Sea Ray SLX 350 2023 vs Sea Ray Sundancer 320 2022 — Same Brand, Different Boat

The Sea Ray SLX 350 2023 vs Sea Ray Sundancer 320 2022 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 350 2023 at 34,7 ft versus Sea Ray Sundancer 320 2022 at 35,4 ft. Weight tells a clearer story for trailering families: the Sea Ray Sundancer 320 2022 tips the scales at 14 000 lbs — 110 lbs less than the Sea Ray SLX 350 2023 at 13 890 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.

Both boats share a closely matched power ceiling — 300 hp for the Sea Ray SLX 350 2023 and 300 hp for the Sea Ray Sundancer 320 2022. 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. Fuel capacity breaks the other way: the Sea Ray SLX 350 2023 carries 177 gallons versus 158 gallons in the Sea Ray Sundancer 320 2022. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 10 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 SLX 350 2023 and Sea Ray Sundancer 320 2022 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 SLX 350 2023 vs Sea Ray Sundancer 320 2022 — Common Questions

Which is the larger boat — the Sea Ray SLX 350 2023 or the Sea Ray Sundancer 320 2022?
The Sea Ray Sundancer 320 2022 is the longer of the two at 35,4 feet overall. The Sea Ray SLX 350 2023 comes in at 34,7 feet, making it roughly 0,7 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sea Ray SLX 350 2023 or the Sea Ray Sundancer 320 2022?
For trailering, the Sea Ray SLX 350 2023 has the edge at 13 890 lbs dry weight versus 14 000 lbs for the Sea Ray Sundancer 320 2022. 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 SLX 350 2023 is Coast Guard rated for 10 passengers, while the Sea Ray Sundancer 320 2022 is certified for 10. 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 320 2022 measures 128" wide, compared to 127" for the Sea Ray SLX 350 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 350 2023 or the Sea Ray Sundancer 320 2022?
The Sea Ray SLX 350 2023 has the bigger tank at 177 gallons, versus 158 gallons on the Sea Ray Sundancer 320 2022. That 19-gallon difference translates to roughly 57–95 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Sea Ray SLX 350 2023 and Sea Ray Sundancer 320 2022 from the same manufacturer?
Yes — both the Sea Ray SLX 350 2023 and the Sea Ray Sundancer 320 2022 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.
