Detailed Evaluation & Buyer Recommendation

Sea Ray 240 Select 2005 vs Sea Ray 580 Sundancer 2010 — Same Brand, Different Boat

The Sea Ray 240 Select 2005 vs Sea Ray 580 Sundancer 2010 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 240 Select 2005 measures 25,0 feet overall (2005), giving it roughly 19,0 additional feet of deck space compared to the Sea Ray 580 Sundancer 2010 at 6,0 feet (2010). Weight tells a clearer story for trailering families: the Sea Ray 580 Sundancer 2010 tips the scales at 535 lbs — 490 lbs less than the Sea Ray 240 Select 2005 at 45 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 Sea Ray 580 Sundancer 2010 tops out at 1 051 hp. Engine specs for the Sea Ray 240 Select 2005 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Sea Ray 580 Sundancer 2010 carries 825 gallons versus 57 gallons in the Sea Ray 240 Select 2005. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

The Sea Ray 240 Select 2005 is rated for up to 1 people. Passenger data for the Sea Ray 580 Sundancer 2010 wasn't available.

Bottom line: The Sea Ray 240 Select 2005 at 25,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Sea Ray 580 Sundancer 2010 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.
