The X-Yachts X-402 1984 vs X-Yachts X-50 Standard Standard 2004 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 X-Yachts X-50 Standard Standard 2004 measures 50,0 feet overall (2004), giving it roughly 10,2 additional feet of deck space compared to the X-Yachts X-402 1984 at 39,8 feet (1984). Weight tells a clearer story for trailering families: the X-Yachts X-50 Standard Standard 2004 tips the scales at 27 337 lbs - 14 109 lbs less than the X-Yachts X-402 1984 at 13 228 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 75 hp, the X-Yachts X-50 Standard Standard 2004 has a 35-hp advantage over the X-Yachts X-402 1984's 40-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The X-Yachts X-50 Standard Standard 2004 is rated for 15 passengers, while the X-Yachts X-402 1984 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the X-Yachts X-50 Standard Standard 2004 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The X-Yachts X-50 Standard Standard 2004 displaces 27 337 lbs - a 14 109-lb difference over the X-Yachts X-402 1984 at 13 228 lbs. 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.
Draft is a practical consideration that many buyers underestimate until they're already at the marina. The X-Yachts X-50 Standard Standard 2004 draws 9,1 ft, compared to 7,5 ft for the X-Yachts X-402 1984. That 1,6-foot difference affects which anchorages you can access, which haul-out facilities will take you, and how carefully you need to read the tide tables in shallower cruising grounds.
The X-Yachts X-402 1984 is rigged as a fractional_rig_sloop while the X-Yachts X-50 Standard Standard 2004 carries Sloop rigging - a meaningful difference in sail handling complexity, upwind performance, and the size of crew you'll need to work the boat comfortably. Helm style differs too: the X-Yachts X-402 1984 uses a 1 wheel versus a 2 wheels on the X-Yachts X-50 Standard Standard 2004. Wheel helms give better leverage and visibility on larger boats; tillers offer direct feedback and simplicity on smaller ones. For auxiliary power the X-Yachts X-50 Standard Standard 2004 carries a 75-hp engine against 40 hp on the X-Yachts X-402 1984. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.
Hull speed is rated at 8,8 knots for the X-Yachts X-50 Standard Standard 2004 and 7,7 knots for the X-Yachts X-402 1984.
Bottom line: The X-Yachts X-50 Standard Standard 2004 is the offshore and bluewater choice - at 27 337 lbs displacement and 50 ft it has the load capacity, range, and seakeeping for extended passages. The X-Yachts X-402 1984 at 13 228 lbs is the more nimble, accessible option - easier to single-hand and better suited to coastal and inland sailing.
