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.

Sea Ray 270 Select EX 2007 vs Sea Ray 300 Sundeck 2011 — Common Questions

Which is the larger boat — the Sea Ray 270 Select EX 2007 or the Sea Ray 300 Sundeck 2011?
The Sea Ray 300 Sundeck 2011 is the longer of the two at 29,5 feet overall. The Sea Ray 270 Select EX 2007 comes in at 28,0 feet, making it roughly 1,5 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sea Ray 270 Select EX 2007 or the Sea Ray 300 Sundeck 2011?
For trailering, the Sea Ray 270 Select EX 2007 has the edge at 5 555 lbs dry weight versus 6 044 lbs for the Sea Ray 300 Sundeck 2011. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
How many people can each boat hold?
The Sea Ray 270 Select EX 2007 is Coast Guard rated for 8 passengers, while the Sea Ray 300 Sundeck 2011 is certified for 8. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Sea Ray 300 Sundeck 2011 measures 109" wide, compared to 108" for the Sea Ray 270 Select EX 2007. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
How do the fuel tanks compare on the Sea Ray 270 Select EX 2007 and Sea Ray 300 Sundeck 2011?
Both boats carry similar fuel loads — 94 gallons and 93 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Sea Ray 270 Select EX 2007 and Sea Ray 300 Sundeck 2011 from the same manufacturer?
Yes — both the Sea Ray 270 Select EX 2007 and the Sea Ray 300 Sundeck 2011 are built by Sea Ray. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
