The Sea Ray 290 Amberjack 2007 vs Sea Ray Sundancer 310 2011 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.

On paper these two are close siblings in the size department — Sea Ray 290 Amberjack 2007 at 31,0 ft versus Sea Ray Sundancer 310 2011 at 31,0 ft. Weight tells a clearer story for trailering families: the Sea Ray Sundancer 310 2011 tips the scales at 11 630 lbs — 11 517 lbs less than the Sea Ray 290 Amberjack 2007 at 113 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 300 hp, the Sea Ray 290 Amberjack 2007 has a 40-hp advantage over the Sea Ray Sundancer 310 2011's 260-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 310 2011 carries 125 gallons versus 23 gallons in the Sea Ray 290 Amberjack 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 9 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.
