1985–present · built by Ta Yang Yacht Building Co.
Heavy-displacement offshore cruising cutter. Opened public sources describe a fin-keel / skeg-rudder underbody rather than a full keel. Built for shorthanded long-distance passagemaking with full liveaboard amenity and Taiwan-build joinery. Architecturally in the same family as the Tayana 37 and other Ta Yang offshore cruisers (heavy-glass, teak-clad interior).
This is a general read on the Tayana 42 class — informed
background, not a verdict on any individual boat. Condition, refit history,
and how a particular hull was sailed and stored matter far more than class
reputation. Use it to know what to look for; for a read on a specific
listing, run a free FairKeel report on that boat.
Fin-keel / skeg-rudder underbody — combines seakindly motion with better windward performance than a true full-keel. Strong offshore design credentials.
Cutter rig design supports progressive shortening — single-hand- able rig management in increasing wind. Ketch variants give additional sail-plan flexibility.
Same builder (Ta Yang) and same heavy-glass + encapsulated-lead construction tradition as the well-regarded Tayana 37 and Mason 43 — proven offshore class.
Known trade-offs
Below-WL access for through-hull replacement requires cabin sole or settee removal on most hulls. Drives up labor multiplier (1.5-2.0×) for any below-WL work — same pattern as Mason 43.
Teak deck (where fitted) is a major future cost item. A 30+ year Tayana 42 with original teak deck should be priced as if re-decking is on the horizon.
Interior teak joinery is dark and beautiful but absorbs moisture if not actively ventilated. Liveaboard-mode condensation is a real maintenance dimension.
Age-related quirks to expect
Cutter rig vs. ketch rig — confirm which before assessing rig service costs; ketch adds a second mast + rigging setMediumall (rig choice at order)
Teak deck (where fitted) reaching end-of-life by year 30-40 — common Ta Yang specHighhulls fitted with teak decks
Original aluminum or black-iron fuel tanks — corrosion-prone with age, replacement is intrusive on a Taiwan-built interiorMedium1985+
Original Yanmar 4JH-series or Perkins 4-108 — many hulls now on second engineMedium1985+
Original bronze fittings now at 25-40 years. Replacement cluster can be non-trivial on a heavy Ta Yang hull — cabin sole removal often required for access to the deeper bilge fittings. Same labor multiplier pattern as the Mason 43 and Tayana 37.
Original wire + tangs typically due at 25-30 years. Chainplates on Ta Yang-built hulls are bolted through teak-clad bulkheads — leak paths around chainplates often hidden behind joinery. Mast is keel-stepped, so mast-step bilge water history matters.
Teak deck on a 30+ year hull is approaching end-of-life. Look for seam separation, teak plug loss, screw-head exposure, and most importantly underlying deck-core moisture caused by long-term teak-screw leak paths. A failing teak deck can mask a failing glass deck underneath.
Heavy interior teak absorbs moisture if not actively ventilated. Long-term liveaboard use without active dehumidification produces mildew + slow softening of joinery glue lines. Check for staining, especially around hull-side and behind cabinetry.
How it fits your plans
Offshore
Designed for it. Heavy-displacement Bob Perry hull, cutter rig (progressive shortening), full-skeg rudder — credible Pacific / Atlantic / circumnavigation platform in the Ta Yang offshore tradition.
Coastal
Overbuilt for coastal work but a forgiving platform. Slower than fin-keel boats of the same LOA; not a coastal racer.
Liveaboard
Excellent. Generous storage, large tankage, teak-clad interior, aft-cabin layouts common. Below-WL access challenging for DIY maintenance (same as Mason 43 / Tayana 37).
