Sea Ray 370 Sundancer 2011 vs Sea Ray 580 Sedan Bridge 2012 — Same Brand, Different Boat

Matching a deep vee Sea Ray 370 Sundancer 2011 against a semi displacement Sea Ray 580 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 580 Sedan Bridge 2012 measures 58,6 feet overall (2012), giving it roughly 21,1 additional feet of deck space compared to the Sea Ray 370 Sundancer 2011 at 37,5 feet (2011). Weight tells a clearer story for trailering families: the Sea Ray 370 Sundancer 2011 tips the scales at 18 064 lbs — 17 549 lbs more than the Sea Ray 580 Sedan Bridge 2012 at 515 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 861 hp, the Sea Ray 580 Sedan Bridge 2012 has a 481-hp advantage over the Sea Ray 370 Sundancer 2011'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 2011 carries 225 gallons versus 7 gallons in the Sea Ray 580 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 580 Sedan Bridge 2012 is rated for 17 passengers, while the Sea Ray 370 Sundancer 2011 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 580 Sedan Bridge 2012 could be the deciding factor.

Bottom line: Choose the Sea Ray 580 Sedan Bridge 2012 if your priority is putting more people on the water — it handles 17 passengers and at 58,6 ft it has the deck room to back that rating up comfortably. The Sea Ray 370 Sundancer 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 11 that costs less to run day-to-day.

Sea Ray 370 Sundancer 2011 vs Sea Ray 580 Sedan Bridge 2012 — Common Questions

Which is the larger boat — the Sea Ray 370 Sundancer 2011 or the Sea Ray 580 Sedan Bridge 2012?
The Sea Ray 580 Sedan Bridge 2012 is the longer of the two at 58,6 feet overall. The Sea Ray 370 Sundancer 2011 comes in at 37,5 feet, making it roughly 21,1 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sea Ray 370 Sundancer 2011 or the Sea Ray 580 Sedan Bridge 2012?
For trailering, the Sea Ray 580 Sedan Bridge 2012 has the edge at 515 lbs dry weight versus 18 064 lbs for the Sea Ray 370 Sundancer 2011. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Sea Ray 580 Sedan Bridge 2012 is rated to a maximum of 861 hp, giving it the larger power ceiling. The Sea Ray 370 Sundancer 2011 tops out at 380 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Sea Ray 370 Sundancer 2011 is Coast Guard rated for 11 passengers, while the Sea Ray 580 Sedan Bridge 2012 is certified for 17. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Sea Ray 580 Sedan Bridge 2012 measures 192" wide, compared to 144" for the Sea Ray 370 Sundancer 2011. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Sea Ray 370 Sundancer 2011 or the Sea Ray 580 Sedan Bridge 2012?
The Sea Ray 370 Sundancer 2011 has the bigger tank at 225 gallons, versus 7 gallons on the Sea Ray 580 Sedan Bridge 2012. That 218-gallon difference translates to roughly 654–1090 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Sea Ray 370 Sundancer 2011 and Sea Ray 580 Sedan Bridge 2012 from the same manufacturer?
Yes — both the Sea Ray 370 Sundancer 2011 and the Sea Ray 580 Sedan Bridge 2012 are built by Sea Ray. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
