The Sea Ray 350 Sundancer 2008 vs Sea Ray SLX 310 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.

Size is the most obvious dividing line here. The Sea Ray 350 Sundancer 2008 measures 37,0 feet overall (2008), giving it roughly 5,4 additional feet of deck space compared to the Sea Ray SLX 310 2022 at 31,6 feet (2022). Weight tells a clearer story for trailering families: the Sea Ray 350 Sundancer 2008 tips the scales at 18 064 lbs — 7 277 lbs more than the Sea Ray SLX 310 2022 at 10 787 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 301 hp, the Sea Ray 350 Sundancer 2008 has a 51-hp advantage over the Sea Ray SLX 310 2022's 250-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 350 Sundancer 2008 carries 225 gallons versus 13 gallons in the Sea Ray SLX 310 2022. 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 350 Sundancer 2008 is rated for 11 passengers, while the Sea Ray SLX 310 2022 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray 350 Sundancer 2008 could be the deciding factor.
