The story
Harry Hallberg founded his yard in 1943, and in 1965 Christoph Rassy founded a yard, in the premises recently vacated by Hallberg. Harry Hallberg's most distinguished contribution was his understanding of the advantages of using GRP and to build boats in a series. Hallberg-Rassy was formed when Rassy purchased the Hallberg yard after Harry Halberg's retirement in 1972. Since 1989 all boats have been designed by the Argentinian engineer and yacht designer Germán Frers. To date, more than 9,400 yachts have been completed by the yard. The company is owned by the Rassy family, and is managed by Magnus Rassy.
