The Sea Ray 350 Sundancer 2011 is a deep-V design and the Sea Ray 450 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 450 Sedan Bridge 2010 measures 45,4 feet overall (2010), giving it roughly 9,9 additional feet of deck space compared to the Sea Ray 350 Sundancer 2011 at 35,5 feet (2011). Weight tells a clearer story for trailering families: the Sea Ray 450 Sedan Bridge 2010 tips the scales at 28 500 lbs - 13 100 lbs less than the Sea Ray 350 Sundancer 2011 at 15 400 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 478 hp, the Sea Ray 450 Sedan Bridge 2010 has a 103-hp advantage over the Sea Ray 350 Sundancer 2011'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 450 Sedan Bridge 2010 carries 350 gallons versus 225 gallons in the Sea Ray 350 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 450 Sedan Bridge 2010 is rated for 13 passengers, while the Sea Ray 350 Sundancer 2011 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray 450 Sedan Bridge 2010 could be the deciding factor.
