The Sea Ray 390 Motor Yacht 2005 vs Sea Ray 520 Sedan Bridge 2012 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.

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 Sea Ray 520 Sedan Bridge 2012 tops out at 764 hp. Engine specs for the Sea Ray 390 Motor Yacht 2005 aren't listed — confirm with a dealer before selecting an outboard.Both carry nearly identical fuel loads — 3 gal and 5 gal — so range won't be a tiebreaker here.
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 390 Motor Yacht 2005 caps at 12. 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. The Sea Ray 390 Motor Yacht 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 12 that costs less to run day-to-day.
