The Sea Ray 320 Sundancer 2006 vs Sea Ray SLX 280 Outboard 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.

Size is the most obvious dividing line here. The Sea Ray 320 Sundancer 2006 measures 35,0 feet overall (2006), giving it roughly 3,5 additional feet of deck space compared to the Sea Ray SLX 280 Outboard 2023 at 31,5 feet (2023). Weight tells a clearer story for trailering families: the Sea Ray SLX 280 Outboard 2023 tips the scales at 8 053 lbs — 7 915 lbs less than the Sea Ray 320 Sundancer 2006 at 138 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 375 hp, the Sea Ray 320 Sundancer 2006 has a 125-hp advantage over the Sea Ray SLX 280 Outboard 2023'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 SLX 280 Outboard 2023 carries 135 gallons versus 2 gallons in the Sea Ray 320 Sundancer 2006. 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 320 Sundancer 2006 is rated for 10 passengers, while the Sea Ray SLX 280 Outboard 2023 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 320 Sundancer 2006 could be the deciding factor.
