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.

Sea Ray 175 Sport 2008 vs Sea Ray 520 Sedan Bridge 2011 — Common Questions

Which is the larger boat — the Sea Ray 175 Sport 2008 or the Sea Ray 520 Sedan Bridge 2011?
The Sea Ray 520 Sedan Bridge 2011 is the longer of the two at 52,3 feet overall. The Sea Ray 175 Sport 2008 comes in at 17,0 feet, making it roughly 35,3 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sea Ray 175 Sport 2008 or the Sea Ray 520 Sedan Bridge 2011?
For trailering, the Sea Ray 175 Sport 2008 has the edge at 21 lbs dry weight versus 42 lbs for the Sea Ray 520 Sedan Bridge 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.
Which boat can handle a bigger outboard?
The Sea Ray 520 Sedan Bridge 2011 is rated to a maximum of 764 hp, giving it the larger power ceiling. The Sea Ray 175 Sport 2008 tops out at 135 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Sea Ray 175 Sport 2008 is Coast Guard rated for 7 passengers, while the Sea Ray 520 Sedan Bridge 2011 is certified for 15. 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 520 Sedan Bridge 2011 measures 183" wide, compared to 84" for the Sea Ray 175 Sport 2008. 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.
Which boat has the larger fuel tank — the Sea Ray 175 Sport 2008 or the Sea Ray 520 Sedan Bridge 2011?
The Sea Ray 175 Sport 2008 has the bigger tank at 21 gallons, versus 5 gallons on the Sea Ray 520 Sedan Bridge 2011. That 16-gallon difference translates to roughly 48–80 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Sea Ray 175 Sport 2008 and Sea Ray 520 Sedan Bridge 2011 from the same manufacturer?
Yes — both the Sea Ray 175 Sport 2008 and the Sea Ray 520 Sedan Bridge 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.
