The Sea Ray 240 Sundeck 2006 vs Sea Ray Sundancer 400 1999 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 Sundancer 400 1999 measures 40,0 feet overall (1999), giving it roughly 14,0 additional feet of deck space compared to the Sea Ray 240 Sundeck 2006 at 26,0 feet (2006). Weight tells a clearer story for trailering families: the Sea Ray Sundancer 400 1999 tips the scales at 22 500 lbs — 22 032 lbs less than the Sea Ray 240 Sundeck 2006 at 468 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 383 hp, the Sea Ray Sundancer 400 1999 has a 63-hp advantage over the Sea Ray 240 Sundeck 2006's 320-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 Sundancer 400 1999 carries 335 gallons versus 65 gallons in the Sea Ray 240 Sundeck 2006. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 12 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
