The Sea Ray 280 Sundancer 2009 is a deep-V design and the Sea Ray 47 Sedan Bridge 2010 is a semi-displacement design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

Size is the most obvious dividing line here. The Sea Ray 47 Sedan Bridge 2010 measures 50,7 feet overall (2010), giving it roughly 19,6 additional feet of deck space compared to the Sea Ray 280 Sundancer 2009 at 31,1 feet (2009). Weight tells a clearer story for trailering families: the Sea Ray 47 Sedan Bridge 2010 tips the scales at 37 500 lbs - 28 870 lbs less than the Sea Ray 280 Sundancer 2009 at 8 630 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 2010 has a 199-hp advantage over the Sea Ray 280 Sundancer 2009'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 47 Sedan Bridge 2010 carries 530 gallons versus 100 gallons in the Sea Ray 280 Sundancer 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 47 Sedan Bridge 2010 is rated for 15 passengers, while the Sea Ray 280 Sundancer 2009 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray 47 Sedan Bridge 2010 could be the deciding factor.
