About the NAUTICAT 331
Deep draft, 4.25'/1.6m.
The Nauticat 331 is a robust, heavy-displacement ketch designed for serious cruising, built by Siltala Yachts in Finland starting in 1997. With a displacement of 18739.0 lb and a comfort ratio of 39.3, this vessel prioritizes stability and seakeeping over speed, reflecting its origins as a safe, offshore-capable cruiser.
- Best for:
- This boat is ideally suited for experienced coastal and offshore cruisers who value a stable, dry ride and are comfortable with the maintenance demands of a heavy, fin-keel ketch. It appeals to those seeking a proven, safe platform for long-distance travel rather than high-performance racing.
- Bluewater capability:
- With a low capsize ratio of 1.68 and a high displacement-to-length ratio of 372.64, the Nauticat 331 is inherently stable and well-suited for bluewater passages, provided the structural integrity of the keel and rudder is verified.
- Comparables:
- Comparable vessels include the Hallberg-Rassy 33 and the Hallberg-Rassy 36, which share similar heavy displacement, ketch rigging, and a reputation for safe offshore handling. The Nauticat 331 also compares to the earlier Nauticat 330, offering a similar layout with updated systems and a slightly different hull form.
