Crownline 21 SS 2011 vs Crownline 325 SCR 2010 — Same Brand, Different Boat

Matching a modified vee Crownline 21 SS 2011 against a deep vee Crownline 325 SCR 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 325 SCR 2010 measures 32,4 feet overall (2010), giving it roughly 11,6 additional feet of deck space compared to the Crownline 21 SS 2011 at 20,8 feet (2011). At 37 lbs and 11 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.

The power gap is worth calling out. Rated to 750 hp, the Crownline 325 SCR 2010 has a 430-hp advantage over the Crownline 21 SS 2011's 320-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Crownline 325 SCR 2010 carries 139 gallons versus 41 gallons in the Crownline 21 SS 2011. 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 325 SCR 2010 is rated for 9 passengers, while the Crownline 21 SS 2011 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crownline 325 SCR 2010 could be the deciding factor.

Bottom line: Choose the Crownline 325 SCR 2010 if your priority is putting more people on the water — it handles 9 passengers and at 32,4 ft it has the deck room to back that rating up comfortably. The Crownline 21 SS 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.

Crownline 21 SS 2011 vs Crownline 325 SCR 2010 — Common Questions

Which is the larger boat — the Crownline 21 SS 2011 or the Crownline 325 SCR 2010?
The Crownline 325 SCR 2010 is the longer of the two at 32,4 feet overall. The Crownline 21 SS 2011 comes in at 20,8 feet, making it roughly 11,6 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Crownline 21 SS 2011 or the Crownline 325 SCR 2010?
For trailering, the Crownline 325 SCR 2010 has the edge at 11 lbs dry weight versus 37 lbs for the Crownline 21 SS 2011. 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.
Which boat can handle a bigger outboard?
The Crownline 325 SCR 2010 is rated to a maximum of 750 hp, giving it the larger power ceiling. The Crownline 21 SS 2011 tops out at 320 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Crownline 21 SS 2011 is Coast Guard rated for 1 passengers, while the Crownline 325 SCR 2010 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.
Which boat is wider, and does it affect trailering?
The Crownline 325 SCR 2010 measures 116" wide, compared to 102" for the Crownline 21 SS 2011. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Crownline 21 SS 2011 or the Crownline 325 SCR 2010?
The Crownline 325 SCR 2010 has the bigger tank at 139 gallons, versus 41 gallons on the Crownline 21 SS 2011. That 98-gallon difference translates to roughly 294–490 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Crownline 21 SS 2011 and Crownline 325 SCR 2010 from the same manufacturer?
Yes — both the Crownline 21 SS 2011 and the Crownline 325 SCR 2010 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.
