The Sea Ray 300 SLX® 2013 vs Sea Ray Sunsport 230 2021 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 300 SLX® 2013 measures 29,5 feet overall (2013), giving it roughly 5,9 additional feet of deck space compared to the Sea Ray Sunsport 230 2021 at 23,6 feet (2021). Weight tells a clearer story for trailering families: the Sea Ray Sunsport 230 2021 tips the scales at 4 890 lbs — 4 813 lbs less than the Sea Ray 300 SLX® 2013 at 77 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 380 hp, the Sea Ray 300 SLX® 2013 has a 130-hp advantage over the Sea Ray Sunsport 230 2021'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 300 SLX® 2013 carries 13 gallons versus 5 gallons in the Sea Ray Sunsport 230 2021. 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 300 SLX® 2013 is rated for 8 passengers, while the Sea Ray Sunsport 230 2021 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray 300 SLX® 2013 could be the deciding factor.
