When two boats share the same hull type — in this case both the Cobalt Boats 37 2009 and the Cobalt Boats R5 2013 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 37 2009 measures 37,5 feet overall (2009), giving it roughly 11,8 additional feet of deck space compared to the Cobalt Boats R5 2013 at 25,7 feet (2013). Weight tells a clearer story for trailering families: the Cobalt Boats 37 2009 tips the scales at 2 116 lbs — 1 628 lbs more than the Cobalt Boats R5 2013 at 488 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 R5 2013 tops out at 8 hp. Engine specs for the Cobalt Boats 37 2009 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Cobalt Boats 37 2009 carries 23 gallons versus 5 gallons in the Cobalt Boats R5 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 37 2009 is rated for 11 passengers, while the Cobalt Boats R5 2013 caps at 2. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Cobalt Boats 37 2009 could be the deciding factor.
