The Sea Ray 300 Sundeck 2011 vs Sea Ray SDX 270 Outboard 2018 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.

On paper these two are close siblings in the size department — Sea Ray 300 Sundeck 2011 at 29,5 ft versus Sea Ray SDX 270 Outboard 2018 at 29,2 ft. Weight tells a clearer story for trailering families: the Sea Ray 300 Sundeck 2011 tips the scales at 6 044 lbs — 384 lbs more than the Sea Ray SDX 270 Outboard 2018 at 5 660 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 430 hp, the Sea Ray 300 Sundeck 2011 has a 180-hp advantage over the Sea Ray SDX 270 Outboard 2018's 250-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 2011 carries 93 gallons versus 65 gallons in the Sea Ray SDX 270 Outboard 2018. 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.
