Sea Ray 185 Sport 2006 vs Sea Ray 55 Sundancer 2007 — Same Brand, Different Boat

The Sea Ray 185 Sport 2006 vs Sea Ray 55 Sundancer 2007 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.

Size is the most obvious dividing line here. The Sea Ray 185 Sport 2006 measures 19,0 feet overall (2006), giving it roughly 13,0 additional feet of deck space compared to the Sea Ray 55 Sundancer 2007 at 6,0 feet (2007). At 24 lbs and 53 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 861 hp, the Sea Ray 55 Sundancer 2007 has a 671-hp advantage over the Sea Ray 185 Sport 2006's 190-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 2007 carries 825 gallons versus 26 gallons in the Sea Ray 185 Sport 2006. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

The Sea Ray 185 Sport 2006 is rated for up to 8 people. Passenger data for the Sea Ray 55 Sundancer 2007 wasn't available.

Bottom line: The Sea Ray 185 Sport 2006 at 19,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Sea Ray 55 Sundancer 2007 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 185 Sport 2006 vs Sea Ray 55 Sundancer 2007 — Common Questions

Which is the larger boat — the Sea Ray 185 Sport 2006 or the Sea Ray 55 Sundancer 2007?
The Sea Ray 185 Sport 2006 is the longer of the two at 19,0 feet overall. The Sea Ray 55 Sundancer 2007 comes in at 6,0 feet, making it roughly 13,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sea Ray 185 Sport 2006 or the Sea Ray 55 Sundancer 2007?
For trailering, the Sea Ray 185 Sport 2006 has the edge at 24 lbs dry weight versus 53 lbs for the Sea Ray 55 Sundancer 2007. 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 2007 is rated to a maximum of 861 hp, giving it the larger power ceiling. The Sea Ray 185 Sport 2006 tops out at 190 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 passengers can the Sea Ray 185 Sport 2006 carry?
The Sea Ray 185 Sport 2006 has an official capacity rating of 8 people. Capacity data wasn't available for the other model in this comparison — verify directly with the dealer.
Which boat is wider, and does it affect trailering?
The Sea Ray 55 Sundancer 2007 measures 191" wide, compared to 87" for the Sea Ray 185 Sport 2006. 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 185 Sport 2006 or the Sea Ray 55 Sundancer 2007?
The Sea Ray 55 Sundancer 2007 has the bigger tank at 825 gallons, versus 26 gallons on the Sea Ray 185 Sport 2006. That 799-gallon difference translates to roughly 2397–3995 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Yes — both the Sea Ray 185 Sport 2006 and the Sea Ray 55 Sundancer 2007 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.
