Crownline 270 CR 2007 vs Crownline 305 SS 2011 — Same Brand, Different Boat

The Crownline 270 CR 2007 vs Crownline 305 SS 2011 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 270 CR 2007 at 28,0 ft versus Crownline 305 SS 2011 at 30,5 ft. At 76 lbs and 89 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 600 hp, the Crownline 305 SS 2011 has a 175-hp advantage over the Crownline 270 CR 2007's 425-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 305 SS 2011 carries 84 gallons versus 75 gallons in the Crownline 270 CR 2007. 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 305 SS 2011 is rated for 9 passengers, while the Crownline 270 CR 2007 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crownline 305 SS 2011 could be the deciding factor.

Bottom line: Choose the Crownline 305 SS 2011 if your priority is putting more people on the water — it handles 9 passengers and at 30,5 ft it has the deck room to back that rating up comfortably. The Crownline 270 CR 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.

Crownline 270 CR 2007 vs Crownline 305 SS 2011 — Common Questions

Which is the larger boat — the Crownline 270 CR 2007 or the Crownline 305 SS 2011?
The Crownline 305 SS 2011 is the longer of the two at 30,5 feet overall. The Crownline 270 CR 2007 comes in at 28,0 feet, making it roughly 2,5 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Crownline 270 CR 2007 or the Crownline 305 SS 2011?
For trailering, the Crownline 270 CR 2007 has the edge at 76 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 305 SS 2011 is rated to a maximum of 600 hp, giving it the larger power ceiling. The Crownline 270 CR 2007 tops out at 425 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 270 CR 2007 is Coast Guard rated for 8 passengers, while the Crownline 305 SS 2011 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 305 SS 2011 measures 112" wide, compared to 102" for the Crownline 270 CR 2007. 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 270 CR 2007 or the Crownline 305 SS 2011?
The Crownline 305 SS 2011 has the bigger tank at 84 gallons, versus 75 gallons on the Crownline 270 CR 2007. That 9-gallon difference translates to roughly 27–45 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Crownline 270 CR 2007 and Crownline 305 SS 2011 from the same manufacturer?
Yes — both the Crownline 270 CR 2007 and the Crownline 305 SS 2011 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.
