Sea Ray 280 Sundancer 2011 vs Sea Ray 300 Select EX 2008 — Same Brand, Different Boat

Matching a deep vee Sea Ray 280 Sundancer 2011 against a modified vee Sea Ray 300 Select EX 2008 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

The power gap is worth calling out. Rated to 380 hp, the Sea Ray 280 Sundancer 2011 has a 60-hp advantage over the Sea Ray 300 Select EX 2008'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 280 Sundancer 2011 carries 84 gallons versus 13 gallons in the Sea Ray 300 Select EX 2008. 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 280 Sundancer 2011 and its 380-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Sea Ray 300 Select EX 2008 with its 320-hp rating is the more economical daily driver.

Sea Ray 280 Sundancer 2011 vs Sea Ray 300 Select EX 2008 — Common Questions

Which is the larger boat — the Sea Ray 280 Sundancer 2011 or the Sea Ray 300 Select EX 2008?
The Sea Ray 300 Select EX 2008 is the longer of the two at 29,0 feet overall. The Sea Ray 280 Sundancer 2011 comes in at 28,7 feet, making it roughly 0,3 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which boat can handle a bigger outboard?
The Sea Ray 280 Sundancer 2011 is rated to a maximum of 380 hp, giving it the larger power ceiling. The Sea Ray 300 Select EX 2008 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 280 Sundancer 2011 is Coast Guard rated for 8 passengers, while the Sea Ray 300 Select EX 2008 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 Select EX 2008 measures 116" wide, compared to 106" for the Sea Ray 280 Sundancer 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 Sea Ray 280 Sundancer 2011 or the Sea Ray 300 Select EX 2008?
The Sea Ray 280 Sundancer 2011 has the bigger tank at 84 gallons, versus 13 gallons on the Sea Ray 300 Select EX 2008. 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 280 Sundancer 2011 and Sea Ray 300 Select EX 2008 from the same manufacturer?
Yes — both the Sea Ray 280 Sundancer 2011 and the Sea Ray 300 Select EX 2008 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.
