The Sea Ray 300 Select EX 2009 vs Sea Ray 38 Sundancer 2007 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

Size is the most obvious dividing line here. The Sea Ray 38 Sundancer 2007 measures 39,0 feet overall (2007), giving it roughly 9,5 additional feet of deck space compared to the Sea Ray 300 Select EX 2009 at 29,5 feet (2009). Weight tells a clearer story for trailering families: the Sea Ray 38 Sundancer 2007 tips the scales at 194 lbs — 117 lbs less than the Sea Ray 300 Select EX 2009 at 77 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 640 hp, the Sea Ray 300 Select EX 2009 has a 220-hp advantage over the Sea Ray 38 Sundancer 2007's 420-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 38 Sundancer 2007 carries 25 gallons versus 13 gallons in the Sea Ray 300 Select EX 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 38 Sundancer 2007 is rated for 11 passengers, while the Sea Ray 300 Select EX 2009 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray 38 Sundancer 2007 could be the deciding factor.
