ACHILLES 9M

About the ACHILLES 9M

Designed by Chris Butler and built by Butler Mouldings Ltd. (UK) between 1975 and 1984, the Achilles 9M is a compact cruiser with a production run of exactly 100 hulls. This data-driven synthesis reflects owner reports and market listings, noting that the boat is a 29.83 ft masthead sloop with a displacement of 7000.0 lb.

Best for:

The Achilles 9M suits coastal cruisers and weekend sailors who prioritize a manageable 29.83 ft LOA and a comfortable 9.0 ft beam for interior space. Its moderate D/L ratio of 190.25 and Comfort ratio of 21.67 indicate it is best suited for protected waters rather than heavy offshore passage-making.

Bluewater capability:

With a Capsize ratio of 1.88 and a displacement of 7000.0 lb, the Achilles 9M has moderate offshore potential but is primarily designed for coastal cruising. Owners report successful bluewater use, but the relatively light ballast of 2998.1 lb suggests caution in extreme conditions.

Comparables:

Comparable boats include the Hallberg-Rassy 31 and the Tartan 31, which share similar beam dimensions and displacement ranges from the late 1970s. These vessels offer similar cabin layouts and performance characteristics for owners seeking a robust, fin-keel sloop of this era.
