About the IRWIN 44
The Irwin 44 is a robust cruising sloop designed by John R. Van Ost and built by Irwin Yachts (USA) in 1987. With a displacement of 25000.0 lb and a comfort ratio of 32.29, this vessel is engineered for stability and seakeeping, though the exact total hulls built is unknown.
- Best for:
- This boat is best suited for serious coastal and offshore cruisers who prioritize a heavy, stable platform over high-speed performance. Its substantial displacement and fin keel make it ideal for couples or families seeking a comfortable, safe passage-making vessel.
- Bluewater capability:
- With a capsize ratio of 1.83 and a D/L ratio of 245.91, the Irwin 44 demonstrates strong offshore suitability and resistance to capsizing in heavy weather.
- Comparables:
- Comparable vessels include the Cal 40 and O'Day 40, which share similar production eras and heavy-displacement cruising philosophies. These boats offer similar interior volumes and offshore capabilities, making them direct competitors in the used market.
