About the NAJA 30
Multi chine hull. Also sold in kit form.
The Naja 30 is a 30.0 ft masthead sloop designed by Sylvestre Langevin and built by A & T Marine Services/Whisstock's Boatyard in 1976. With a displacement of 7200.0 lb and a comfort ratio of 18.53, this vessel represents a specific era of Canadian boatbuilding with a single-year production run.
- Best for:
- This boat suits coastal cruisers and weekend sailors who prioritize a comfortable motion and manageable size over high-performance racing metrics. Its moderate displacement and beam of 10.33 ft make it well-suited for protected waters and short offshore passages.
- Bluewater capability:
- With a capsize ratio of 2.14 and a displacement of 7200.0 lb, the Naja 30 is stable enough for coastal and nearshore cruising but lacks the heavy displacement and proven long-range history required for serious bluewater voyaging.
- Comparables:
- Comparable vessels include other 30-foot Canadian-built cruisers from the mid-1970s, such as the Pearson 303 or O'Day 302, which share similar displacement ranges and cruising-oriented hull forms. These boats offer similar interior volumes and ease of handling for short-handed crews.
