Crownline 21 SS 2007 vs Crownline 235 CCR 2007: Same Brand, Different Boat

The Crownline 21 SS 2007 vs Crownline 235 CCR 2007 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 235 CCR 2007 measures 25,0 feet overall (2007), giving it roughly 5,0 additional feet of deck space compared to the Crownline 21 SS 2007 at 20,0 feet (2007). Weight tells a clearer story for trailering families: the Crownline 235 CCR 2007 tips the scales at 4 400 lbs - 700 lbs less than the Crownline 21 SS 2007 at 3 700 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.

Both boats share a closely matched power ceiling - 320 hp for the Crownline 21 SS 2007 and 320 hp for the Crownline 235 CCR 2007. 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 235 CCR 2007 carries 77 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 21 SS 2007 is rated for 10 passengers, while the Crownline 235 CCR 2007 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crownline 21 SS 2007 could be the deciding factor.

Bottom line: Choose the Crownline 21 SS 2007 if your priority is putting more people on the water - it handles 10 passengers and at 20,0 ft it has the deck room to back that rating up comfortably. The Crownline 235 CCR 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.

Crownline 21 SS 2007 vs Crownline 235 CCR 2007 - Common Questions

Which is the larger boat - the Crownline 21 SS 2007 or the Crownline 235 CCR 2007?
The Crownline 235 CCR 2007 is the longer of the two at 25,0 feet overall. The Crownline 21 SS 2007 comes in at 20,0 feet, making it roughly 5,0 ft shorter - a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer - the Crownline 21 SS 2007 or the Crownline 235 CCR 2007?
For trailering, the Crownline 21 SS 2007 has the edge at 3 700 lbs dry weight versus 4 400 lbs for the Crownline 235 CCR 2007. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
How many people can each boat hold?
The Crownline 21 SS 2007 is Coast Guard rated for 10 passengers, while the Crownline 235 CCR 2007 is certified for 9. Note that legal capacity and comfortable capacity aren't always the same thing - on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Crownline 21 SS 2007 and Crownline 235 CCR 2007 share an 102 in. (2.59 m) beam - meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
Which boat has the larger fuel tank - the Crownline 21 SS 2007 or the Crownline 235 CCR 2007?
The Crownline 235 CCR 2007 has the bigger tank at 77 gallons, versus 41 gallons on the Crownline 21 SS 2007. That 36-gallon difference translates to roughly 108–180 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Crownline 21 SS 2007 and Crownline 235 CCR 2007 from the same manufacturer?
Yes - both the Crownline 21 SS 2007 and the Crownline 235 CCR 2007 are built by Crownline. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
