Valiant 42

1992–2011 · designed by Robert Perry · built by Valiant Yachts

The Valiant 42 was designed by Robert Perry as a dedicated offshore passage-maker, introduced in 1992 as an evolution of the original Valiant 40 hull. The deck mold was updated to offer more interior layout options while the hull form was retained and refined with a more efficient foil-shaped fin keel and taller double-spreader cutter rig. The skeg-hung rudder, canoe stern, and heavy displacement reflect Perry's emphasis on directional stability, self-steering compatibility, and survivability at sea. The boat was sold as a low-volume semi-custom long-distance cruiser and earned its bluewater reputation through owner-driven ocean crossings and circumnavigations.

This is a general read on the Valiant 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.

What the Valiant 42 is known for

Exceptional offshore pedigree — the Valiant 42 has completed numerous bluewater passages and circumnavigations, and the hull form and construction reflect that mission honestly across all 86 hulls built.
Skeg-hung rudder provides reliable steering and redundancy offshore; rudder loss is less catastrophic than a spade-rudder failure and jury-rigging is more tractable.
Keel-stepped, double-spreader cutter rig is structurally conservative — more forgiving of rig loads and easier to support with jury repairs at sea than deck-stepped alternatives.
Low production volume (86 hulls) means strong owner community cohesion and deep documentation base; parts, refit experience, and surveyor familiarity are readily available compared to more obscure bluewater designs.
Robert Perry hull form has a well-documented, predictable motion offshore — the canoe stern and moderate beam reduce hobby-horsing and make long ocean passages more tolerable for crew.

Known trade-offs

Balsa-cored decks are the class's Achilles heel — moisture intrusion is common and expensive to remediate, and the problem is often concealed by cosmetic repairs. Budget for a full moisture survey.
Performance is modest by modern standards — heavy displacement and a conservative sail plan mean slow passages in light air, and the boat will not point as high or accelerate as quickly as contemporary fin-keel designs.
Chainplate and deck-seal failures are a recurring maintenance issue; the geometry concentrates load at deck penetrations that are difficult to keep permanently watertight, requiring periodic re-bedding and inspection.
Interior volume is less than a buyer might expect for a 42-foot boat — the offshore-optimized hull prioritizes seakeeping over beamy accommodation, which disappoints buyers expecting liveaboard spaciousness.
With only 86 hulls built, the used market is thin and examples are geographically scattered; finding a well-maintained hull at fair value requires patience, and refit budgets for older examples can match or exceed market value.

Age-related quirks to expect

Balsa deck core moisture intrusion around hardware penetrations High 1992–2005

Chainplate backing plate corrosion and deck-seal failure High 1992–2011

Standing rigging age — hulls with original or long-interval rod rigging High 1992–2001

Westerbeke diesel service deferred — injectors, heat exchanger, transmission Medium 1992–2005

Skeg attachment and rudder bearing wear on higher-mileage hulls Medium 1992–2011

Gelcoat osmotic blistering on earlier hulls with deferred barrier coat Medium 1992–2000

Systems to check before you buy

Deck core and chainplate areas priority: offshore, coastal, liveaboard

Balsa-cored decks are the class's most common structural liability. Moisture intrusion around chainplates, stanchion bases, and hardware penetrations is common on older hulls. Probe all deck hardware with a moisture meter; any soft spots or chainplate weeping warrants core replacement before offshore use.

Rig and chainplates priority: offshore, coastal, racing

Keel-stepped mast with double-spreader rig is structurally conservative, but chainplate-to-hull attachment and backing plates below deck are a chronic weak point. Look for rust staining on the headliner, crevice corrosion on the plates themselves, and compromised deck seals. Rod rigging over 10 years old should be replaced before any offshore passage.

Engine and drivetrain priority: offshore, liveaboard, coastal

Stock Westerbeke 43hp diesel engines are now 15-30+ years old on most hulls; compression, fuel-injector condition, heat exchanger, and transmission should be surveyed carefully. Some hulls have been repowered — verify repower quality and engine-mount alignment. Budget a repower if the original is in poor health.

Hull-to-keel joint and keel bolts priority: offshore, coastal

Bolt-on external lead keel through-bolted with stainless J-bolts. Inspect the keel-hull joint for cracking, weeping, or rust staining — indicators of bolt corrosion or joint flex. On boats with hard groundings in their history, removal and inspection of keel bolts is prudent before offshore use.

Through-hulls and seacocks priority: offshore, liveaboard, coastal

Older bronze seacocks may be dezincified or seized; Marelon replacements are common on maintained hulls. Count all below-waterline fittings, verify seacock operation under load, and inspect hose condition and clamps. A failed seacock is a sinking event; this is non-negotiable for offshore use.

How it fits your plans

Offshore: One of the most credentialed offshore passage-makers in its size range. The skeg-hung rudder, heavy displacement, and keel-stepped mast make it forgiving and robust in severe conditions. Only 86 were built, making a well-maintained example a genuine bluewater platform — but condition inspection is everything on any hull now 15-30+ years old.
Coastal: Competent coastal cruiser but somewhat slow and heavy relative to modern designs. The extra structure and seakeeping margin are underutilized on coastal passages but do no harm. Excellent choice for coastal cruisers who want offshore capability in reserve.
Liveaboard: Accommodation is practical rather than palatial for a 42-footer — typical of Perry's offshore-first prioritization. Comfortable for a couple; tight for a family. The boat's structural integrity makes it a sound liveaboard platform if maintained.
Weekending: Capable but likely overkill for weekending. The rig and systems demand are higher than a pure coastal boat. Makes sense as a weekender only if offshore or coastal cruising is the eventual goal.
Racing: Not a racing boat. Heavy displacement and conservative sail plan put it well off the pace of modern designs in any rating class. PHRF ratings are possible but competitive results are unlikely.
