When two boats share the same hull type — in this case both the Sea Ray 47 Sedan Bridge 2011 and the Sea Ray 48 Sundancer 2008 are semi displacement designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

On paper these two are close siblings in the size department — Sea Ray 47 Sedan Bridge 2011 at 50,7 ft versus Sea Ray 48 Sundancer 2008 at 51,0 ft. Weight tells a clearer story for trailering families: the Sea Ray 48 Sundancer 2008 tips the scales at 3 425 lbs — 3 050 lbs less than the Sea Ray 47 Sedan Bridge 2011 at 375 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 574 hp, the Sea Ray 47 Sedan Bridge 2011 has a 57-hp advantage over the Sea Ray 48 Sundancer 2008'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 2011 carries 53 gallons versus 4 gallons in the Sea Ray 48 Sundancer 2008. 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.
