Sea Ray 230 Sundancer 2009 vs Sea Ray 520 Sedan Bridge 2011 — Same Brand, Different Boat

Matching a modified vee Sea Ray 230 Sundancer 2009 against a semi displacement Sea Ray 520 Sedan Bridge 2011 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 2011 measures 52,3 feet overall (2011), giving it roughly 27,8 additional feet of deck space compared to the Sea Ray 230 Sundancer 2009 at 24,5 feet (2009). Weight tells a clearer story for trailering families: the Sea Ray 230 Sundancer 2009 tips the scales at 5 593 lbs — 5 551 lbs more than the Sea Ray 520 Sedan Bridge 2011 at 42 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 2011 has a 464-hp advantage over the Sea Ray 230 Sundancer 2009's 300-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 230 Sundancer 2009 carries 75 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 230 Sundancer 2009 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 230 Sundancer 2009 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 230 Sundancer 2009 vs Sea Ray 520 Sedan Bridge 2011 — Common Questions

Which is the larger boat — the Sea Ray 230 Sundancer 2009 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 230 Sundancer 2009 comes in at 24,5 feet, making it roughly 27,8 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sea Ray 230 Sundancer 2009 or the Sea Ray 520 Sedan Bridge 2011?
For trailering, the Sea Ray 520 Sedan Bridge 2011 has the edge at 42 lbs dry weight versus 5 593 lbs for the Sea Ray 230 Sundancer 2009. 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 230 Sundancer 2009 tops out at 300 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 230 Sundancer 2009 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 102" for the Sea Ray 230 Sundancer 2009. 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 230 Sundancer 2009 or the Sea Ray 520 Sedan Bridge 2011?
The Sea Ray 230 Sundancer 2009 has the bigger tank at 75 gallons, versus 5 gallons on the Sea Ray 520 Sedan Bridge 2011. That 70-gallon difference translates to roughly 210–350 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Sea Ray 230 Sundancer 2009 and Sea Ray 520 Sedan Bridge 2011 from the same manufacturer?
Yes — both the Sea Ray 230 Sundancer 2009 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.
