Matching a modified vee Sea Ray 230 Select 2009 against a semi displacement Sea Ray 500 Sundancer 2011 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 2011 measures 51,0 feet overall (2011), giving it roughly 28,0 additional feet of deck space compared to the Sea Ray 230 Select 2009 at 23,0 feet (2009). Weight tells a clearer story for trailering families: the Sea Ray 230 Select 2009 tips the scales at 4 244 lbs — 819 lbs more than the Sea Ray 500 Sundancer 2011 at 3 425 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 576 hp, the Sea Ray 500 Sundancer 2011 has a 256-hp advantage over the Sea Ray 230 Select 2009's 320-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 5 gal and 4 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Sea Ray 500 Sundancer 2011 is rated for 15 passengers, while the Sea Ray 230 Select 2009 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 500 Sundancer 2011 could be the deciding factor.
