Sea Ray 520 Sedan Bridge 2012 vs Sea Ray Sundancer 500 1996: Same Brand, Different Boat

The Sea Ray 520 Sedan Bridge 2012 vs Sea Ray Sundancer 500 1996 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.

On paper these two are close siblings in the size department - Sea Ray 520 Sedan Bridge 2012 at 52,3 ft versus Sea Ray Sundancer 500 1996 at 50,0 ft. Weight tells a clearer story for trailering families: the Sea Ray 520 Sedan Bridge 2012 tips the scales at 42 000 lbs - 7 500 lbs more than the Sea Ray Sundancer 500 1996 at 34 500 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 2012 has a 29-hp advantage over the Sea Ray Sundancer 500 1996's 735-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 500 gal and 500 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: The Sea Ray 520 Sedan Bridge 2012 at 52,3 ft is the right call if deck space, comfort, and entertaining are top of your list. The Sea Ray Sundancer 500 1996 at 50,0 ft wins on trailering ease, likely lower purchase price, and simpler docking - a solid choice for a buyer who wants more boat for less money.

Sea Ray 520 Sedan Bridge 2012 vs Sea Ray Sundancer 500 1996 - Common Questions

Which is the larger boat - the Sea Ray 520 Sedan Bridge 2012 or the Sea Ray Sundancer 500 1996?
The Sea Ray 520 Sedan Bridge 2012 is the longer of the two at 52,3 feet overall. The Sea Ray Sundancer 500 1996 comes in at 50,0 feet, making it roughly 2,3 ft shorter - a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer - the Sea Ray 520 Sedan Bridge 2012 or the Sea Ray Sundancer 500 1996?
For trailering, the Sea Ray Sundancer 500 1996 has the edge at 34 500 lbs dry weight versus 42 000 lbs for the Sea Ray 520 Sedan Bridge 2012. 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 2012 is rated to a maximum of 764 hp, giving it the larger power ceiling. The Sea Ray Sundancer 500 1996 tops out at 735 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 Sundancer 500 1996 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 Sundancer 500 1996. 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 Sundancer 500 1996?
Both boats carry similar fuel loads - 500 gallons and 500 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Sea Ray 520 Sedan Bridge 2012 and Sea Ray Sundancer 500 1996 from the same manufacturer?
Yes - both the Sea Ray 520 Sedan Bridge 2012 and the Sea Ray Sundancer 500 1996 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.
