Sources disagree on deck construction, number built, last year — left blank rather than guessed.
Pilothouse ketch motorsailer. Mk I (hulls 1-440, pre-1977) had a long shoal keel and wooden wheelhouse; all-GRP Mk II from 1979; fin keel with skeg-hung rudder optional from 1982. Commonly powered by a 90 hp Ford Lehman. Two owners interviewed by Yachting Monthly had fitted bow thrusters. Replaced by the Nauticat 331 in 1997.
Known problems for this model
-
Soft decks under teak (wet core) deck
Surveyors report soft, flexing decks under the teak where water entered through screw holes and rotted a core; some owners say their decks are solid glass, so construction may vary by year (see disputed).yachtingmonthly.com · sailnet.com · forums.ybw.com
-
Mast compression / rotting support bulkhead hull
A surveyor found mast compression on several boats, from under-supported loads or bulkheads rotted by water ingress, with over 10 mm of deck deflection in two cases.yachtingmonthly.com
-
Osmotic blistering hull
Surveyors report many Nauticat 33s with osmosis and wet laminate below the waterline.yachtingmonthly.com
-
Early wooden wheelhouses and leaking windows deck
Pre-1979 boats had wooden wheelhouses that must be checked for rot and leaks; leaking windows on any boat can ruin interior joinery.yachtingmonthly.com
Engines & parts
Ford Lehman 135 / SP135 (2725E) parts: good
Factory standard engine — you entered “Ford Lehman 2725E”
Based on the later Ford 'Dover' 2725E 6.2 L naturally aspirated six (Ford built the Dover series 1982–1994, then Otosan/Dovertech to 2005). Parts are sold by the same Lehman specialists as the 120; American Diesel lists spare-parts sheets and Go2marine stocks cooling parts, heat exchangers and elbows for the 135. Do not assume 120 (2715E) and 135 (2725E) internals interchange.
