Crownline 305 SS 2011 vs Crownline 315 SCR 2008 — Same Brand, Different Boat

The Crownline 305 SS 2011 vs Crownline 315 SCR 2008 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 305 SS 2011 at 30,5 ft versus Crownline 315 SCR 2008 at 32,0 ft. At 89 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 315 SCR 2008 has a 150-hp advantage over the Crownline 305 SS 2011's 600-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 315 SCR 2008 carries 139 gallons versus 84 gallons in the Crownline 305 SS 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

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 2008 and its 750-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Crownline 305 SS 2011 with its 600-hp rating is the more economical daily driver.

Crownline 305 SS 2011 vs Crownline 315 SCR 2008 — Common Questions

Which is the larger boat — the Crownline 305 SS 2011 or the Crownline 315 SCR 2008?
The Crownline 315 SCR 2008 is the longer of the two at 32,0 feet overall. The Crownline 305 SS 2011 comes in at 30,5 feet, making it roughly 1,5 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Crownline 305 SS 2011 or the Crownline 315 SCR 2008?
For trailering, the Crownline 315 SCR 2008 has the edge at 11 lbs dry weight versus 89 lbs for the Crownline 305 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 315 SCR 2008 is rated to a maximum of 750 hp, giving it the larger power ceiling. The Crownline 305 SS 2011 tops out at 600 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 305 SS 2011 is Coast Guard rated for 9 passengers, while the Crownline 315 SCR 2008 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 315 SCR 2008 measures 116" wide, compared to 112" for the Crownline 305 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 305 SS 2011 or the Crownline 315 SCR 2008?
The Crownline 315 SCR 2008 has the bigger tank at 139 gallons, versus 84 gallons on the Crownline 305 SS 2011. That 55-gallon difference translates to roughly 165–275 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Crownline 305 SS 2011 and Crownline 315 SCR 2008 from the same manufacturer?
Yes — both the Crownline 305 SS 2011 and the Crownline 315 SCR 2008 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.
