Sailing Performance & Handling
The Fastcat 50 is designed for high speed and efficient windward progress, diverging from the "floating apartment" philosophy of many modern production catamarans. According to African Cats, the hull’s narrow entries and lightweight construction allow for speeds frequently exceeding 15 knots, with polars indicating the ability to reach 20 knots in favorable conditions. Unlike many cruising cats that rely on fixed keels, the Fastcat series typically features high-aspect-ratio daggerboards, which significantly improve upwind tracking and reduce leeway.
The boat’s handling is noted for being sensitive and rewarding for experienced sailors. Technical data suggests a high Sail Area/Displacement (SA/D) ratio, which translates to immediate acceleration in light air. Reviewers of the related Fastcat 435 have noted that the helm remains light even at high speeds, though the vessel’s low weight makes it sensitive to over-loading, which can drastically degrade its performance potential. The "Green Motion" retractable drive legs further enhance performance by eliminating the drag of propellers and shafts while under sail.
Interior Comfort & Variations
The interior of the Fastcat 50 reflects its performance-first mandate, utilizing lightweight materials such as foam-cored cabinetry and carbon fiber accents. Most hulls are custom-finished, though the standard layout typically offers three or four ensuite cabins. The saloon is designed with 360-degree visibility and often features a forward-facing navigation station to facilitate long-distance watchkeeping.
Because African Cats emphasizes sustainability, the interior often omits traditional propane systems in favor of induction cooking and LED lighting, powered by a substantial solar array on the coachroof and the electric regeneration system. Variations in the model line include the "World Cruiser" version, which provides more storage and structural reinforcement for circumnavigations, and the "Sports Cruiser," which prioritizes weight reduction.
Known Issues & Buyer’s Checklist
Prospective buyers should approach the Fastcat 50 with a focus on its specialized systems and historical branding controversies. High-signal technical areas for inspection include:
- Electric Propulsion & Battery Maturity: Early "Green Motion" systems were pioneering but complex. Buyers should verify the age and health of the Lithium-Ion battery banks and the mechanical functionality of the retractable drive legs, which require regular maintenance to prevent seizing or leaks.
- Weight Verification: There have been historical debates within the cruising community regarding the builder's "dry weight" claims. It is highly recommended to weigh the boat during a survey to understand the actual remaining payload capacity, as performance suffers significantly if the hulls sit below their designed waterline.
- Hull Provenance: Technical research suggests that at least one "Fastcat 50" hull was reportedly a modified and rebranded St. Francis 48. Buyers should verify the HIN (Hull Identification Number) and builder's certificate to confirm whether the boat is a purpose-built African Cats basalt/epoxy hull or a modified shell from another South African builder.
- Basalt Fiber Inspection: While basalt fiber (Green Silk) is highly durable and osmosis-resistant when used with epoxy, it is an uncommon material for most yards. Ensure the surveyor is familiar with epoxy-composite inspection techniques to check for delamination or core issues in high-stress areas like the daggerboard trunks.
Community & Resources
The primary resource for technical data is the manufacturer’s archive at African Cats. Owners of South African-built performance catamarans often congregate on technical forums such as CruisersForum to discuss the nuances of Lavranos designs and the maintenance of South African composite builds. While there is no dedicated "Fastcat 50" association, the small number of hulls built means most owners are known within the performance multihull community.
The Verdict
Pros:
- Exceptional performance potential with speeds often double those of standard charter cats.
- Sustainable "Green Motion" technology offers fossil-fuel-free cruising capabilities.
- Lightweight, high-quality epoxy construction resistant to osmosis.
- Daggerboards provide superior upwind performance and a shallow draft for beaching.
Cons:
- Complex mechanical systems (retractable drives) require specialist maintenance.
- Sensitive to weight; excessive cruising gear can neutralize the performance advantage.
- Limited production numbers make parts and community support harder to find.
- High initial price point compared to traditional production catamarans of the same age.
