When two boats share the same hull type — in this case both the Cobalt Boats 242WSS 2013 and the Cobalt Boats 303 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 303 2010 measures 29,8 feet overall (2010), giving it roughly 5,8 additional feet of deck space compared to the Cobalt Boats 242WSS 2013 at 23,9 feet (2013). Weight tells a clearer story for trailering families: the Cobalt Boats 303 2010 tips the scales at 1 111 lbs — 1 065 lbs less than the Cobalt Boats 242WSS 2013 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 power gap is worth calling out. Rated to 430 hp, the Cobalt Boats 242WSS 2013 has a 130-hp advantage over the Cobalt Boats 303 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 303 2010 carries 15 gallons versus 5 gallons in the Cobalt Boats 242WSS 2013. 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 242WSS 2013 is rated for 13 passengers, while the Cobalt Boats 303 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 242WSS 2013 could be the deciding factor.
