Design Brief & Intent
The core mission of the Explocat 52 is to allow short-handed crews to safely explore remote, high-latitude regions and debris-strewn tropical waters alike. To achieve this, Garcia constructed the hull and deck structure entirely from marine-grade 5083 H111 aluminum. This material provides exceptional resistance to puncture and fatigue, meaning the vessel can survive impacts with growlers, shipping containers, or uncharted reefs that would compromise a conventional composite hull. To save weight aloft and optimize insulation, Garcia paired this metal platform with a lightweight fiberglass composite coachroof and hardtop bimini.
Inside, Franck Darnet engineered an interior that departs from the sparse, clinical aesthetics often found in performance catamarans. The living quarters feature high-quality wood joinery, insulated floors with sandwich foam cores, and durable synthetic stone work surfaces in the galley. Recognizing that cold climates cause severe interior condensation, the saloon is completely insulated and fitted with double-glazed glass windows with integrated demisters. Standing headroom is a generous 2.05 meters throughout, creating an airy, comfortable sanctuary where the crew can seek refuge from the elements.
Variations & Configurations
The Explocat 52 is semi-custom, allowing buyers to select a layout that matches their specific crew requirements. The standard Owner’s configuration turns the entire starboard hull into a private suite, boasting a large aft stateroom, central storage, and an expansive head with a separate shower stall forward. The Family or Guest configuration divides each hull into two double cabins, accommodating up to eight guests. Some owners utilize the forward port or starboard cabins as dedicated utility rooms to house large laundry facilities, tools, or additional deep-freeze storage.
While the rig is typically configured with an aluminum mast, a high-performance carbon-fiber spar paired with Kevlar standing rigging is available for owners looking to minimize weight aloft and reduce rolling. The sail plan is highly adaptable, typically featuring a fully battened mainsail, a self-tacking solent jib, and a code zero or gennaker flown from a robust bowsprit.
The defining deck configuration, however, is the innovative pivoting swing helm system. Rather than forcing the owner to choose between the exposure of twin aft helms or the isolation of a bulkhead station, the Explocat 52 features a central steering console on a pendular arm. In favorable weather, the column is locked in the elevated position, giving the helmsperson excellent 360-degree visibility over the coachroof for docking and reef navigation. In heavy seas or freezing temperatures, the console swings down, permitting safe, warm operation sheltered under the hardtop bimini and behind the cockpit enclosure.
Sailing Performance & Handling
With a light-ship displacement of 41,005 pounds, the Explocat 52 is heavily constructed compared to carbon-fiber racing catamarans. However, its sailing ratios reflect a highly capable passage maker. A displacement-to-length ratio of 135.99 places it firmly in the light-to-moderate displacement category for cruising multihulls, indicating that the boat carries its momentum efficiently through a seaway. This is balanced by a powerful sail area-to-displacement ratio of 24.18, which ensures the hulls can easily be driven in light airs when flying downwind sails. Long-range cruisers report that the vessel comfortably maintains double-digit speeds, easily averaging 220 to 250 nautical miles per day in moderate trade winds.
A comfort ratio of 15.06 is impressively high for a catamaran, indicating soft, predictable motion rather than the quick, jerky acceleration and deceleration characteristic of ultra-lightweight multihulls. This is enhanced by a bridgedeck clearance of 85 centimeters. This deep clearance prevents the exhausting bridgedeck slamming that often plagues production catamarans in head seas. A capsize screening formula of 3.12 demonstrates the inherent structural stability of its wide 27.88-foot beam. Rather than using deep, vulnerable daggerboards, the Explocat 52 utilizes low-aspect-ratio twin fixed keels. While this limits the boat’s ability to point as high upwind as a daggerboard-equipped performance catamaran, it offers maximum structural safety, protects the rudders and sail drives, and allows the boat to be safely beached for maintenance in remote areas.
Known Challenges & Triage
As an aluminum cruising yacht, the Explocat 52 is immune to fiberglass issues like osmotic blistering, deck coring rot, and structural gelcoat cracking. However, managing an aluminum structure requires strict adherence to preventative maintenance protocols:
- Galvanic Corrosion and Stray Current: The primary technical threat to the Explocat 52 is electrolysis. The vessel features a complex, fully isolated dual-pole electrical system. Owners must conduct regular hull leak tests using the onboard monitoring system to ensure that no positive or negative current is grounded to the aluminum. Additionally, any aftermarket equipment installations require meticulous isolation; stainless steel fasteners or brass fittings must never make direct contact with the aluminum plate without non-conductive barriers, such as Tef-Gel or nylon washers.
- Helm Visibility Blind Spots: While the pendulum helm is a triumph of all-weather design, when locked in its lower position, the massive, insulated coachroof creates a notable blind spot on the opposite bow. When maneuvering in tight marinas or navigating crowded waterways, the skipper must remain vigilant and frequently step away from the wheel or rely on a spotter.
- Weight Sensitivity: Although the hulls are designed to carry the significant payload required for blue-water passages, the boat remains a catamaran and is sensitive to overloading. Adding excessive cruising gear, heavy tenders, and massive high-latitude provisions will lower the bridgedeck clearance and noticeably degrade light-wind performance and upwind pointing capability.
Modernization & Upgrades
While the Explocat 52 is relatively young, owners preparing for extreme off-grid expeditions frequently invest in key system upgrades:
- Advanced Solar and Lithium Integration: Due to the massive surface area of the hardtop bimini, owners routinely upgrade the factory solar array to high-output solar panels. When integrated with a large lithium iron phosphate (LiFePO4) house battery bank, this provides enough energy storage to run high-load appliances—such as electric induction cooktops, watermakers, and washing machines—independently, eliminating the daily need for a diesel generator.
- Redundant Navigation and Autopilots: Given the remote destinations this model is designed to tackle, veteran owners often install complete, dual-redundant autopilot systems with independent hydraulic rams, course computers, and drive units, allowing for immediate failover in mid-ocean.
- Hydronic Heating Redundancy: For high-latitude cruising, the standard insulation is often paired with an upgraded central diesel-fired hydronic heating system. Circulating silent, even heat through radiators in both hulls, this setup is highly efficient and keeps the interior comfortable even when sailing through pack ice.
Market Snapshot & Economics
Because the Explocat 52 is built to order in limited numbers, pre-owned examples are exceedingly scarce on the global brokerage market. Consequently, they command a significant price premium, trading at a level far above mass-production fiberglass catamarans of similar length. The purchasing demographic typically consists of highly experienced, well-capitalized sailors specifically planning long-range, multi-year expeditions or high-latitude adventures. The refit economics reflect a high-end vessel; because of its semi-custom nature and complex systems (including dual-engine setups, hydronic heating, and high-latitude insulation), maintaining or upgrading an Explocat 52 demands specialized marine technicians who understand aluminum yacht construction.
The Verdict
The Garcia Explocat 52 is a masterfully engineered, uncompromising expedition multihull. For sailors whose goals involve crossing oceans to remote, challenging coordinates, its structural rigidity and safety margins are virtually unmatched in the catamaran market. However, for those planning simple, warm-water coastal hops or casual weekend cruising, the heavy-duty engineering, complex electrical maintenance, and steep acquisition cost may represent more complexity and investment than their sailing program requires.
