Sea Ray 300 Select EX 2010 vs Sea Ray 55 Sundancer 2009 — Same Brand, Different Boat

Matching a modified vee Sea Ray 300 Select EX 2010 against a semi displacement Sea Ray 55 Sundancer 2009 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.

Size is the most obvious dividing line here. The Sea Ray 300 Select EX 2010 measures 29,5 feet overall (2010), giving it roughly 23,5 additional feet of deck space compared to the Sea Ray 55 Sundancer 2009 at 6,0 feet (2009). Weight tells a clearer story for trailering families: the Sea Ray 55 Sundancer 2009 tips the scales at 535 lbs — 458 lbs less than the Sea Ray 300 Select EX 2010 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 1 051 hp, the Sea Ray 55 Sundancer 2009 has a 751-hp advantage over the Sea Ray 300 Select EX 2010's 300-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 55 Sundancer 2009 carries 825 gallons versus 13 gallons in the Sea Ray 300 Select EX 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

The Sea Ray 300 Select EX 2010 is rated for up to 8 people. Passenger data for the Sea Ray 55 Sundancer 2009 wasn't available.

Bottom line: The Sea Ray 300 Select EX 2010 at 29,5 ft is the right call if deck space, comfort, and entertaining are top of your list. The Sea Ray 55 Sundancer 2009 at 6,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.

Sea Ray 300 Select EX 2010 vs Sea Ray 55 Sundancer 2009 — Common Questions

Which is the larger boat — the Sea Ray 300 Select EX 2010 or the Sea Ray 55 Sundancer 2009?
The Sea Ray 300 Select EX 2010 is the longer of the two at 29,5 feet overall. The Sea Ray 55 Sundancer 2009 comes in at 6,0 feet, making it roughly 23,5 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sea Ray 300 Select EX 2010 or the Sea Ray 55 Sundancer 2009?
For trailering, the Sea Ray 300 Select EX 2010 has the edge at 77 lbs dry weight versus 535 lbs for the Sea Ray 55 Sundancer 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 55 Sundancer 2009 is rated to a maximum of 1 051 hp, giving it the larger power ceiling. The Sea Ray 300 Select EX 2010 tops out at 300 hp.
