Matching a deep vee Sea Ray 21 Jet 2013 against a semi displacement Sea Ray 520 Sedan Bridge 2012 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.

Size is the most obvious dividing line here. The Sea Ray 520 Sedan Bridge 2012 measures 52,3 feet overall (2012), giving it roughly 30,8 additional feet of deck space compared to the Sea Ray 21 Jet 2013 at 21,5 feet (2013). Weight tells a clearer story for trailering families: the Sea Ray 21 Jet 2013 tips the scales at 2 883 lbs — 2 841 lbs more than the Sea Ray 520 Sedan Bridge 2012 at 42 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 764 hp, the Sea Ray 520 Sedan Bridge 2012 has a 644-hp advantage over the Sea Ray 21 Jet 2013's 120-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 21 Jet 2013 carries 45 gallons versus 5 gallons in the Sea Ray 520 Sedan Bridge 2012. 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 2012 is rated for 15 passengers, while the Sea Ray 21 Jet 2013 caps at 10. 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.
