Detailed Evaluation & Buyer Recommendation
Sea Ray 175 Sport 2008 vs Sea Ray 520 Sedan Bridge 2011 — Same Brand, Different Boat
The Sea Ray 175 Sport 2008 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 35,3 additional feet of deck space compared to the Sea Ray 175 Sport 2008 at 17,0 feet (2008). At 21 lbs and 42 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 764 hp, the Sea Ray 520 Sedan Bridge 2011 has a 629-hp advantage over the Sea Ray 175 Sport 2008's 135-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 175 Sport 2008 carries 21 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 175 Sport 2008 caps at 7. 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 175 Sport 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
