Matching a modified vee Sea Ray 175 Sport 2011 against a semi displacement Sea Ray 500 Sundancer 2010 means you're likely deciding between two genuinely 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 500 Sundancer 2010 measures 51,0 feet overall (2010), giving it roughly 33,5 additional feet of deck space compared to the Sea Ray 175 Sport 2011 at 17,5 feet (2011). Weight tells a clearer story for trailering families: the Sea Ray 500 Sundancer 2010 tips the scales at 3 425 lbs — 3 404 lbs less than the Sea Ray 175 Sport 2011 at 21 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 500 Sundancer 2010 has a 439-hp advantage over the Sea Ray 175 Sport 2011's 135-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 175 Sport 2011 carries 21 gallons versus 4 gallons in the Sea Ray 500 Sundancer 2010. 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 500 Sundancer 2010 is rated for 15 passengers, while the Sea Ray 175 Sport 2011 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray 500 Sundancer 2010 could be the deciding factor.
