Detailed Evaluation & Buyer Recommendation
Sea Ray 370 Sundancer 2012 vs Sea Ray 520 Sedan Bridge 2012 — Same Brand, Different Boat
Matching a deep vee Sea Ray 370 Sundancer 2012 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 14,8 additional feet of deck space compared to the Sea Ray 370 Sundancer 2012 at 37,5 feet (2012). Weight tells a clearer story for trailering families: the Sea Ray 370 Sundancer 2012 tips the scales at 18 064 lbs — 18 022 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 384-hp advantage over the Sea Ray 370 Sundancer 2012's 380-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 370 Sundancer 2012 carries 225 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 370 Sundancer 2012 caps at 11. 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 370 Sundancer 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 11 that costs less to run day-to-day.
