About the ALPA A9
Dimensions from original builders brochure.
The Alpa A9 is a 29.82 ft masthead sloop designed by Illingworth & Associates and built by Alpa (ITA) between 1967 and 1970. With a displacement of 8598.0 lb and a comfort ratio of 29.87, this vessel represents a classic Italian cruiser from the late 1960s, though the exact number of hulls built remains unverified in available data.
- Best for:
- This boat is best suited for coastal cruisers and weekend sailors who prioritize a comfortable motion and manageable size, given its moderate beam of 8.86 ft and single-handed friendly dimensions.
- Bluewater capability:
- With a capsize ratio of 1.73 and a D/L ratio of 361.47, the Alpa A9 offers moderate offshore stability, making it suitable for protected coastal passages but less ideal for heavy oceanic bluewater voyaging compared to heavier displacement designs.
- Comparables:
- Comparable boats include the Nauticat 31 and the Tartan 31, as they share similar production eras, displacement ranges, and the Illingworth & Associates design philosophy of balanced performance and comfort.
