The Piana 30 is a distinctive performance-oriented trimaran produced by the French shipyard Naval Force 3, based in the maritime center of La Rochelle. Designed by the naval architect Philippe de Piana, this 30-foot multihull was conceived during the late 1980s and early 1990s, a period when French boatbuilders were aggressively pushing the boundaries of transportable multihull design. Built using composite materials—primarily polyester and glass fiber—the Piana 30 reflects the shipyard’s specialty in "original multihulls" that prioritize speed and adaptability. While Naval Force 3 is perhaps better known for its larger Tropic series and the Challenge 30 trimarans, the Piana 30 occupies a unique niche as a refined, folding-arm cruiser that bridges the gap between a racing multihull and a weekend coastal cruiser.

Sailing Performance & Handling
Under sail, the Piana 30 is characterized by its high power-to-weight ratio and the inherent stability of its trimaran platform. With a beam that extends to approximately 6.80 meters (over 22 feet) when deployed, the boat provides a massive righting moment without the need for a heavy keel. This allows for a significantly lower displacement—roughly 1,800 kg—compared to monohulls of similar length. Consequently, the Piana 30 reaches planing speeds quickly in moderate breezes and exhibits the "nervous," responsive handling typical of La Rochelle-built performance boats.
The handling is noted for being "stiff" and upright, which reduces fatigue for the crew during long reaches. The tracking is generally excellent due to the deep central hull and the buoyancy of the outriggers (amas), which are designed to resist burying the nose when pressed hard. Unlike many catamarans of the era, the Piana 30 offers better feedback through the tiller, allowing the helmsman to feel the boat’s balance. The folding arm system, while primarily a logistical feature, does not compromise the structural rigidity of the vessel under load, provided the locking mechanisms are properly maintained.
Interior Comfort & Variations
The interior of the Piana 30 is dictated by the narrow proportions of a trimaran's central hull. While it lacks the expansive "living room" feel of a modern catamaran, it provides functional accommodations for a small crew. The layout typically features a V-berth forward, a central saloon with two settee berths, and a compact galley area. Headroom is functional but limited compared to contemporary 30-foot monohulls, reflecting its focus on aerodynamic efficiency and low centers of gravity.
Materials used in the interior are straightforward and weight-conscious, often utilizing molded composite surfaces with wood accents to save weight. One of the primary variations in this model line involves the customization of the nav station and galley, as Naval Force 3 often worked closely with owners to tailor the interior to their specific cruising needs. The Piana 30 is frequently compared to its siblings, the Challenge 30 and Challenge 30.2, which utilized similar hull forms but differed in their deck molds and folding mechanisms. While the Challenge series was often more utilitarian, the Piana 30 was marketed with a slightly higher focus on refined finish and coastal cruising comforts.
Known Issues & Buyer’s Checklist
Prospective buyers of a Piana 30 should focus their inspection on the specific complexities of the trimaran architecture and the construction methods of the 1990s.
- Folding Mechanisms: The most critical area for inspection is the hinge points and locking bolts of the folding arms. Any play in these joints can lead to structural stress under sail. Owners on French multihull forums have noted that bushings and stainless steel pins may require replacement to ensure the arms remain "rock solid" when deployed.
- Ama Buoyancy and Core: As with many composite boats from this era, the outriggers (amas) should be checked for moisture ingress. Because these hulls are often dragged onto beaches or endure high-impact slamming in heavy seas, the laminate and any core material should be sounded for delamination.
- Mast Step and Compression: The central hull carries significant compression loads from the rig. Inspect the area around the mast step and the internal bulkheads for signs of spider cracking or compression settling, which can occur if the rig has been over-tensioned for racing.
- Trampolines: The netting between the hulls is a safety-critical component. Check for UV degradation and the integrity of the lacing eyes on both the central hull and the outriggers.
Community & Resources
The legacy of Naval Force 3 is currently maintained by the Atlantic Boatyard in La Rochelle, which took over the shipyard's assets and expertise following its liquidation. While there is no longer a dedicated factory support line for the Piana 30, technical knowledge is often shared through French multihull associations and regional sailing clubs in the Charente-Maritime region. Owners often look toward the broader "Multihulls in France" community for technical advice on folding-arm maintenance and sail plans.
The Verdict
The Piana 30 remains a sought-after vessel for sailors who demand high-speed coastal performance and the ability to access shallow anchorages or narrow slips through its folding system.
Pros:
- Exceptional Speed: Capable of outperforming much larger monohulls, especially on a reach.
- Transportability: The folding beam allows for easier winter storage and access to standard marina berths.
- Shallow Draft: Ideal for exploring tidal areas and "drying out" on level sands.
Cons:
- Limited Interior Volume: The narrow central hull offers less living space than catamarans or monohulls of the same length.
- Maintenance Intensity: The folding mechanisms and trampolines require more diligent upkeep than a fixed-keel boat.
- Market Rarity: Finding a well-maintained Piana 30 outside of the French market can be a significant challenge.
