About the IRWIN 31 CITATION
Keel/cb version: BU: 4.0' BD: 8.92'. Shallow draft fixed keel: 4.0'
The Irwin 31 Citation is a classic 1983 design by Ted Irwin, built by Irwin Yachts (USA) with a production run limited to that single year. While the exact hull count is unverified, this masthead sloop is characterized by its 31.25 ft LOA, 11.0 ft beam, and 9300.0 lb displacement, offering a balanced blend of performance and comfort with a Comfort ratio of 21.11.
- Best for:
- This boat suits coastal cruisers and weekend racers who value a responsive, well-proportioned sloop with a 17.21 SA/D ratio, rather than heavy bluewater passagemakers.
- Bluewater capability:
- With a Capsize ratio of 2.1 and a D/L ratio of 223.1, the Citation is moderately stable but lacks the heavy displacement and robust construction typically required for serious offshore bluewater voyaging.
- Comparables:
- Comparable boats include the Pearson 303 and O'Day 32, as they share similar 30-foot dimensions, fin keel configurations, and target the same market of affordable, performance-oriented coastal cruising.
