About the IRWIN 30
Keel/CB draft: BU:4.3' BD: 8.3'
The Irwin 30 is a classic American cruiser designed by Ted Irwin and built by Irwin Yachts (USA) in 1976. With a displacement of 9200.0 lb and a comfort ratio of 23.25, it offers a stable, heavy-displacement platform that prioritizes seakeeping over raw speed.
- Best for:
- This boat suits coastal cruisers and those seeking a comfortable, stable day-sailer or short-range cruiser who value interior volume and ease of handling over high-performance racing metrics.
- Bluewater capability:
- With a capsize ratio of 1.94 and a displacement of 9200.0 lb, the Irwin 30 is generally considered suitable for coastal and protected offshore cruising, though its single-year production run and age require careful structural assessment for extended bluewater passages.
- Comparables:
- Comparable boats include the Cal 30 and O'Day 302, which share similar beam dimensions and heavy-displacement characteristics from the mid-1970s, offering comparable interior layouts and cruising comfort.
