Detailed Evaluation & Buyer Recommendation
Sea Ray 270 Select EX 2007 vs Sea Ray 520 Sedan Bridge 2011 — Same Brand, Different Boat
The Sea Ray 270 Select EX 2007 vs Sea Ray 520 Sedan Bridge 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.
Size is the most obvious dividing line here. The Sea Ray 520 Sedan Bridge 2011 measures 52,3 feet overall (2011), giving it roughly 24,3 additional feet of deck space compared to the Sea Ray 270 Select EX 2007 at 28,0 feet (2007). Weight tells a clearer story for trailering families: the Sea Ray 270 Select EX 2007 tips the scales at 5 555 lbs — 5 513 lbs more than the Sea Ray 520 Sedan Bridge 2011 at 42 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 764 hp, the Sea Ray 520 Sedan Bridge 2011 has a 339-hp advantage over the Sea Ray 270 Select EX 2007's 425-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 270 Select EX 2007 carries 94 gallons versus 5 gallons in the Sea Ray 520 Sedan Bridge 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Sea Ray 520 Sedan Bridge 2011 is rated for 15 passengers, while the Sea Ray 270 Select EX 2007 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray 520 Sedan Bridge 2011 could be the deciding factor.
Bottom line: Choose the Sea Ray 520 Sedan Bridge 2011 if your priority is putting more people on the water — it handles 15 passengers and at 52,3 ft it has the deck room to back that rating up comfortably. The Sea Ray 270 Select EX 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
