Sea Ray 390 Sundancer 2010 vs Sea Ray 390 Sundancer 2011 — A Close Look at Two Semi Displacements

When two boats share the same hull type — in this case both the Sea Ray 390 Sundancer 2010 and the Sea Ray 390 Sundancer 2011 are semi displacement designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

On paper these two are close siblings in the size department — Sea Ray 390 Sundancer 2010 at 39,0 ft versus Sea Ray 390 Sundancer 2011 at 39,0 ft. At 246 lbs and 246 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

Both boats share a closely matched power ceiling — 425 hp for the Sea Ray 390 Sundancer 2010 and 425 hp for the Sea Ray 390 Sundancer 2011. 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. Both carry nearly identical fuel loads — 25 gal and 25 gal — so range won't be a tiebreaker here.

Both boats are rated for 11 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: The Sea Ray 390 Sundancer 2010 and Sea Ray 390 Sundancer 2011 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.

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

Which is the larger boat — the Sea Ray 390 Sundancer 2010 or the Sea Ray 390 Sundancer 2011?
The Sea Ray 390 Sundancer 2011 is the longer of the two at 39,0 feet overall. The Sea Ray 390 Sundancer 2010 comes in at 39,0 feet, making it roughly 0,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sea Ray 390 Sundancer 2010 or the Sea Ray 390 Sundancer 2011?
For trailering, the Sea Ray 390 Sundancer 2011 has the edge at 246 lbs dry weight versus 246 lbs for the Sea Ray 390 Sundancer 2010. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
How many people can each boat hold?
The Sea Ray 390 Sundancer 2010 is Coast Guard rated for 11 passengers, while the Sea Ray 390 Sundancer 2011 is certified for 11. 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.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Sea Ray 390 Sundancer 2010 and Sea Ray 390 Sundancer 2011 share an 12 ft. 6 in. (3.81 m) beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
How do the fuel tanks compare on the Sea Ray 390 Sundancer 2010 and Sea Ray 390 Sundancer 2011?
Both boats carry similar fuel loads — 25 gallons and 25 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Sea Ray 390 Sundancer 2010 and Sea Ray 390 Sundancer 2011 from the same manufacturer?
Yes — both the Sea Ray 390 Sundancer 2010 and the Sea Ray 390 Sundancer 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.
