About Heesen Yachts

Semi-custom

Dutch superyacht yard at Oss, founded by Frans Heesen in 1978, building aluminium and steel motor yachts entirely in-house — five semi-custom Heesen Series platforms from 50 to 57 metres, built on speculation for short delivery, alongside Smart Custom and Full Custom yachts.

In 1978 the entrepreneur Frans Heesen took over an existing shipyard in Oss harbour and began producing aluminium Striker boats. A year later the 20-metre Amigo was launched, the first yacht to bear the Heesen name, and Heesen Shipyards was born. The 38-metre Octopussy of 1988, at over 50 knots the fastest luxury yacht in the world, was the yard's worldwide breakthrough. In 1992 the 50-metre Achiever, built for long voyages, became the first of many steel displacement yachts, and in 1996 Obsessions was, when launched, the largest and most powerful sport fisherman in the world. An expansion in 2008 raised capacity to up to eight yachts a year. Galactica Star (2013, 65 m) was Heesen's first fast displacement yacht, Alive (2014) the first yacht in the world to harness a Hull Vane, and the 70-metre Galactica Super Nova (2016) its largest yacht so far, the year a new 85-metre dry dock opened. Home (2017) introduced a cleaner, quieter hybrid solution, and for its 40th anniversary in 2018 the yard announced the 80-metre Project Cosmos, with a top speed of 30 knots. On 7 April 2025 Heesen announced its full acquisition by the Dutch entrepreneur and investor Laurens Last.
