Sea Ray 260 Sundeck 2008 vs Sea Ray 390 Motor Yacht 2005 — Same Brand, Different Boat

The Sea Ray 260 Sundeck 2008 vs Sea Ray 390 Motor Yacht 2005 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 390 Motor Yacht 2005 measures 41,0 feet overall (2005), giving it roughly 15,0 additional feet of deck space compared to the Sea Ray 260 Sundeck 2008 at 26,0 feet (2008). Weight tells a clearer story for trailering families: the Sea Ray 260 Sundeck 2008 tips the scales at 5 074 lbs — 4 809 lbs more than the Sea Ray 390 Motor Yacht 2005 at 265 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 260 Sundeck 2008 carries a rated maximum of 375 hp. Engine data for the Sea Ray 390 Motor Yacht 2005 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Sea Ray 260 Sundeck 2008 carries 65 gallons versus 3 gallons in the Sea Ray 390 Motor Yacht 2005. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 12 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: The Sea Ray 390 Motor Yacht 2005 at 41,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Sea Ray 260 Sundeck 2008 at 26,0 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.
