Sea Ray 390 Sundancer 2005 vs Sea Ray Sundancer 610 2011 — Same Brand, Different Boat

The Sea Ray 390 Sundancer 2005 vs Sea Ray Sundancer 610 2011 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 Sea Ray Sundancer 610 2011 tops out at 1 050 hp. Engine specs for the Sea Ray 390 Sundancer 2005 aren't listed — confirm with a dealer before selecting an outboard.

For family outings this is probably the sharpest distinction between the two. The Sea Ray Sundancer 610 2011 is rated for 18 passengers, while the Sea Ray 390 Sundancer 2005 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray Sundancer 610 2011 could be the deciding factor.

Bottom line: Choose the Sea Ray Sundancer 610 2011 if your priority is putting more people on the water — it handles 18 passengers and at 61,6 ft it has the deck room to back that rating up comfortably.
