Detailed Evaluation & Buyer Recommendation
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.
