Sea Ray 390 Sundancer 2010 vs Sea Ray Sundancer 610 2011 — Same Brand, Different Boat

The Sea Ray 390 Sundancer 2010 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 power gap is worth calling out. Rated to 1 050 hp, the Sea Ray Sundancer 610 2011 has a 625-hp advantage over the Sea Ray 390 Sundancer 2010's 425-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

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 2010 caps at 11. 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. The Sea Ray 390 Sundancer 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 11 that costs less to run day-to-day.

Sea Ray 390 Sundancer 2010 vs Sea Ray Sundancer 610 2011 — Common Questions

Which is the larger boat — the Sea Ray 390 Sundancer 2010 or the Sea Ray Sundancer 610 2011?
The Sea Ray Sundancer 610 2011 is the longer of the two at 61,6 feet overall. The Sea Ray 390 Sundancer 2010 comes in at 39,0 feet, making it roughly 22,6 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which boat can handle a bigger outboard?
The Sea Ray Sundancer 610 2011 is rated to a maximum of 1 050 hp, giving it the larger power ceiling. The Sea Ray 390 Sundancer 2010 tops out at 425 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 390 Sundancer 2010 is Coast Guard rated for 11 passengers, while the Sea Ray Sundancer 610 2011 is certified for 18. 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 Sundancer 610 2011 measures 203" wide, compared to 15" for the Sea Ray 390 Sundancer 2010. 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.
Are the Sea Ray 390 Sundancer 2010 and Sea Ray Sundancer 610 2011 from the same manufacturer?
Yes — both the Sea Ray 390 Sundancer 2010 and the Sea Ray Sundancer 610 2011 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.
