Detailed Evaluation & Buyer Recommendation
Sea Ray 520 Sedan Bridge 2013 vs Sea Ray SLX 250 2022: Same Brand, Different Boat
The Sea Ray 520 Sedan Bridge 2013 vs Sea Ray SLX 250 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 520 Sedan Bridge 2013 measures 52,3 feet overall (2013), giving it roughly 26,7 additional feet of deck space compared to the Sea Ray SLX 250 2022 at 25,6 feet (2022). Weight tells a clearer story for trailering families: the Sea Ray 520 Sedan Bridge 2013 tips the scales at 51 000 lbs - 45 200 lbs more than the Sea Ray SLX 250 2022 at 5 800 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 641 hp, the Sea Ray 520 Sedan Bridge 2013 has a 341-hp advantage over the Sea Ray SLX 250 2022's 300-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 520 Sedan Bridge 2013 carries 500 gallons versus 75 gallons in the Sea Ray SLX 250 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 520 Sedan Bridge 2013 is rated for 15 passengers, while the Sea Ray SLX 250 2022 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 520 Sedan Bridge 2013 could be the deciding factor.
Bottom line: Choose the Sea Ray 520 Sedan Bridge 2013 if your priority is putting more people on the water - it handles 15 passengers and at 52,3 ft it has the deck room to back that rating up comfortably. The Sea Ray SLX 250 2022 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
