When two boats share the same hull type — in this case both the Cobalt Boats 242 2009 and the Cobalt Boats 302 2010 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 302 2010 measures 29,8 feet overall (2010), giving it roughly 5,8 additional feet of deck space compared to the Cobalt Boats 242 2009 at 23,9 feet (2009). Weight tells a clearer story for trailering families: the Cobalt Boats 302 2010 tips the scales at 988 lbs — 942 lbs less than the Cobalt Boats 242 2009 at 46 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 Cobalt Boats 302 2010 tops out at 300 hp. Engine specs for the Cobalt Boats 242 2009 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Cobalt Boats 302 2010 carries 15 gallons versus 5 gallons in the Cobalt Boats 242 2009. 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 242 2009 is rated for 13 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 242 2009 could be the deciding factor.
