Crownline 21 SS 2010 vs Crownline 230 LS 2007 - Boat Spec Comparison

Q: Which is the larger boat — the Crownline 21 SS 2010 or the Crownline 230 LS 2007?

The Crownline 230 LS 2007 is the longer of the two at 24,0 feet overall. The Crownline 21 SS 2010 comes in at 20,8 feet, making it roughly 3,2 ft shorter — a meaningful difference in deck room and overall on-water presence.

Q: Which is easier to trailer — the Crownline 21 SS 2010 or the Crownline 230 LS 2007?

For trailering, the Crownline 21 SS 2010 has the edge at 37 lbs dry weight versus 43 lbs for the Crownline 230 LS 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.

Q: How many people can each boat hold?

The Crownline 21 SS 2010 is Coast Guard rated for 1 passengers, while the Crownline 230 LS 2007 is certified for 11. 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.

Q: Do these boats require an oversize trailer permit to tow on US highways?

Both the Crownline 21 SS 2010 and Crownline 230 LS 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.

Q: Which boat has the larger fuel tank — the Crownline 21 SS 2010 or the Crownline 230 LS 2007?

The Crownline 230 LS 2007 has the bigger tank at 62 gallons, versus 41 gallons on the Crownline 21 SS 2010. That 21-gallon difference translates to roughly 63–105 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Crownline 21 SS 2010 and Crownline 230 LS 2007 from the same manufacturer?

Yes — both the Crownline 21 SS 2010 and the Crownline 230 LS 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.

Detailed Evaluation & Buyer Recommendation

Crownline 21 SS 2010 vs Crownline 230 LS 2007 — Same Brand, Different Boat

The Crownline 21 SS 2010 vs Crownline 230 LS 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 230 LS 2007 measures 24,0 feet overall (2007), giving it roughly 3,2 additional feet of deck space compared to the Crownline 21 SS 2010 at 20,8 feet (2010). At 37 lbs and 43 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 230 LS 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 230 LS 2007 carries 62 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 230 LS 2007 is rated for 11 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 230 LS 2007 could be the deciding factor.

Bottom line: Choose the Crownline 230 LS 2007 if your priority is putting more people on the water — it handles 11 passengers and at 24,0 ft it has the deck room to back that rating up comfortably. The Crownline 21 SS 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
