1979–present · designed by Robert Harris · 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).
Check this first — the Tayana 42 and the Tayana Vancouver 42 are the SAME BOAT — Robert Harris's Vancouver 42, built by Ta Yang from 1979, and listed under both names. About 200 were built in three configurations that matter more than the name: roughly 130 aft-cockpit (in two different house designs), about 70 centre-cockpit, and five pilothouse. Establish which configuration you are looking at, because the accommodation and the deck are genuinely different boats above the sheer.
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.

What the Tayana 42 is known for
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-ballast construction tradition as the well-regarded Tayana 37 and Mason 43 — proven offshore class. This hull's own ballast is iron, not lead (see architecture.ballast_config).
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
Most boats carry the 50hp Perkins 4-108; some came with a Yanmar 4JHE. Cruising World is direct that these boats "are a bit underpowered" with the Perkins — the reviewers repowered their own with a 75hp turbocharged Yanmar. Unlike some underpowered claims, this one is owner-supported rather than inferred from a spec sheet. Note also that the reported failure mode is corrosion rather than wear.severity: Mediumaffects: 1979 onward (all)
Black-iron fuel tanks rust from the outside in wherever the external paint has chipped. Cruising World names this specifically, and it is the kind of defect that is invisible until the tank is out.severity: Mediumaffects: 1979 onward (all)
Blistering is LESS likely than the era suggests on later boats: isophthalic gelcoat from 1985, and vinylester laminate from 1992. Cruising World reports hull-deck joints and serious blistering have not typically been problems, though some older boats show chainplate corrosion.severity: Lowaffects: pre-1985 hulls carry the most exposure
Cutter rig vs. ketch rig — confirm which before assessing rig service costs; ketch adds a second mast + rigging setseverity: Mediumaffects: all (rig choice at order)
Teak deck (where fitted) reaching end-of-life by year 30-40 — common Ta Yang specseverity: Highaffects: hulls fitted with teak decks
Original aluminum or black-iron fuel tanks — corrosion-prone with age, replacement is intrusive on a Taiwan-built interiorseverity: Mediumaffects: 1985+
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 deck-stepped (2026-05-20 architecture correction, Cruising World) — check the deck-step compression post and partners for moisture, not a bilge mast-step.
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 Robert Harris 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).
This guide is the class. A report is that hull. Paste the
listing you're looking at and FairKeel grades every claim in it against what's
known about the Tayana 42 — where the evidence is thin, the red flags worth
a second look, the costs likely to land in your first season, and whether the
boat suits the plans you describe in a few short questions.

Deep-Dive isn't worth buying. Free, no account, usually a minute or two.
