The Cobalt Boats 336 2013 vs Cobalt Boats R8 2022 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

The Cobalt Boats 336 2013 carries a rated maximum of 2 hp. Engine data for the Cobalt Boats R8 2022 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Cobalt Boats 336 2013 carries 154 gallons versus 8 gallons in the Cobalt Boats R8 2022. 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 336 2013 is rated for 10 passengers, while the Cobalt Boats R8 2022 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Cobalt Boats 336 2013 could be the deciding factor.
