Cobalt Boats 302 2010 vs Cobalt Boats 343 2006 — Same Brand, Different Boat

The Cobalt Boats 302 2010 vs Cobalt Boats 343 2006 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 343 2006 measures 35,0 feet overall (2006), giving it roughly 5,3 additional feet of deck space compared to the Cobalt Boats 302 2010 at 29,8 feet (2010). Weight tells a clearer story for trailering families: the Cobalt Boats 343 2006 tips the scales at 1 175 lbs — 187 lbs less than the Cobalt Boats 302 2010 at 988 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 500 hp, the Cobalt Boats 343 2006 has a 200-hp advantage over the Cobalt Boats 302 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 302 2010 carries 15 gallons versus 2 gallons in the Cobalt Boats 343 2006. 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 343 2006 is rated for 10 passengers, while the Cobalt Boats 302 2010 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Cobalt Boats 343 2006 could be the deciding factor.

Bottom line: Choose the Cobalt Boats 343 2006 if your priority is putting more people on the water — it handles 10 passengers and at 35,0 ft it has the deck room to back that rating up comfortably. The Cobalt Boats 302 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.

Cobalt Boats 302 2010 vs Cobalt Boats 343 2006 — Common Questions

Which is the larger boat — the Cobalt Boats 302 2010 or the Cobalt Boats 343 2006?
The Cobalt Boats 343 2006 is the longer of the two at 35,0 feet overall. The Cobalt Boats 302 2010 comes in at 29,8 feet, making it roughly 5,3 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Cobalt Boats 302 2010 or the Cobalt Boats 343 2006?
For trailering, the Cobalt Boats 302 2010 has the edge at 988 lbs dry weight versus 1 175 lbs for the Cobalt Boats 343 2006. 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.
Which boat can handle a bigger outboard?
The Cobalt Boats 343 2006 is rated to a maximum of 500 hp, giving it the larger power ceiling. The Cobalt Boats 302 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.
How many people can each boat hold?
The Cobalt Boats 302 2010 is Coast Guard rated for 9 passengers, while the Cobalt Boats 343 2006 is certified for 10. 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 302 2010 measures 119" wide, compared to 116" for the Cobalt Boats 343 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 302 2010 or the Cobalt Boats 343 2006?
The Cobalt Boats 302 2010 has the bigger tank at 15 gallons, versus 2 gallons on the Cobalt Boats 343 2006. That 13-gallon difference translates to roughly 39–65 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Cobalt Boats 302 2010 and Cobalt Boats 343 2006 from the same manufacturer?
Yes — both the Cobalt Boats 302 2010 and the Cobalt Boats 343 2006 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.
