Detailed Evaluation & Buyer Recommendation
Sea Ray 175 Sport 2011 vs Sea Ray 520 Sedan Bridge 2013 — Same Brand, Different Boat
Matching a modified vee Sea Ray 175 Sport 2011 against a semi displacement Sea Ray 520 Sedan Bridge 2013 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
Size is the most obvious dividing line here. The Sea Ray 520 Sedan Bridge 2013 measures 52,3 feet overall (2013), giving it roughly 34,8 additional feet of deck space compared to the Sea Ray 175 Sport 2011 at 17,5 feet (2011). At 21 lbs and 51 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 641 hp, the Sea Ray 520 Sedan Bridge 2013 has a 506-hp advantage over the Sea Ray 175 Sport 2011'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 2011 carries 21 gallons versus 5 gallons in the Sea Ray 520 Sedan Bridge 2013. 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 2013 is rated for 15 passengers, while the Sea Ray 175 Sport 2011 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 2013 could be the deciding factor.
Bottom line: Choose the Sea Ray 520 Sedan Bridge 2013 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 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
