About the MOTTLE 33
Later the molds went to Naut Yachts. (NAUT 33)
Designed by Joe Adams and built by George Mottle in Australia, the Mottle 33 is a robust Australian cruiser with a production run of 125 hulls completed in 1975. Owner reports highlight its solid construction but emphasize critical maintenance needs, particularly regarding deck core integrity and structural rot.
- Best for:
- This boat suits experienced coastal cruisers and those seeking a sturdy, traditional Australian-built vessel who are prepared to undertake significant structural repairs and maintenance.
- Bluewater capability:
- With a displacement of 9200.0 lb and a capsize ratio of 2.06, the Mottle 33 possesses the heavy displacement and stable hull form necessary for offshore passages, provided critical structural defects are addressed.
- Comparables:
- Comparable to other 1970s Australian fin-keel sloops like the O'Day 32 or early Beneteau models due to similar displacement and era, though the Mottle is distinct for its specific Australian build quality and Joe Adams design.
