The Sea Ray 300 Sundeck 2010 vs Sea Ray Sundeck 260 2012 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 300 Sundeck 2010 measures 29,5 feet overall (2010), giving it roughly 3,1 additional feet of deck space compared to the Sea Ray Sundeck 260 2012 at 26,4 feet (2012). Weight tells a clearer story for trailering families: the Sea Ray 300 Sundeck 2010 tips the scales at 6 044 lbs — 844 lbs more than the Sea Ray Sundeck 260 2012 at 5 200 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 425 hp, the Sea Ray 300 Sundeck 2010 has a 125-hp advantage over the Sea Ray Sundeck 260 2012'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 300 Sundeck 2010 carries 93 gallons versus 65 gallons in the Sea Ray Sundeck 260 2012. 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.
