About the NAUTICAT 33
Thee NAUTICAT 33 was the first boat produced by Siltala and one of the most successful. In 1977 the raised aft deck was offered as an option and a number of other changes were made to this design during it's production run. An updated model, the NAUTICAT 331, was introduced in 1997.
Designed by W. Aarnipalo and built by Siltala Yachts (FIN) from 1967–1996, the Nauticat 33 is a robust masthead ketch with 1160 hulls produced. Its heavy displacement of 17250.0 lb and full/long keel provide exceptional stability and seakeeping, though owners frequently report significant maintenance challenges regarding the deck core and rudder systems.
- Best for:
- This vessel is best suited for experienced coastal cruisers and conservative bluewater sailors who prioritize safety and comfort over speed, particularly those willing to undertake substantial mechanical and structural maintenance.
- Bluewater capability:
- With a D/L ratio of 344.49 and a capsize ratio of 1.65, the Nauticat 33 is inherently stable and well-suited for offshore passages, provided the critical rudder and deck core issues are addressed.
- Comparables:
- Comparable to the Tartan 34 and Valiant 40 due to similar heavy-displacement, full-keel designs from the same era that prioritize motion comfort and offshore capability over planing performance.
