Sea Ray 370 Sundancer 2013 vs Sea Ray 420 Sedan Bridge 2005 — Same Brand, Different Boat

The Sea Ray 370 Sundancer 2013 vs Sea Ray 420 Sedan Bridge 2005 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

Size is the most obvious dividing line here. The Sea Ray 420 Sedan Bridge 2005 measures 45,0 feet overall (2005), giving it roughly 7,5 additional feet of deck space compared to the Sea Ray 370 Sundancer 2013 at 37,5 feet (2013). Weight tells a clearer story for trailering families: the Sea Ray 370 Sundancer 2013 tips the scales at 18 064 lbs — 17 779 lbs more than the Sea Ray 420 Sedan Bridge 2005 at 285 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 Sea Ray 370 Sundancer 2013 carries a rated maximum of 380 hp. Engine data for the Sea Ray 420 Sedan Bridge 2005 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Sea Ray 370 Sundancer 2013 carries 225 gallons versus 35 gallons in the Sea Ray 420 Sedan Bridge 2005. 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 420 Sedan Bridge 2005 is rated for 13 passengers, while the Sea Ray 370 Sundancer 2013 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 420 Sedan Bridge 2005 could be the deciding factor.

Bottom line: Choose the Sea Ray 420 Sedan Bridge 2005 if your priority is putting more people on the water — it handles 13 passengers and at 45,0 ft it has the deck room to back that rating up comfortably. The Sea Ray 370 Sundancer 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 11 that costs less to run day-to-day.

The Sea Ray 420 Sedan Bridge 2005 is the longer of the two at 45,0 feet overall. The Sea Ray 370 Sundancer 2013 comes in at 37,5 feet, making it roughly 7,5 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sea Ray 370 Sundancer 2013 or the Sea Ray 420 Sedan Bridge 2005?
For trailering, the Sea Ray 420 Sedan Bridge 2005 has the edge at 285 lbs dry weight versus 18 064 lbs for the Sea Ray 370 Sundancer 2013. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows.

The Sea Ray 370 Sundancer 2013 is Coast Guard rated for 11 passengers, while the Sea Ray 420 Sedan Bridge 2005 is certified for 13. 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.

The Sea Ray 420 Sedan Bridge 2005 measures 171" wide, compared to 144" for the Sea Ray 370 Sundancer 2013. 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.

The Sea Ray 370 Sundancer 2013 has the bigger tank at 225 gallons, versus 35 gallons on the Sea Ray 420 Sedan Bridge 2005. That 190-gallon difference translates to roughly 570–950 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Yes — both the Sea Ray 370 Sundancer 2013 and the Sea Ray 420 Sedan Bridge 2005 are built by Sea Ray. That means shared dealer networks, common parts availability, and consistent build quality across the line.
