Matching a modified vee Crownline 21 SS 2010 against a deep vee Crownline 236 SC 2013 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.

On paper these two are close siblings in the size department — Crownline 21 SS 2010 at 20,8 ft versus Crownline 236 SC 2013 at 23,5 ft. At 37 lbs and 48 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 2010 and 320 hp for the Crownline 236 SC 2013. 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 236 SC 2013 carries 45 gallons versus 41 gallons in the Crownline 21 SS 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 236 SC 2013 is rated for 8 passengers, while the Crownline 21 SS 2010 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crownline 236 SC 2013 could be the deciding factor.
