Built by Irwin Yachts beginning in 1983, the Citation represents Ted Irwin's approach to creating an affordable coastal cruiser that balances comfort with reasonable sailing performance. This 31-foot masthead sloop features the era's popular fin keel and spade rudder configuration, delivering predictable handling characteristics that appeal to both novice and experienced sailors. With a displacement of 9,300 pounds and moderate sail area of 474 square feet, the Citation prioritizes stability and ease of handling over racing performance. The beam of 11 feet provides generous interior volume, while the 6-foot draft offers good directional stability without limiting access to most coastal anchorages. The comfort ratio of 21.11 reflects the boat's design philosophy, emphasizing livability for extended coastal cruising rather than lightweight performance. The Citation's fiberglass construction and straightforward systems make it an attractive option for sailors seeking a reliable platform for weekend getaways and coastal exploration. While not intended for serious offshore passages, this design handles typical coastal conditions with confidence. The masthead sloop rig keeps sail handling simple, and the spade rudder provides responsive steering. For sailors prioritizing comfort, affordability, and ease of maintenance over cutting-edge performance, the Citation delivers solid value in the competitive 31-foot cruiser market.
