Sea Ray 520 Sedan Bridge 2012 vs Sea Ray Sedan Bridge 525 2005 — Same Brand, Different Boat

The Sea Ray 520 Sedan Bridge 2012 vs Sea Ray Sedan Bridge 525 2005 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.

The power gap is worth calling out. Rated to 764 hp, the Sea Ray 520 Sedan Bridge 2012 has a 66-hp advantage over the Sea Ray Sedan Bridge 525 2005's 698-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 5 gal and 5 gal — so range won't be a tiebreaker here.

Both boats are rated for 15 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: Performance buyers should lean toward the Sea Ray 520 Sedan Bridge 2012 and its 764-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Sea Ray Sedan Bridge 525 2005 with its 698-hp rating is the more economical daily driver.

Sea Ray 520 Sedan Bridge 2012 vs Sea Ray Sedan Bridge 525 2005 — Common Questions

Which is the larger boat — the Sea Ray 520 Sedan Bridge 2012 or the Sea Ray Sedan Bridge 525 2005?
The Sea Ray 520 Sedan Bridge 2012 is the longer of the two at 52,3 feet overall. The Sea Ray Sedan Bridge 525 2005 comes in at 52,0 feet, making it roughly 0,3 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which boat can handle a bigger outboard?
The Sea Ray 520 Sedan Bridge 2012 is rated to a maximum of 764 hp, giving it the larger power ceiling. The Sea Ray Sedan Bridge 525 2005 tops out at 698 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 520 Sedan Bridge 2012 is Coast Guard rated for 15 passengers, while the Sea Ray Sedan Bridge 525 2005 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 2012 measures 183" wide, compared to 180" for the Sea Ray Sedan Bridge 525 2005. 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 520 Sedan Bridge 2012 and Sea Ray Sedan Bridge 525 2005?
Both boats carry similar fuel loads — 5 gallons and 5 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.

Yes — both the Sea Ray 520 Sedan Bridge 2012 and the Sea Ray Sedan Bridge 525 2005 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.
