The X-Yachts X-40 Standard Standard 2004 vs X-Yachts X-79 1979 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.

Weight tells a clearer story for trailering families: the X-Yachts X-40 Standard Standard 2004 tips the scales at 16 424 lbs — 13 459 lbs more than the X-Yachts X-79 1979 at 2 965 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 X-Yachts X-40 Standard Standard 2004 carries a rated maximum of 40 hp. Engine data for the X-Yachts X-79 1979 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.

If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the X-Yachts X-40 Standard Standard 2004 could be the deciding factor.

That gap separates two entirely different categories of sailing: the heavier boat is built for offshore passage-making and load-carrying, while the lighter hull rewards performance sailing and easier handling in lighter air.

The X-Yachts X-40 Standard Standard 2004 draws 6,1 ft, compared to 4,5 ft for the X-Yachts X-79 1979.
