The Irwin 40 Citation is a classic 1978 design by Ted Irwin, built by Irwin Yachts (USA). While the exact build count is unknown, this single-year production run represents a specific iteration of the popular Irwin 40 line, characterized by its 40.83 ft LOA and 16890.0 lb displacement.
- Best for:
- This boat suits coastal cruisers and weekend sailors who prioritize a comfortable, stable ride over high-performance racing metrics. Its moderate sail area-to-displacement ratio of 18.0 and comfort ratio of 27.47 indicate a vessel designed for balanced, manageable handling rather than speed.
- Bluewater capability:
- With a displacement of 16890.0 lb and a low capsize ratio of 1.9, the Citation is well-suited for offshore passages, offering significant stability and safety margins in heavy weather.
- Comparables:
- Comparable boats include the Cal 40 and O'Day 40, which share similar dimensions and a focus on comfortable cruising. These vessels are comparable due to their similar displacement ranges and masthead sloop rigs, offering a similar balance of interior volume and offshore capability.
