Crownline 255 SS 2015 vs Crownline 320 LS 2007 - Boat Spec Comparison

Q: Which is the larger boat — the Crownline 255 SS 2015 or the Crownline 320 LS 2007?

The Crownline 320 LS 2007 is the longer of the two at 32,0 feet overall. The Crownline 255 SS 2015 comes in at 26,0 feet, making it roughly 6,0 ft shorter — a meaningful difference in deck room and overall on-water presence.

Q: Which boat can handle a bigger outboard?

The Crownline 320 LS 2007 is rated to a maximum of 640 hp, giving it the larger power ceiling. The Crownline 255 SS 2015 tops out at 300 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.

Q: How many people can each boat hold?

The Crownline 255 SS 2015 is Coast Guard rated for 7 passengers, while the Crownline 320 LS 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.

Q: Which boat has the larger fuel tank — the Crownline 255 SS 2015 or the Crownline 320 LS 2007?

The Crownline 320 LS 2007 has the bigger tank at 139 gallons, versus 55 gallons on the Crownline 255 SS 2015. That 84-gallon difference translates to roughly 252–420 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Crownline 255 SS 2015 and Crownline 320 LS 2007 from the same manufacturer?

Yes — both the Crownline 255 SS 2015 and the Crownline 320 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 255 SS 2015 vs Crownline 320 LS 2007 — Same Brand, Different Boat

The Crownline 255 SS 2015 vs Crownline 320 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.

The power gap is worth calling out. Rated to 640 hp, the Crownline 320 LS 2007 has a 340-hp advantage over the Crownline 255 SS 2015's 300-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 320 LS 2007 carries 139 gallons versus 55 gallons in the Crownline 255 SS 2015. 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 320 LS 2007 is rated for 9 passengers, while the Crownline 255 SS 2015 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crownline 320 LS 2007 could be the deciding factor.

Bottom line: Choose the Crownline 320 LS 2007 if your priority is putting more people on the water — it handles 9 passengers and at 32,0 ft it has the deck room to back that rating up comfortably. The Crownline 255 SS 2015 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
