Sea Ray 450 Sedan Bridge 2011 vs Sea Ray Sundancer 470 2013 — Same Brand, Different Boat

The Sea Ray 450 Sedan Bridge 2011 vs Sea Ray Sundancer 470 2013 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 450 Sedan Bridge 2011 at 45,4 ft versus Sea Ray Sundancer 470 2013 at 47,3 ft. Weight tells a clearer story for trailering families: the Sea Ray Sundancer 470 2013 tips the scales at 28 500 lbs — 28 215 lbs less than the Sea Ray 450 Sedan Bridge 2011 at 285 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.

Both boats share a closely matched power ceiling — 478 hp for the Sea Ray 450 Sedan Bridge 2011 and 480 hp for the Sea Ray Sundancer 470 2013. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads — 35 gal and 35 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Sea Ray Sundancer 470 2013 is rated for 14 passengers, while the Sea Ray 450 Sedan Bridge 2011 caps at 13. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray Sundancer 470 2013 could be the deciding factor.

Bottom line: Choose the Sea Ray Sundancer 470 2013 if your priority is putting more people on the water — it handles 14 passengers and at 47,3 ft it has the deck room to back that rating up comfortably. The Sea Ray 450 Sedan Bridge 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 13 that costs less to run day-to-day.

Sea Ray 450 Sedan Bridge 2011 vs Sea Ray Sundancer 470 2013 — Common Questions

Which is the larger boat — the Sea Ray 450 Sedan Bridge 2011 or the Sea Ray Sundancer 470 2013?
The Sea Ray Sundancer 470 2013 is the longer of the two at 47,3 feet overall. The Sea Ray 450 Sedan Bridge 2011 comes in at 45,4 feet, making it roughly 1,9 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sea Ray 450 Sedan Bridge 2011 or the Sea Ray Sundancer 470 2013?
For trailering, the Sea Ray 450 Sedan Bridge 2011 has the edge at 285 lbs dry weight versus 28 500 lbs for the Sea Ray Sundancer 470 2013. 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.
How many people can each boat hold?
The Sea Ray 450 Sedan Bridge 2011 is Coast Guard rated for 13 passengers, while the Sea Ray Sundancer 470 2013 is certified for 14. 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 450 Sedan Bridge 2011 measures 171" wide, compared to 169" for the Sea Ray Sundancer 470 2013. 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 450 Sedan Bridge 2011 and Sea Ray Sundancer 470 2013?
Both boats carry similar fuel loads — 35 gallons and 35 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 450 Sedan Bridge 2011 and Sea Ray Sundancer 470 2013 from the same manufacturer?
Yes — both the Sea Ray 450 Sedan Bridge 2011 and the Sea Ray Sundancer 470 2013 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.
