Sea Ray Sedan 550 1996 vs Sea Ray Sundancer 320 2022 — Same Brand, Different Boat

The Sea Ray Sedan 550 1996 vs Sea Ray Sundancer 320 2022 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 Sedan 550 1996 measures 56,1 feet overall (1996), giving it roughly 20,7 additional feet of deck space compared to the Sea Ray Sundancer 320 2022 at 35,4 feet (2022). Weight tells a clearer story for trailering families: the Sea Ray Sedan 550 1996 tips the scales at 45 700 lbs — 31 700 lbs more than the Sea Ray Sundancer 320 2022 at 14 000 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 800 hp, the Sea Ray Sedan 550 1996 has a 500-hp advantage over the Sea Ray Sundancer 320 2022'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 Sundancer 320 2022 carries 158 gallons versus 7 gallons in the Sea Ray Sedan 550 1996. 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 Sedan 550 1996 is rated for 17 passengers, while the Sea Ray Sundancer 320 2022 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray Sedan 550 1996 could be the deciding factor.

Bottom line: Choose the Sea Ray Sedan 550 1996 if your priority is putting more people on the water — it handles 17 passengers and at 56,1 ft it has the deck room to back that rating up comfortably. The Sea Ray Sundancer 320 2022 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.

Sea Ray Sedan 550 1996 vs Sea Ray Sundancer 320 2022 — Common Questions

Which is the larger boat — the Sea Ray Sedan 550 1996 or the Sea Ray Sundancer 320 2022?
The Sea Ray Sedan 550 1996 is the longer of the two at 56,1 feet overall. The Sea Ray Sundancer 320 2022 comes in at 35,4 feet, making it roughly 20,7 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sea Ray Sedan 550 1996 or the Sea Ray Sundancer 320 2022?
For trailering, the Sea Ray Sundancer 320 2022 has the edge at 14 000 lbs dry weight versus 45 700 lbs for the Sea Ray Sedan 550 1996. 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 Sedan 550 1996 is rated to a maximum of 800 hp, giving it the larger power ceiling. The Sea Ray Sundancer 320 2022 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 Sedan 550 1996 is Coast Guard rated for 17 passengers, while the Sea Ray Sundancer 320 2022 is certified for 10. 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 Sedan 550 1996 measures 180" wide, compared to 128" for the Sea Ray Sundancer 320 2022. 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 Sedan 550 1996 or the Sea Ray Sundancer 320 2022?
The Sea Ray Sundancer 320 2022 has the bigger tank at 158 gallons, versus 7 gallons on the Sea Ray Sedan 550 1996. That 151-gallon difference translates to roughly 453–755 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Sea Ray Sedan 550 1996 and Sea Ray Sundancer 320 2022 from the same manufacturer?
Yes — both the Sea Ray Sedan 550 1996 and the Sea Ray Sundancer 320 2022 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.
