Design and Construction
The defining structural story is the Strongall aluminum hull, a method META developed and patented in 1977 for assembling thick pre-stressed aluminum sheets into a self-supporting shell. On the JPB 52 that Strongall aluminum hull guarantees great resistance to impacts and exceptional longevity, a construction posture suited to a boat rated Category A offshore and intended to run aground at will. The integral centerboard is the key to that brief: with a shallow version drawing just 1.10 meters and a deeper variant at 3.15 meters, the centerboard lets the yacht access confined anchorages and remote shores while retaining seaworthy performance when lowered. Twin rudders and a lifting-keel ballast of 5 tonnes complete a profile built for comfort and safety without fault in open water.
Rig and Performance
Above the deck, the JPB 52 carries 147 square meters of upwind sail area, split between a 68-square-meter mainsail and a 79-square-meter genoa. Those figures, on a 17-tonne hull with a 14.50-meter waterline, describe a voyager tuned for passage-making rather than raw speed, yet the centerboard's flexibility means she can be lightened for thin water or ballasted down for offshore legs. The design premise, as the builder's specification and period editorial both affirm, is a boat made for the open sea whose layout and structure exist to remove apprehension from remote cruising.
Accommodations
Inside, the JPB 52 is a sailing boat with large interior spaces and two distinct living zones. A central saloon holds the kitchen and chart table, while a second large saloon aft adds a bar and numerous sofas, with two single berths tucked into that rear lounge. Sleeping capacity runs to 10 or 11 berths across three cabins: a private double for the owner, one with bunk beds, and a single berth cabin, served by two heads. The cockpit reinforces the passage ethos with multiple access points to the boat at the aft and front, easing movement under way and at anchor. META Yachts also offers custom layouts built in their Port Saint-Louis du Rhône workshop, so individual hulls may diverge from the standard three-cabin plan.
Refits and Ownership
Because META Yachts describes none of its JPB designs as set in stone and invites owner suggestions, the used fleet likely shows variation in joinery, systems, and space planning. The standard engine is a Nanni diesel N4.65 SD producing 65 cv at 2700 rpm, backed by 800 liters of fuel and 640 liters of water — generous tankage for extended autonomy. A JPB 52 has been documented offering Mediterranean cruises around Corsica and Sardinia, a practical illustration of the range the design supports.
The Verdict
The JPB 52 is a serious expedition platform: aluminum Strongall construction, a centerboard that removes drafting worries, and voluminous living spaces wrapped around a Category A offshore rating. Customizability is a genuine strength, but it means no two boats are guaranteed identical below.
Pros
- Strongall aluminum hull with documented impact resistance and longevity
- Integral centerboard enables 1.10 m shallow draft or 3.15 m offshore profile
- Two saloons and 10–11 berths across three cabins with twin cockpit access
- Category A offshore rating with 800 L fuel and 640 L water capacity
Cons
- 17 t displacement limits light-air agility versus lighter cruisers
- Custom-layout tolerance means buyers must verify each hull's actual plan
