Crownline 315 SCR 2009 vs Crownline 320 LS 2007 — Same Brand, Different Boat

The Crownline 315 SCR 2009 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.

On paper these two are close siblings in the size department — Crownline 315 SCR 2009 at 32,0 ft versus Crownline 320 LS 2007 at 32,0 ft. At 11 lbs and 95 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 315 SCR 2009 has a 110-hp advantage over the Crownline 320 LS 2007's 640-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 139 gal and 139 gal — so range won't be a tiebreaker here.

Both boats are rated for 9 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: Performance buyers should lean toward the Crownline 315 SCR 2009 and its 750-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Crownline 320 LS 2007 with its 640-hp rating is the more economical daily driver.

Crownline 315 SCR 2009 vs Crownline 320 LS 2007 — Common Questions

Which is the larger boat — the Crownline 315 SCR 2009 or the Crownline 320 LS 2007?
The Crownline 320 LS 2007 is the longer of the two at 32,0 feet overall. The Crownline 315 SCR 2009 comes in at 32,0 feet, making it roughly 0,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Crownline 315 SCR 2009 or the Crownline 320 LS 2007?
For trailering, the Crownline 315 SCR 2009 has the edge at 11 lbs dry weight versus 95 lbs for the Crownline 320 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.
Which boat can handle a bigger outboard?
The Crownline 315 SCR 2009 is rated to a maximum of 750 hp, giving it the larger power ceiling. The Crownline 320 LS 2007 tops out at 640 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 315 SCR 2009 is Coast Guard rated for 9 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.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Crownline 315 SCR 2009 and Crownline 320 LS 2007 share an 116 in. (2.95 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.
How do the fuel tanks compare on the Crownline 315 SCR 2009 and Crownline 320 LS 2007?
Both boats carry similar fuel loads — 139 gallons and 139 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Crownline 315 SCR 2009 and Crownline 320 LS 2007 from the same manufacturer?
Yes — both the Crownline 315 SCR 2009 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.
