When two boats share the same hull type — in this case both the Cobalt Boats 276 2010 and the Cobalt Boats 373 2011 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 373 2011 measures 37,5 feet overall (2011), giving it roughly 10,0 additional feet of deck space compared to the Cobalt Boats 276 2010 at 27,5 feet (2010). Weight tells a clearer story for trailering families: the Cobalt Boats 373 2011 tips the scales at 2 116 lbs — 2 061 lbs less than the Cobalt Boats 276 2010 at 55 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 425 hp, the Cobalt Boats 373 2011 has a 50-hp advantage over the Cobalt Boats 276 2010's 375-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 276 2010 carries 95 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.
