About the IRWIN 28
One of Irwin's more popular models that underwent a number of changes over a long production run. Also available with a keel/cb. Draft- BD:7.25'/BU:3.0'
The Irwin 28 is a classic coastal cruiser designed by Ted Irwin and built by Irwin Yachts (USA) in 1970, with an unknown total hull production count. This single-year production run represents a specific snapshot of early 1970s American boatbuilding, characterized by a masthead sloop rig and a displacement of 7900.0 lb.
- Best for:
- This boat is best suited for coastal cruisers and weekend sailors who prioritize a comfortable, stable ride over high-performance racing metrics. Its moderate comfort ratio of 31.67 and manageable size make it ideal for couples or small families seeking a low-maintenance, trailerable or easily moored vessel.
- Bluewater capability:
- With a capsize ratio of 1.61 and a displacement of 7900.0 lb, the Irwin 28 is generally considered suitable for protected coastal waters and short offshore passages rather than extended bluewater voyaging. Its fin keel and moderate ballast ratio provide adequate stability for coastal cruising but lack the heavy displacement typically preferred for serious offshore passage-making.
- Comparables:
- Comparable vessels from this era include the Pearson 28 and O'Day 28, which share similar dimensions and a focus on family cruising comfort. These boats are comparable due to their similar beam of 8.0 ft and displacement ranges, offering a balance of interior volume and manageable handling.
