Irwin 24
Description
The Irwin 24 is a fiberglass masthead sloop designed by naval architect Ted Irwin and built by Irwin Yachts from approximately 1970 to the mid-1970s. As an early entry-level model in Irwin's lineup, it was engineered for affordable coastal and day sailing, targeting novice sailors and small families with its trailerable design, modest performance, and surprisingly spacious interior for a 24-footer. Featuring a fixed fin keel (with rare keel/centerboard options), it's suited for protected waters like bays, lakes, or short coastal runs (e.g., Florida Keys, Chesapeake Bay) but not for blue water due to its light construction and moderate stability. Often described as a "fixed keel version of the Irwin 23," it shares design DNA with that model but offers slightly more interior volume and beam for comfort. Approximately 100-150 hulls were produced.
