Designed by German Frers and built by Hallberg-Rassy, the HR31 is a robust fractional sloop produced from 1992–2009 with a total build count of 356 hulls. It combines a heavy displacement of 9921.0 lb with a comfort ratio of 22.58, reflecting its reputation for solid, safe offshore cruising.
- Best for:
- This boat is ideal for coastal and offshore cruisers who prioritize safety and comfort over high-performance racing, particularly those seeking a proven platform for bluewater passages.
- Bluewater capability:
- With a displacement of 9921.0 lb, a low capsize ratio of 2.02, and a fin keel, the HR31 is well-suited for offshore passages, though owners report significant structural concerns regarding the keel sump that must be addressed before long-range cruising.
- Comparables:
- Comparable boats include the Hallberg-Rassy 32 and 36, which share similar German Frers design philosophies and heavy-displacement characteristics, as well as the Nautor's Swan 42 for its era-defining cruising performance.
