When two boats share the same hull type — in this case both the Sea Ray 450 Sedan Bridge 2013 and the Sea Ray 470 Sundancer® 2011 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 450 Sedan Bridge 2013 at 45,6 ft versus Sea Ray 470 Sundancer® 2011 at 47,3 ft. Weight tells a clearer story for trailering families: the Sea Ray 450 Sedan Bridge 2013 tips the scales at 36 602 lbs — 36 317 lbs more than the Sea Ray 470 Sundancer® 2011 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 power gap is worth calling out. Rated to 480 hp, the Sea Ray 450 Sedan Bridge 2013 has a 21-hp advantage over the Sea Ray 470 Sundancer® 2011's 459-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 450 Sedan Bridge 2013 carries 375 gallons versus 35 gallons in the Sea Ray 470 Sundancer® 2011. 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 470 Sundancer® 2011 is rated for 14 passengers, while the Sea Ray 450 Sedan Bridge 2013 caps at 13. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray 470 Sundancer® 2011 could be the deciding factor.
