About the CORINTHIAN 28
The Corinthian 28 is a classic Canadian cruiser designed by C. A. Martzoucos and built by Olympic Yachts Ltd. in 1967. With a build count of ?, this single-year production run represents a specific snapshot of late-60s yacht design, characterized by a full keel and masthead sloop rig.
- Best for:
- This boat suits coastal cruisers and weekend sailors who prioritize stability and ease of handling over high-performance racing. Its moderate displacement and full keel make it well-suited for relaxed cruising in protected waters.
- Bluewater capability:
- With a displacement of 6860.0 lb and a capsize ratio of 1.83, the Corinthian 28 offers moderate offshore capability, though its age and single-year production suggest it is better suited for coastal passages than extended bluewater voyages.
- Comparables:
- Comparable boats include other Olympic Yachts models and similar 28-foot full-keel sloops from the late 1960s, such as the Pearson 28 or O'Day 28. These vessels share similar dimensions, displacement characteristics, and a focus on comfort and seaworthiness rather than speed.
