Matching a deep vee Crownline 21 SS 2013 against a modified vee Crownline 240 EX 2010 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

Size is the most obvious dividing line here. The Crownline 240 EX 2010 measures 24,5 feet overall (2010), giving it roughly 3,7 additional feet of deck space compared to the Crownline 21 SS 2013 at 20,8 feet (2013). At 37 lbs and 5 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

Both boats share a closely matched power ceiling — 320 hp for the Crownline 21 SS 2013 and 320 hp for the Crownline 240 EX 2010. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Crownline 21 SS 2013 carries 41 gallons versus 5 gallons in the Crownline 240 EX 2010. 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 Crownline 240 EX 2010 is rated for 13 passengers, while the Crownline 21 SS 2013 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crownline 240 EX 2010 could be the deciding factor.
