Sea Ray Sundancer 370 2023 vs Sea Ray Sunsport 290 2003 — Same Brand, Different Boat

The Sea Ray Sundancer 370 2023 vs Sea Ray Sunsport 290 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.

Both boats share a closely matched power ceiling — 300 hp for the Sea Ray Sundancer 370 2023 and 300 hp for the Sea Ray Sunsport 290 2003. 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 Sundancer 370 2023 carries 25 gallons versus 13 gallons in the Sea Ray Sunsport 290 2003. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Sea Ray Sundancer 370 2023 is rated for 11 passengers, while the Sea Ray Sunsport 290 2003 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray Sundancer 370 2023 could be the deciding factor.

Bottom line: Choose the Sea Ray Sundancer 370 2023 if your priority is putting more people on the water — it handles 11 passengers and at 37,2 ft it has the deck room to back that rating up comfortably. The Sea Ray Sunsport 290 2003 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
