When two boats share the same hull type — in this case both the Cobalt Boats 243 2012 and the Cobalt Boats 323 2012 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?

Size is the most obvious dividing line here. The Cobalt Boats 323 2012 measures 32,8 feet overall (2012), giving it roughly 8,9 additional feet of deck space compared to the Cobalt Boats 243 2012 at 23,9 feet (2012). At 46 lbs and 123 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The power gap is worth calling out. Rated to 430 hp, the Cobalt Boats 243 2012 has a 428-hp advantage over the Cobalt Boats 323 2012's 2-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 323 2012 carries 174 gallons versus 5 gallons in the Cobalt Boats 243 2012. 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 243 2012 is rated for 13 passengers, while the Cobalt Boats 323 2012 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Cobalt Boats 243 2012 could be the deciding factor.
