The Sea Ray 520 Sedan Bridge 2012 vs Sea Ray Sun Sport 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.
The Sea Ray 520 Sedan Bridge 2012 carries a rated maximum of 764 hp. Engine data for the Sea Ray Sun Sport 230 2021 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.
For family outings this is probably the sharpest distinction between the two. The Sea Ray 520 Sedan Bridge 2012 is rated for 15 passengers, while the Sea Ray Sun Sport 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 520 Sedan Bridge 2012 could be the deciding factor.
Bottom line: Choose the Sea Ray 520 Sedan Bridge 2012 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.
