Sea Ray SLX 400 Outboard 2023 vs Sea Ray Sundancer 380 2003 — Same Brand, Different Boat

The Sea Ray SLX 400 Outboard 2023 vs Sea Ray Sundancer 380 2003 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 SLX 400 Outboard 2023 at 41,1 ft versus Sea Ray Sundancer 380 2003 at 42,0 ft. Weight tells a clearer story for trailering families: the Sea Ray Sundancer 380 2003 tips the scales at 20 000 lbs — 1 463 lbs less than the Sea Ray SLX 400 Outboard 2023 at 18 537 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 350 hp, the Sea Ray Sundancer 380 2003 has a 50-hp advantage over the Sea Ray SLX 400 Outboard 2023's 300-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Sea Ray SLX 400 Outboard 2023 carries 375 gallons versus 275 gallons in the Sea Ray Sundancer 380 2003. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 12 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 Sundancer 380 2003 and its 350-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Sea Ray SLX 400 Outboard 2023 with its 300-hp rating is the more economical daily driver.

Sea Ray SLX 400 Outboard 2023 vs Sea Ray Sundancer 380 2003 — Common Questions

Which is the larger boat — the Sea Ray SLX 400 Outboard 2023 or the Sea Ray Sundancer 380 2003?
The Sea Ray Sundancer 380 2003 is the longer of the two at 42,0 feet overall. The Sea Ray SLX 400 Outboard 2023 comes in at 41,1 feet, making it roughly 0,9 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sea Ray SLX 400 Outboard 2023 or the Sea Ray Sundancer 380 2003?
For trailering, the Sea Ray SLX 400 Outboard 2023 has the edge at 18 537 lbs dry weight versus 20 000 lbs for the Sea Ray Sundancer 380 2003. 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 Sundancer 380 2003 is rated to a maximum of 350 hp, giving it the larger power ceiling. The Sea Ray SLX 400 Outboard 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 SLX 400 Outboard 2023 is Coast Guard rated for 12 passengers, while the Sea Ray Sundancer 380 2003 is certified for 12. 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 380 2003 measures 156" wide, compared to 145" for the Sea Ray SLX 400 Outboard 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.
Which boat has the larger fuel tank — the Sea Ray SLX 400 Outboard 2023 or the Sea Ray Sundancer 380 2003?
The Sea Ray SLX 400 Outboard 2023 has the bigger tank at 375 gallons, versus 275 gallons on the Sea Ray Sundancer 380 2003. That 100-gallon difference translates to roughly 300–500 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Sea Ray SLX 400 Outboard 2023 and Sea Ray Sundancer 380 2003 from the same manufacturer?
Yes — both the Sea Ray SLX 400 Outboard 2023 and the Sea Ray Sundancer 380 2003 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.
