Fastcat 605 Information, Review, Specs

Sailing Performance & Handling

The sailing philosophy of the FastCat 605 is rooted in weight sensitivity and aerodynamic efficiency. Unlike the high-drag, voluminous hulls of mass-market cruisers, the 605 utilizes slender hulls with a high bridge deck clearance to minimize slamming in heavy seas. With a displacement that often hovers around 12 to 15 tons (depending on the specific carbon-to-basalt ratio of the build), the power-to-weight ratio is exceptional. This allows the boat to easily exceed wind speed in light airs and maintain high double-digit speeds on reaches without the "hobby-horsing" effect common in shorter, heavier catamarans.

Handling is defined by the use of deep, high-aspect-ratio daggerboards, which provide superior upwind pointing ability—an area where most cruising catamarans struggle. According to technical insights from Lavranos Marine Design, the hull forms were optimized for low resistance across a wide speed range, ensuring that the transition from displacement to semi-planing speeds is seamless. Under power, the 605 was frequently equipped with retractable saildrives that pull completely flush into the hull when sailing, eliminating drag and protecting the propulsion units from marine growth and impact.

Interior Comfort & Variations

The interior of the FastCat 605 is a study in functional luxury, where every component is weight-optimized. The use of honeycomb-core cabinetry and lightweight veneers ensures that the living spaces do not compromise the vessel's performance. The layout typically offers a wide, open-plan bridgedeck salon that integrates the galley, navigation station, and seating area, providing 360-degree visibility.

Due to its semi-custom nature, the 605 can be found in several configurations. The most common is the "Owner’s Version," which devotes an entire hull to a master suite featuring a queen-sized berth, a dedicated office space, and a large head with a separate shower. The guest hull typically contains two double cabins with ensuite facilities. Variations include a four-cabin layout designed for high-end eco-chartering. Sibling models built on similar design philosophies include the smaller FastCat 435 and 445, as well as the larger FastCat 525, all of which share the characteristic plumb bows and emphasis on lightweight construction materials.

Popular Mentions & Media

The FastCat 605 gained significant industry attention during the mid-2000s and early 2010s as a pioneer of "Green" yachting. It was frequently highlighted in technical journals for its "Green Motion" system, which won several innovation awards for its ability to regenerate electricity while under sail. The model has been featured in editorial reviews by Yachting World and Sail Magazine, where it was lauded for proving that electric propulsion and high-performance sailing could coexist in a large-scale cruising catamaran.

Known Issues & Buyer’s Checklist

Prospective buyers of a pre-owned FastCat 605 must focus on the complexity of its integrated systems. While the hulls are exceptionally strong, the bespoke nature of the electrical systems requires specialized knowledge.

1. Propulsion System Health: If the vessel is equipped with the original "Green Motion" electric drives, a thorough audit of the lithium-ion battery banks and the retractable drive mechanisms is essential. Replacement of these custom components can be costly.
2. Daggerboard Trunks: High-performance cats with daggerboards experience significant lateral loads. Inspect the trunks for stress cracking or evidence of grounding, and ensure the lifting tackle and bearings are in good working order.
3. Composite Integrity: Because the boat utilizes carbon and basalt fibers, any structural repairs must be performed by a yard familiar with epoxy-based composite infusion. Check for delamination or "print-through" in areas where high-load hardware is mounted.
4. Rigging Loads: The 605 carries a powerful rig. The standing rigging and chainplates should be inspected for fatigue, especially if the boat has been campaigned in offshore rallies or high-speed passages.

Community & Resources

Owners of FastCats often communicate through the African Cats owner network, though there is no centralized, public-facing association website. Technical support is frequently sourced directly from Lavranos Marine Design, which maintains the original design archives for the FastCat series and can provide stability data and structural plans for refit purposes.

The Verdict

The FastCat 605 is an uncompromising vessel for the experienced sailor who values speed and technical sophistication over the "condo-maran" aesthetic.

Pros:

• Exceptional Speed: Capable of high-performance sailing and superior upwind tracking thanks to daggerboards.
• Advanced Construction: High-tech composite build results in a stiff, light, and durable hull.
• Eco-Friendly: Pioneer in electric propulsion and hydro-generation technology.

Cons:

• System Complexity: The electric drives and complex power management systems require rigorous maintenance.
• Weight Sensitivity: Owners must be disciplined regarding the amount of gear and "clutter" brought on board to maintain performance.
• Limited Availability: As a specialized, semi-custom model, few were built, making them difficult to find on the brokerage market.
