Designed by Hunt & Associates and built by O'Day Corp. (USA) from 1977–1984, the O'Day 30 is a robust coastal cruiser with 356 hulls produced. Its design emphasizes comfort and stability, featuring a displacement of 10500.0 lb and a comfort ratio of 25.64, making it a popular choice for weekend cruising and light offshore passages.
- Best for:
- This boat is best suited for coastal cruisers and families seeking a stable, comfortable platform for weekend getaways, as well as single-handers who benefit from its manageable size and responsive handling. It is less ideal for serious bluewater expeditions due to its moderate displacement and fin keel configuration.
- Bluewater capability:
- With a displacement of 10500.0 lb, a capsize ratio of 1.97, and a fin keel, the O'Day 30 is capable of protected coastal passages but lacks the heavy displacement and full keel stability typically preferred for extended bluewater cruising.
- Comparables:
- Comparable boats include the Cal 30 and the Hunter 30, which share similar dimensions, masthead sloop rigs, and a focus on interior volume and ease of handling. These models also target the same market of recreational cruisers looking for a balance between performance and comfort in the late 1970s and early 1980s.
