Sea Ray 300 SLX® 2011 vs Sea Ray Sundancer 270 2009 — Same Brand, Different Boat

The Sea Ray 300 SLX® 2011 vs Sea Ray Sundancer 270 2009 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 — Sea Ray 300 SLX® 2011 at 29,5 ft versus Sea Ray Sundancer 270 2009 at 28,0 ft. Weight tells a clearer story for trailering families: the Sea Ray Sundancer 270 2009 tips the scales at 8 211 lbs — 8 134 lbs less than the Sea Ray 300 SLX® 2011 at 77 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 380 hp, the Sea Ray 300 SLX® 2011 has a 60-hp advantage over the Sea Ray Sundancer 270 2009's 320-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Sea Ray Sundancer 270 2009 carries 84 gallons versus 13 gallons in the Sea Ray 300 SLX® 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 8 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 Sea Ray 300 SLX® 2011 and its 380-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Sea Ray Sundancer 270 2009 with its 320-hp rating is the more economical daily driver.

Sea Ray 300 SLX® 2011 vs Sea Ray Sundancer 270 2009 — Common Questions

Which is the larger boat — the Sea Ray 300 SLX® 2011 or the Sea Ray Sundancer 270 2009?
The Sea Ray 300 SLX® 2011 is the longer of the two at 29,5 feet overall. The Sea Ray Sundancer 270 2009 comes in at 28,0 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 Sea Ray 300 SLX® 2011 or the Sea Ray Sundancer 270 2009?
For trailering, the Sea Ray 300 SLX® 2011 has the edge at 77 lbs dry weight versus 8 211 lbs for the Sea Ray Sundancer 270 2009. 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 Sea Ray 300 SLX® 2011 is rated to a maximum of 380 hp, giving it the larger power ceiling. The Sea Ray Sundancer 270 2009 tops out at 320 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 Sea Ray 300 SLX® 2011 is Coast Guard rated for 8 passengers, while the Sea Ray Sundancer 270 2009 is certified for 8. 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 Sea Ray 300 SLX® 2011 measures 116" wide, compared to 97" for the Sea Ray Sundancer 270 2009. 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 Sea Ray 300 SLX® 2011 or the Sea Ray Sundancer 270 2009?
The Sea Ray Sundancer 270 2009 has the bigger tank at 84 gallons, versus 13 gallons on the Sea Ray 300 SLX® 2011. That 71-gallon difference translates to roughly 213–355 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Sea Ray 300 SLX® 2011 and Sea Ray Sundancer 270 2009 from the same manufacturer?
Yes — both the Sea Ray 300 SLX® 2011 and the Sea Ray Sundancer 270 2009 are built by Sea Ray. 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.
