Both the Sea Ray 52 Sedan Bridge 2009 and the Sea Ray 520 Sedan Bridge 2013 are semi-displacement designs, both built in fibreglass, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

Size is the most obvious dividing line here. The Sea Ray 52 Sedan Bridge 2009 measures 57,1 feet overall (2009), giving it roughly 4,8 additional feet of deck space compared to the Sea Ray 520 Sedan Bridge 2013 at 52,3 feet (2013). Weight tells a clearer story for trailering families: the Sea Ray 520 Sedan Bridge 2013 tips the scales at 51 000 lbs - 10 733 lbs less than the Sea Ray 52 Sedan Bridge 2009 at 40 267 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 765 hp, the Sea Ray 52 Sedan Bridge 2009 has a 124-hp advantage over the Sea Ray 520 Sedan Bridge 2013's 641-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 500 gal and 500 gal - so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Sea Ray 52 Sedan Bridge 2009 is rated for 17 passengers, while the Sea Ray 520 Sedan Bridge 2013 caps at 15. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray 52 Sedan Bridge 2009 could be the deciding factor.
