About the Irwin 41 Citation Sailboat

Designed by Ted Irwin and built by Irwin Yachts beginning in 1982, this 41-foot sailboat represents a relatively rare find with only four hulls ever constructed. The Citation combines performance-oriented design elements with cruising practicality, featuring a fin keel with spade rudder configuration that delivers responsive handling and good upwind performance. With a displacement of 17,500 pounds and substantial ballast ratio courtesy of its 9,500-pound keel, the Citation offers reassuring stability for coastal and offshore passages. The masthead sloop rig carries 787 square feet of sail area, providing a sail-area-to-displacement ratio of 18.75 that strikes a balance between spirited performance and manageable sail handling. Her comfort ratio of 24.9 suggests motion characteristics well-suited for extended cruising, while the capsize screening value of 2.01 indicates good stability margins for offshore work. The fiberglass construction and moderate beam of just over 13 feet make this boat well-suited for sailors seeking a performance cruiser capable of both coastal exploration and longer passages. Her 7.73-knot hull speed potential and 30-horsepower auxiliary engine provide reliable progress under both sail and power, making the Citation an intriguing choice for experienced sailors who appreciate exclusive designs with proven seaworthiness.

Known Issues View all 10 issues →
High
The deck-to-hull joint on Irwin boats of this period was often poorly bonded and fastened, relying heavily on sealant. Water intrusion at this joint is a chronic problem, leading to delamination of the deck core (typically balsa or foam) and soft spots across the deck.
High
Balsa-cored decks on Irwin 41s are highly prone to water saturation, particularly around any deck hardware where bedding has failed. Widespread soft deck areas are common on boats of this age and should be thoroughly sounded during survey.
High
The fin keel attachment on Irwin 41s has been reported to suffer from inadequate keel-to-hull bonding and keel bolt corrosion. The sump area should be carefully inspected for rust weeping, movement, or cracking of the tabbing around the keel stub.
