Designed by Ted Irwin and first launched in 1976, this 30-footer represents solid American production boat building from Irwin Yachts' Florida facility. With her moderate displacement of 9,200 pounds and generous beam of just over 10 feet, she offers the interior space and stability that made her popular among coastal cruisers during the late 1970s and early 1980s. The masthead sloop rig and 474 square feet of sail area provide adequate power for relaxed sailing, while the fin keel with rudder mounted on a protective skeg offers a good balance of performance and directional stability. Her comfort ratio of 23.25 places her in the moderate range, suggesting she'll provide reasonably comfortable motion in seaway conditions typical of coastal cruising. Built with fiberglass construction typical of the era, the Irwin 30 was designed primarily for the recreational sailing market, emphasizing livability over racing performance. Her hull speed of nearly 7 knots and capsize screening value of 1.94 indicate she's best suited for protected waters and coastal passages rather than offshore voyaging. The substantial ballast-to-displacement ratio of nearly 45 percent contributes to her stability and sailing characteristics, making her an approachable choice for intermediate sailors seeking weekend cruising capability.
