and Cobalt Boats 373 2011 from the same manufacturer?
Yes — both the Cobalt Boats 255 2006 and the Cobalt Boats 373 2011 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.
