Both the Sea Ray 36 Sedan Bridge 2009 and the Sea Ray 470 Sundancer® 2012 are semi-displacement designs, both built in fibreglass, so 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?

Size is the most obvious dividing line here. The Sea Ray 470 Sundancer® 2012 measures 47,3 feet overall (2012), giving it roughly 8,9 additional feet of deck space compared to the Sea Ray 36 Sedan Bridge 2009 at 38,3 feet (2009). Weight tells a clearer story for trailering families: the Sea Ray 470 Sundancer® 2012 tips the scales at 28 500 lbs - 6 500 lbs less than the Sea Ray 36 Sedan Bridge 2009 at 22 000 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 459 hp, the Sea Ray 470 Sundancer® 2012 has a 89-hp advantage over the Sea Ray 36 Sedan Bridge 2009's 370-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 470 Sundancer® 2012 carries 350 gallons versus 300 gallons in the Sea Ray 36 Sedan Bridge 2009. 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® 2012 is rated for 14 passengers, while the Sea Ray 36 Sedan Bridge 2009 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 470 Sundancer® 2012 could be the deciding factor.
