Detailed Evaluation & Buyer Recommendation
Sea Ray 270 Select EX 2007 vs Sea Ray 300 Sundeck 2011 — Same Brand, Different Boat
The Sea Ray 270 Select EX 2007 vs Sea Ray 300 Sundeck 2011 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 2007 at 28,0 ft versus Sea Ray 300 Sundeck 2011 at 29,5 ft. Weight tells a clearer story for trailering families: the Sea Ray 300 Sundeck 2011 tips the scales at 6 044 lbs — 489 lbs less than the Sea Ray 270 Select EX 2007 at 5 555 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.
Both boats share a closely matched power ceiling — 425 hp for the Sea Ray 270 Select EX 2007 and 430 hp for the Sea Ray 300 Sundeck 2011. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. 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 2007 and Sea Ray 300 Sundeck 2011 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.
