The Catalac 8 M is a compact yet remarkably spacious cruising catamaran, renowned for its robust construction and practical design. Often referred to as the Catalac 27, this model was conceived as a shortened version of the popular Catalac 9M (Catalac 30), sharing its fundamental hull design. Built by Tom Lack Catamarans Ltd., a pioneering UK manufacturer of fiberglass multihulls, the 8 M embodies the builder's philosophy of creating strong, safe, and seaworthy vessels for family cruising. The original design for the larger 9M, from which the 8M is derived, was a collaboration between Tom Lack and naval architect John Winterbotham of MG Duff LTD.

Production of the Catalac 8 M commenced in 1975. Tom Lack Catamarans Ltd. operated from the early 1970s until around 1985, focusing on refining its core design philosophy of robust, practical cruising catamarans. While the company ceased operations in the mid-1980s, some sources indicate that Catalac 8Ms continued to be produced through at least 1990, and possibly up to 2002, suggesting extended production runs or later licensed builds. A total of 212 Catalac 8 Ms were built, making it a significant model in the brand's history.

The design ethos behind the Catalac line, particularly the foundational 9M and its sibling 8 M, emphasized strength and seaworthiness. Tom Lack, with John Winterbotham's expertise, aimed to create dependable fiberglass catamarans well-suited for comfortable family cruising and extended voyages, 8, 20]. A notable characteristic of the 8 M is its use of the same hulls as the larger 9M, showcasing a modular approach to design and construction, 19]. This shared lineage ensured that the 8 M benefited from the proven, sturdy hull form of its predecessor.

Sailing Performance and Handling

As a catamaran under 30 feet, the Catalac 8 M prioritizes stability and living space over high-performance racing characteristics. Opinions on its sailing performance vary, with some early brochures suggesting "remarkable" performance even in light airs, capable of reaching speeds up to 7 knots. However, some owners report that the boat "does not sail well in light winds," struggling to move in anything below approximately 10 knots. Conversely, the 8 M is praised for its ability to handle challenging conditions, with one owner recounting its successful navigation through a gale in the North Sea.

Owners generally describe the Catalac 8 M as "strong, sturdy, and sea-kindly". It is noted for its stability and comfortable motion, with no bridge deck slamming issues reported by some owners. While some suggest it can be "difficult to handle and doesn't tack gracefully", other reviews indicate "excellent" handling qualities. The boat is capable of motoring at around 6 knots and sailing at 7 to 8 knots.

Accommodations and Layout

Despite its modest length overall of 27 feet, the Catalac 8 M is celebrated for its surprisingly generous interior volume, often noted as offering significantly more internal space than an equivalent length monohull. The design emphasizes practical and comfortable family accommodation. The interior typically features a compact yet efficient layout designed for cruising. The deck plan includes a large cockpit, providing ample outdoor living space. Owners frequently commend the thoughtful design of the cabin. While specific headroom figures are not consistently available, the emphasis on interior space suggests a comfortable living environment for its size. The general finish quality aligns with Catalac's reputation for robust, no-nonsense construction, prioritizing durability and function.

Owner's Perspectives

Owners of the Catalac 8 M consistently praise its solid construction and stability, highlighting its suitability as a dependable and comfortable cruising platform. Many appreciate the low maintenance requirements for a boat of its age, with one owner describing it as "amazingly low maintenance". The boat's ability to handle heavy weather and provide a safe ride is a frequently mentioned strength. The generous interior space, particularly for a 27-foot catamaran, is also a significant draw for those seeking extended cruising comfort.

However, some common points of discussion among owners include varied opinions on its light-wind performance and maneuvering characteristics, with some finding it less agile than other designs. A recurring maintenance item noted by some owners is the need to reseal windows, as they can develop leaks over time. Despite these minor points, a strong and active community of Catalac enthusiasts exists, reflecting the enduring appeal and practicality of these classic multihulls, 4, 24].
