The Sea Ray 390 Sedan Bridge 2011 tops out at 375 hp. Engine specs for the Sea Ray 280 Sundancer 2005 aren't listed — confirm with a dealer before selecting an outboard.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 390 Sedan Bridge 2011 is rated for 12 passengers, while the Sea Ray 280 Sundancer 2005 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 390 Sedan Bridge 2011 could be the deciding factor.
Bottom line: Choose the Sea Ray 390 Sedan Bridge 2011 if your priority is putting more people on the water — it handles 12 passengers and at 40,8 ft it has the deck room to back that rating up comfortably. The Sea Ray 280 Sundancer 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.
