Sea Ray 270 Select EX 2005 vs Sea Ray 300 Sundeck 2012 — Same Brand, Different Boat
The Sea Ray 270 Select EX 2005 vs Sea Ray 300 Sundeck 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.
On paper these two are close siblings in the size department — Sea Ray 270 Select EX 2005 at 28,0 ft versus Sea Ray 300 Sundeck 2012 at 29,5 ft.

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 300 Sundeck 2012 tops out at 430 hp. Engine specs for the Sea Ray 270 Select EX 2005 aren't listed — confirm with a dealer before selecting an outboard.Both carry nearly identical fuel loads — 94 gal and 93 gal — so range won't be a tiebreaker here.
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.
Bottom line: The Sea Ray 270 Select EX 2005 and Sea Ray 300 Sundeck 2012 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
