About the IRWIN 41
Keel/CB: BD: 10.08'/3.07m BU: 4.5'/1.37m
The Irwin 41 is a robust, heavy-displacement ketch designed by Ted Irwin and built by Irwin Yachts (USA) in 1982. With a displacement of 25000.0 lb and a comfort ratio of 32.61, this vessel is engineered for stability and seakeeping, though the exact number of hulls built is unknown.
- Best for:
- This boat is best suited for experienced coastal cruisers and those seeking a stable, comfortable platform for extended offshore passages, given its heavy displacement and ketch rig configuration.
- Bluewater capability:
- With a capsize ratio of 1.85 and a displacement of 25000.0 lb, the Irwin 41 demonstrates strong offshore suitability and resistance to capsizing in heavy weather.
- Comparables:
- Comparable vessels include other heavy-displacement ketches from the early 1980s such as the Tartan 42 or O'Day 42, which share similar beam dimensions and cruising-oriented hull forms.
