Design and Construction
The Valiant 40's underbody is the heart of its character. The cut-away forefoot, modified fin keel with external lead, and skeg-hung rudder reduced wetted surface area without sacrificing directional stability, a configuration that lets the boat track well and maneuver in close quarters. Early keels are slightly longer than later ones, a subtle evolution rather than a redesign. Above the waterline, there is just enough bow flare to keep the deck reasonably dry, and loads of forward buoyancy keep the bow from pearling in a seaway. The hull numbers tell a more complicated story: between hull numbers 120 and 249, resin mixtures were changed to include a fire-retardant additive, and there was a high correlation between that additive and the blisters that later developed. Blisters developed on most — but not all — of the boats produced between 1976 and 1981. Spar-tech in Seattle built most of the rigs.
Rig and Handling
A few early Valiant 40s left the factory with longer booms and end-boom sheeting, a configuration that proved a nuisance bordering on dangerous for the unaware helmsperson during a gybe. The factory responded by introducing a mid-boom traveler with a shorter boom and slightly taller rig, a change that improved cockpit safety and trim control. The cutter rig itself, paired with a conventional windvane and good sails, produces a consistent and comfortable 6.5 to 7.5 knots on a breezy passage. The boat is capable of consistent 165-mile days without demanding a crew willing to expend lots of energy, a passage-making pace that reflects the efficiency of the underbody rather than raw sail area. The cockpit is comfortable and secure, a working space sized for offshore watch-standing rather than dockside lounging.
Accommodations
The interior has remained the same across the production run, which means a used boat from hull 101 and one from hull 159 share the same fundamental plan. A combination aft "stateroom" gives private quarters without consuming the whole stern, while outboard pilot berths and a V-berth forward make for happy cruising on extended voyages. The U-shaped galley with terrific storage sits where a cook can brace against motion, and the traditional main saloon carries either a bulkhead table or a permanent cruising fold-down job depending on the owner's preference. A head with separate shower completes the layout, and cabin headroom over 6 feet runs throughout. The result is a liveaboard-scale interior scaled to the boat's 39 feet 11 inches LOA and 12 feet 4 inches beam rather than inflated by visual tricks.
Known Issues
The dominant documented concern is blistering tied to the fire-retardant resin used between hull numbers 120 and 249. While not every boat in that range blistered, most produced between 1976 and 1981 did, and a buyer should treat any boat in that serial range as a candidate for hull inspection below the waterline. The other known issue is operational rather than structural: early boats with end-boom sheeting require a helmsperson who understands the gybe behavior, and the mid-boom traveler retrofit is the straightforward remedy. Neither issue undermines the model's reputation, but both are specific enough to warrant a surveyor's attention at the relevant hull numbers.
Refits and Ownership
Because the interior never changed, refit energy on the Valiant 40 tends to flow toward rig and systems rather than layout. The mid-boom traveler conversion is the most meaningful handling upgrade for early boats, and the various diesel auxiliaries — rated at 40-hp across the model — have been swapped by owners over decades of use. Fuel and water capacity average 95 and 120 gallons respectively, with a 15-gallon holding tank, figures that support the boat's distance-cruising intent without forcing constant dock stops.
The Verdict
The Valiant 40 is a Perry-designed canoe-stern cruiser whose reduced-wetted-surface underbody and cutter rig deliver dependable passage-making speeds without crew exhaustion. Its fixed interior plan and secure cockpit make it a practical liveaboard, while the documented blister range and early end-boom sheeting quirk are narrow, identifiable caveats rather than systemic flaws.
Pros
- Cut-away forefoot and skeg-hung rudder reduce wetted surface for efficient tracking
- Proven offshore record including first American monohull OSTAR finish (hull 122)
- Stable, unchanged interior with aft stateroom, pilot berths, and separate-shower head
- Consistent 6.5–7.5 knot passages and 165-mile days under cutter rig
Cons
- Blister correlation on hulls 120–249 from fire-retardant resin (1976–1981 build)
- Early end-boom sheeting boats pose gybe risk to unaware helmspeople
