The Crownline 21 SS 2007 vs Crownline 240 EX 2005 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.

Size is the most obvious dividing line here. The Crownline 240 EX 2005 measures 22,0 feet overall (2005), giving it roughly 20,0 additional feet of deck space compared to the Crownline 21 SS 2007 at 2,0 feet (2007). 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 2007 and 320 hp for the Crownline 240 EX 2005. 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 240 EX 2005 carries 62 gallons versus 41 gallons in the Crownline 21 SS 2007. 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 2005 is rated for 13 passengers, while the Crownline 21 SS 2007 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 2005 could be the deciding factor.
