Sea Ray 450 Sundancer 2011 vs Sea Ray Sedan Bridge 400 2001 — Same Brand, Different Boat

The Sea Ray 450 Sundancer 2011 vs Sea Ray Sedan Bridge 400 2001 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 450 Sundancer 2011 measures 45,4 feet overall (2011), giving it roughly 3,4 additional feet of deck space compared to the Sea Ray Sedan Bridge 400 2001 at 42,0 feet (2001). Weight tells a clearer story for trailering families: the Sea Ray 450 Sundancer 2011 tips the scales at 27 205 lbs — 5 205 lbs more than the Sea Ray Sedan Bridge 400 2001 at 22 000 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 480 hp, the Sea Ray 450 Sundancer 2011 has a 100-hp advantage over the Sea Ray Sedan Bridge 400 2001's 380-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 450 Sundancer 2011 carries 292 gallons versus 35 gallons in the Sea Ray Sedan Bridge 400 2001. 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 450 Sundancer 2011 is rated for 13 passengers, while the Sea Ray Sedan Bridge 400 2001 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray 450 Sundancer 2011 could be the deciding factor.

Bottom line: Choose the Sea Ray 450 Sundancer 2011 if your priority is putting more people on the water — it handles 13 passengers and at 45,4 ft it has the deck room to back that rating up comfortably. The Sea Ray Sedan Bridge 400 2001 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 12 that costs less to run day-to-day.

Sea Ray 450 Sundancer 2011 vs Sea Ray Sedan Bridge 400 2001 — Common Questions

Which is the larger boat — the Sea Ray 450 Sundancer 2011 or the Sea Ray Sedan Bridge 400 2001?
The Sea Ray 450 Sundancer 2011 is the longer of the two at 45,4 feet overall. The Sea Ray Sedan Bridge 400 2001 comes in at 42,0 feet, making it roughly 3,4 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sea Ray 450 Sundancer 2011 or the Sea Ray Sedan Bridge 400 2001?
For trailering, the Sea Ray Sedan Bridge 400 2001 has the edge at 22 000 lbs dry weight versus 27 205 lbs for the Sea Ray 450 Sundancer 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 450 Sundancer 2011 is rated to a maximum of 480 hp, giving it the larger power ceiling. The Sea Ray Sedan Bridge 400 2001 tops out at 380 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 450 Sundancer 2011 is Coast Guard rated for 13 passengers, while the Sea Ray Sedan Bridge 400 2001 is certified for 12. 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 Bridge 400 2001 measures 172" wide, compared to 158" for the Sea Ray 450 Sundancer 2011. 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 450 Sundancer 2011 or the Sea Ray Sedan Bridge 400 2001?
The Sea Ray 450 Sundancer 2011 has the bigger tank at 292 gallons, versus 35 gallons on the Sea Ray Sedan Bridge 400 2001. That 257-gallon difference translates to roughly 771–1285 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Sea Ray 450 Sundancer 2011 and Sea Ray Sedan Bridge 400 2001 from the same manufacturer?
Yes — both the Sea Ray 450 Sundancer 2011 and the Sea Ray Sedan Bridge 400 2001 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.
