The Discovery 7.9 is a Canadian sailboat, that was designed by Alex McGruer and first built in 1975.[1][2]

The Discovery 7.9 is a development of the Grampian 26.[1][3]

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.[1][4]

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.[4]
