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

The Sea Ray 280 Sundancer 2010 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.

Both boats share a closely matched power ceiling — 375 hp for the Sea Ray 280 Sundancer 2010 and 380 hp for the Sea Ray Sedan Bridge 390 2010. 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. Fuel capacity breaks the other way: the Sea Ray 280 Sundancer 2010 carries 84 gallons versus 3 gallons in the Sea Ray Sedan Bridge 390 2010. 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 Bridge 390 2010 is rated for 11 passengers, while the Sea Ray 280 Sundancer 2010 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 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 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.
