Sea Ray 47 Sedan Bridge 2008 vs Sea Ray 48 Sundancer 2006 — Same Brand, Different Boat

The Sea Ray 47 Sedan Bridge 2008 vs Sea Ray 48 Sundancer 2006 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 48 Sundancer 2006 measures 51,0 feet overall (2006), giving it roughly 46,0 additional feet of deck space compared to the Sea Ray 47 Sedan Bridge 2008 at 5,0 feet (2008). At 375 lbs and 336 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The power gap is worth calling out. Rated to 574 hp, the Sea Ray 47 Sedan Bridge 2008 has a 57-hp advantage over the Sea Ray 48 Sundancer 2006's 517-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 47 Sedan Bridge 2008 carries 53 gallons versus 4 gallons in the Sea Ray 48 Sundancer 2006. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 15 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: The Sea Ray 48 Sundancer 2006 at 51,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Sea Ray 47 Sedan Bridge 2008 at 5,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.

Sea Ray 47 Sedan Bridge 2008 vs Sea Ray 48 Sundancer 2006 — Common Questions

Which is the larger boat — the Sea Ray 47 Sedan Bridge 2008 or the Sea Ray 48 Sundancer 2006?
The Sea Ray 48 Sundancer 2006 is the longer of the two at 51,0 feet overall. The Sea Ray 47 Sedan Bridge 2008 comes in at 5,0 feet, making it roughly 46,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sea Ray 47 Sedan Bridge 2008 or the Sea Ray 48 Sundancer 2006?
For trailering, the Sea Ray 48 Sundancer 2006 has the edge at 336 lbs dry weight versus 375 lbs for the Sea Ray 47 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 47 Sedan Bridge 2008 is rated to a maximum of 574 hp, giving it the larger power ceiling. The Sea Ray 48 Sundancer 2006 tops out at 517 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 47 Sedan Bridge 2008 is Coast Guard rated for 15 passengers, while the Sea Ray 48 Sundancer 2006 is certified for 15. 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.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Sea Ray 47 Sedan Bridge 2008 and Sea Ray 48 Sundancer 2006 share an 14 ft. 8 in. (4.47 m) beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
Which boat has the larger fuel tank — the Sea Ray 47 Sedan Bridge 2008 or the Sea Ray 48 Sundancer 2006?
The Sea Ray 47 Sedan Bridge 2008 has the bigger tank at 53 gallons, versus 4 gallons on the Sea Ray 48 Sundancer 2006. That 49-gallon difference translates to roughly 147–245 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Sea Ray 47 Sedan Bridge 2008 and Sea Ray 48 Sundancer 2006 from the same manufacturer?
Yes — both the Sea Ray 47 Sedan Bridge 2008 and the Sea Ray 48 Sundancer 2006 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.
