Production
The boat was built by Grampian Marine in Canada between 1975 and 1977, but it is now out of production. Only a small number were completed.{{cite web|url =https://sailboatdata.com/builder/grampian-marine|title = Grampian Marine|accessdate = 9 June 2018|last= Browning| first = Randy |work = sailboatdata.com|year = 2018|archive-url= https://archive.today/20220303141303/https://sailboatdata.com/builder/grampian-marine|archive-date= 3 March 2022|url-status= live}}
After Grampian's end of production the molds were acquired by a new company who built a small number of boats with different window arrangements.
