About the DISCOVERY 7.9 (GRAMPIAN)
Based on the GRAMPIAN 26 but with a raised deck and coachroof. Very few built.
The Discovery 7.9 (Grampian) is a 26.0 ft masthead sloop designed by Alex McGruer and built by Grampian Marine Ltd. (CAN) between 1975 and 1977. With a displacement of 5100.0 lb and a comfort ratio of 20.32, this vessel represents a compact, moderately heavy cruising platform from the mid-1970s Canadian market.
- Best for:
- This boat is best suited for coastal cruisers and weekend sailors who prioritize a manageable 26.0 ft LOA with a stable, comfortable motion over high-performance racing metrics.
- Bluewater capability:
- With a capsize ratio of 1.94 and a displacement of 5100.0 lb, the boat offers reasonable stability for protected offshore passages, though its 26.0 ft LOA and fin keel configuration suggest it is primarily designed for coastal rather than extended bluewater use.
- Comparables:
- Comparable vessels include other 26-foot Canadian production sloops from the mid-1970s, such as the Pearson 26 or O'Day 26, which share similar displacement ranges and coastal cruising roles.
