Detailed Evaluation & Buyer Recommendation

Sea Ray 300 Select EX 2008 vs Sea Ray 520 Sedan Bridge 2013 — Same Brand, Different Boat

Matching a modified vee Sea Ray 300 Select EX 2008 against a semi displacement Sea Ray 520 Sedan Bridge 2013 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

The power gap is worth calling out. Rated to 641 hp, the Sea Ray 520 Sedan Bridge 2013 has a 321-hp advantage over the Sea Ray 300 Select EX 2008's 320-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 Select EX 2008 carries 13 gallons versus 5 gallons in the Sea Ray 520 Sedan Bridge 2013. 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 300 Select EX 2008 caps at 8. 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 300 Select EX 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
