Sea Ray 340 Sundancer 2007 vs Sea Ray 58 Sedan Bridge 2008: Same Brand, Different Boat

The Sea Ray 340 Sundancer 2007 vs Sea Ray 58 Sedan Bridge 2008 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 58 Sedan Bridge 2008 measures 58,0 feet overall (2008), giving it roughly 21,0 additional feet of deck space compared to the Sea Ray 340 Sundancer 2007 at 37,0 feet (2007). Weight tells a clearer story for trailering families: the Sea Ray 58 Sedan Bridge 2008 tips the scales at 51 500 lbs - 36 000 lbs less than the Sea Ray 340 Sundancer 2007 at 15 500 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 862 hp, the Sea Ray 58 Sedan Bridge 2008 has a 487-hp advantage over the Sea Ray 340 Sundancer 2007's 375-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 58 Sedan Bridge 2008 carries 700 gallons versus 225 gallons in the Sea Ray 340 Sundancer 2007. 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 58 Sedan Bridge 2008 is rated for 17 passengers, while the Sea Ray 340 Sundancer 2007 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 58 Sedan Bridge 2008 could be the deciding factor.

Bottom line: Choose the Sea Ray 58 Sedan Bridge 2008 if your priority is putting more people on the water - it handles 17 passengers and at 58,0 ft it has the deck room to back that rating up comfortably. The Sea Ray 340 Sundancer 2007 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 340 Sundancer 2007 vs Sea Ray 58 Sedan Bridge 2008 - Common Questions

Which is the larger boat - the Sea Ray 340 Sundancer 2007 or the Sea Ray 58 Sedan Bridge 2008?
The Sea Ray 58 Sedan Bridge 2008 is the longer of the two at 58,0 feet overall. The Sea Ray 340 Sundancer 2007 comes in at 37,0 feet, making it roughly 21,0 ft shorter - a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer - the Sea Ray 340 Sundancer 2007 or the Sea Ray 58 Sedan Bridge 2008?
For trailering, the Sea Ray 340 Sundancer 2007 has the edge at 15 500 lbs dry weight versus 51 500 lbs for the Sea Ray 58 Sedan Bridge 2008. 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 58 Sedan Bridge 2008 is rated to a maximum of 862 hp, giving it the larger power ceiling. The Sea Ray 340 Sundancer 2007 tops out at 375 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 340 Sundancer 2007 is Coast Guard rated for 11 passengers, while the Sea Ray 58 Sedan Bridge 2008 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 58 Sedan Bridge 2008 measures 192" wide, compared to 144" for the Sea Ray 340 Sundancer 2007. 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 340 Sundancer 2007 or the Sea Ray 58 Sedan Bridge 2008?
The Sea Ray 58 Sedan Bridge 2008 has the bigger tank at 700 gallons, versus 225 gallons on the Sea Ray 340 Sundancer 2007. That 475-gallon difference translates to roughly 1425–2375 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Sea Ray 340 Sundancer 2007 and Sea Ray 58 Sedan Bridge 2008 from the same manufacturer?
Yes - both the Sea Ray 340 Sundancer 2007 and the Sea Ray 58 Sedan Bridge 2008 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.
