Sea Ray 390 Sundancer 2012 vs Sea Ray Sundancer 370 2023: Same Brand, Different Boat

The Sea Ray 390 Sundancer 2012 vs Sea Ray Sundancer 370 2023 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.

On paper these two are close siblings in the size department - Sea Ray 390 Sundancer 2012 at 39,0 ft versus Sea Ray Sundancer 370 2023 at 37,2 ft. Weight tells a clearer story for trailering families: the Sea Ray 390 Sundancer 2012 tips the scales at 24 600 lbs - 3 800 lbs more than the Sea Ray Sundancer 370 2023 at 20 800 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 425 hp, the Sea Ray 390 Sundancer 2012 has a 125-hp advantage over the Sea Ray Sundancer 370 2023's 300-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. 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.

Bottom line: Performance buyers should lean toward the Sea Ray 390 Sundancer 2012 and its 425-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Sea Ray Sundancer 370 2023 with its 300-hp rating is the more economical daily driver.

Sea Ray 390 Sundancer 2012 vs Sea Ray Sundancer 370 2023 - Common Questions

Which is the larger boat - the Sea Ray 390 Sundancer 2012 or the Sea Ray Sundancer 370 2023?
The Sea Ray 390 Sundancer 2012 is the longer of the two at 39,0 feet overall. The Sea Ray Sundancer 370 2023 comes in at 37,2 feet, making it roughly 1,8 ft shorter - a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer - the Sea Ray 390 Sundancer 2012 or the Sea Ray Sundancer 370 2023?
For trailering, the Sea Ray Sundancer 370 2023 has the edge at 20 800 lbs dry weight versus 24 600 lbs for the Sea Ray 390 Sundancer 2012. 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.
Which boat can handle a bigger outboard?
The Sea Ray 390 Sundancer 2012 is rated to a maximum of 425 hp, giving it the larger power ceiling. The Sea Ray Sundancer 370 2023 tops out at 300 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 2012 is Coast Guard rated for 11 passengers, while the Sea Ray Sundancer 370 2023 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.
Which boat is wider, and does it affect trailering?
The Sea Ray 390 Sundancer 2012 measures 150" wide, compared to 144" for the Sea Ray Sundancer 370 2023. 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.
How do the fuel tanks compare on the Sea Ray 390 Sundancer 2012 and Sea Ray Sundancer 370 2023?
Both boats carry similar fuel loads - 250 gallons and 250 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 2012 and Sea Ray Sundancer 370 2023 from the same manufacturer?
Yes - both the Sea Ray 390 Sundancer 2012 and the Sea Ray Sundancer 370 2023 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.
