Irwin 41 Sloop
Description
The Irwin 31 Sloop is a fiberglass masthead sloop designed by Ted Irwin and built by Irwin Yachts in St. Petersburg, Florida, from 1967 to approximately 1975. As one of the first models produced by Irwin Yachts after its founding in 1966, the Irwin 31 was designed as an affordable coastal cruiser for families and novice sailors, emphasizing simplicity, a roomy interior for its size, and ease of handling. It predates the later Citation series (e.g., Citation 31) and lacks the performance-oriented features of those models, focusing instead on comfort for weekend sailing or short coastal trips in protected waters like bays, lakes, or nearshore routes (e.g., Florida to Bahamas). Approximately 200-300 hulls were built, making it a relatively rare classic today. It was offered with a fixed fin keel or an optional keel/centerboard for shallow-water versatility.
