About the IRWIN 25

Designed by Ted Irwin and built by Irwin Yacht & Marine Corp. (USA) from 1969–1976, the Irwin 25 is a classic masthead sloop with a displacement of 5400.0 lb and a beam of 8.0 ft. While the exact hulls built count is unknown, this model represents a significant era of American production yachts known for their robust construction and traditional aesthetics.
- Best for:
- This boat is best suited for coastal cruisers and weekend sailors who prioritize a comfortable, stable ride with a comfort ratio of 23.79 over high-performance racing. Its manageable size and full keel design make it accessible for single-handers or couples seeking a low-maintenance, traditional sailing experience.
- Bluewater capability:
- With a capsize ratio of 1.83 and a displacement of 5400.0 lb, the Irwin 25 is generally considered suitable for protected coastal waters and short offshore passages rather than extended bluewater voyaging.
- Comparables:
- Comparable boats from this era include the Pearson 24 and O'Day 23, which share similar displacement ranges and full-keel, masthead sloop configurations. These vessels offer similar coastal cruising capabilities and traditional layouts, making them direct competitors in the used market.
