About the IRWIN 1/2 TON
A shoal draft, fixed keel version was also available. Draft: 5.5'.
The Irwin 1/2 Ton is a classic racer-cruiser designed by Ted Irwin and built by Irwin Yacht & Marine Corporation (USA) in 1976. With a hull count listed as ?, this 32.0 ft LOA vessel represents a specific era of American yacht building focused on performance within the Half Ton Rule.
- Best for:
- This boat suits experienced sailors seeking a performance-oriented coastal cruiser or racer who can manage the maintenance demands of a 1970s fiberglass hull. Its 7300.0 lb displacement and 16.63 SA/D ratio indicate it is best for those who prioritize sailing dynamics over heavy bluewater comfort.
- Bluewater capability:
- With a capsize ratio of 2.12 and a comfort ratio of 19.04, the Irwin 1/2 Ton is primarily a coastal cruiser with limited offshore capability due to its relatively light 7300.0 lb displacement and narrow 24.42 ft LWL.
- Comparables:
- Comparable boats include other Half Ton Rule racers from the mid-1970s such as the O'Day 32 or Pearson 323, which share similar dimensions and racing pedigrees. These vessels are comparable because they were all designed to optimize performance within the same international racing handicap system.
