Notes

Grampians most popular model and one the most successful boats of this size built in Canada. A keel/cb version was also produced in small numbers. Rarer still is a raised deck version, called the DISCOVERY 7.9, introduced in 1979.
Grampian offered a Palmer (gas) inboard as an option.
Displacement and ballast shown here are as stated for keel version on introductory brochure.
