Sea Ray 280 Sundancer 2006 vs Sea Ray Sedan Bridge 390 2010 — Same Brand, Different Boat

The Sea Ray 280 Sundancer 2006 vs Sea Ray Sedan Bridge 390 2010 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.

The power gap is worth calling out. Rated to 380 hp, the Sea Ray Sedan Bridge 390 2010 has a 83-hp advantage over the Sea Ray 280 Sundancer 2006's 297-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 1 gal and 3 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Sea Ray Sedan Bridge 390 2010 is rated for 11 passengers, while the Sea Ray 280 Sundancer 2006 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray Sedan Bridge 390 2010 could be the deciding factor.

Bottom line: Choose the Sea Ray Sedan Bridge 390 2010 if your priority is putting more people on the water — it handles 11 passengers and at 39,0 ft it has the deck room to back that rating up comfortably. The Sea Ray 280 Sundancer 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.

Sea Ray 280 Sundancer 2006 vs Sea Ray Sedan Bridge 390 2010 — Common Questions

The Sea Ray Sedan Bridge 390 2010 is the longer of the two at 39,0 feet overall. The Sea Ray 280 Sundancer 2006 comes in at 31,0 feet, making it roughly 8,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which boat can handle a bigger outboard?
The Sea Ray Sedan Bridge 390 2010 is rated to a maximum of 380 hp, giving it the larger power ceiling. The Sea Ray 280 Sundancer 2006 tops out at 297 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 280 Sundancer 2006 is Coast Guard rated for 9 passengers, while the Sea Ray Sedan Bridge 390 2010 is certified for 11. 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 390 2010 measures 156" wide, compared to 113" for the Sea Ray 280 Sundancer 2006. 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 280 Sundancer 2006 and Sea Ray Sedan Bridge 390 2010?
Both boats carry similar fuel loads — 1 gallons and 3 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 280 Sundancer 2006 and Sea Ray Sedan Bridge 390 2010 from the same manufacturer?
Yes — both the Sea Ray 280 Sundancer 2006 and the Sea Ray Sedan Bridge 390 2010 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.
