The shipyard was founded in 1979 by the brothers Lars Jeppesen, Niels Jeppesen and their friend Birger Hansen. The first boat, the X-79, got its name due to the length of the boat, which was 7.9 m (7.96 m), and because it was launched in the year of 1979. The boat was the Danish answer to J/24, Albin Express, and Maxi 80 Racer and has won many regattas since the first launch. A total of 468 X-79 were built between 1979 and 1994. The yard builds approximately 150 boats per year. The yard has built over 6,000 boats to clients worldwide since 1979.

X-Yachts employs a total of 100 people at the headquarter in Haderslev and has its own moulding production in Poland as well. X-Yachts has a global dealer network consisting of 40 independent dealers. In total X-Yachts employs over 250 people worldwide.

The majority shareholder of X-Yachts and owner since 2012 is Ib Kunøe's holding company Consolidated Holdings, which operates through a number of wholly or partly owned companies. X-Yachts current CEO, since 2018, is Kræn Brinck Nielsen.

Although the first boat was designed for regattas, the yard's main area is cruising boats, and today represents three series of sailing boats: Xcruising, Xperformance, and latest Pure X.
