Both the Sea Ray 390 Sundancer 2010 and the Sea Ray 390 Sundancer 2011 are semi-displacement designs, both built in fibreglass, so 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 24 600 lbs and 24 600 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 - 250 gal and 250 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.
