Catalac 900 Information, Review, Specs

Sailing Performance & Handling

The Catalac 900 is frequently described as a "motor-sailer" in terms of its performance profile, prioritizing stability and comfort over raw speed. Its naval architecture, penned by John Winterbotham, was famously influenced by the hull shapes of the Sunderland—a British World War II era sea plane—resulting in hulls that are deep and hollow forward before transitioning to a flat aft section. This unique geometry allows the boat to "slip" sideways under heavy pressure rather than lifting a hull, a feature that has led to an unblemished safety record regarding capsizes.

Under sail, the 900 behaves like a tank; it is remarkably steady in a blow but struggles with pointing ability. With a beam-to-length ratio of roughly 2.16, it is significantly narrower than modern performance catamarans, which limits its speed but enhances its tracking. It is a capable downwind sailor, often seeing 6 to 7 knots in favorable conditions, though its high-windage pilothouse and lack of daggerboards mean it can experience significant leeway when sailing closer than 50 degrees to the wind. Owners often note a "hobbyhorse" motion when motoring directly into a short chop, though the boat remains dry and secure thanks to its flared bows and high bridge deck clearance relative to its era.

Interior Comfort & Variations

The hallmark of the Catalac 900 is its fully enclosed pilothouse, which fundamentally changed the on-board experience compared to the older 9M model. Unlike its predecessor, which featured an external helm and a low-headroom sliding hatch that made the saloon feel cramped when closed, the 900 offers full standing headroom of approximately 6 feet 3 inches throughout the saloon and hulls. The enclosed helm allows for all-weather navigation, providing a warm and dry environment for the skipper in any climate.

The layout typically features a "galley-down" configuration in the port hull, with a navigation station and head in the starboard hull. A standout feature of the 900’s bridge deck layout is the master cabin, which is often described as possessing a "king-sized bed"—an extraordinary luxury for a 30-foot vessel. Large, full-length tinted Perspex windows wrap around the saloon, offering the 360-degree visibility that became a Catalac signature. Sibling models based on the same philosophy include the smaller 8M (27), which utilized the same hull molds as the 9M, and the larger 10M and 12M variants, which offered expanded living quarters for blue-water voyaging.

Popular Mentions & Media

The Catalac 900 has earned "legendary" status among the family-cruising community, with its most notable media footprint coming from long-distance voyages that defy its modest size. One of the most documented journeys is that of Jeff and Diane Curran on S/V Horizons, a Catalac 900 that successfully crossed the Atlantic Ocean in 2013. Their passage from the Canary Islands to Barbados, taking 29 days, highlighted the 900's reliability as a blue-water platform despite being significantly smaller than the typical ocean-crossing catamaran.

Known Issues & Buyer’s Checklist

• Window Seal Integrity: The transition to full-length Perspex windows on the 900 improved aesthetics but introduced new leak points. Buyers should inspect the bedding of these large panels, as thermal expansion can cause the sealant to fail over time.
• Tinted Visibility: The standard dark-tinted windows can severely restrict visibility during night watches or when maneuvering in dimly lit marinas. Some owners have retrofitted clear panels or added high-intensity LED searchlights to mitigate this "sunglasses at night" effect.
• Overloading Sensitivity: Due to its massive storage capacity and wide bridge deck, Catalacs are easily overloaded. Excessive weight significantly increases leeway and slows the boat's already modest pace; a pre-purchase survey should note the boat's current waterline relative to factory specifications.
• Osmosis Inspection: While Catalac hulls are exceptionally thick and solid, older fiberglass boats from British yards of this era are prone to osmotic blistering. A moisture meter test of both hulls is essential.
• Rudder Bushings: The 900 utilizes skeg-protected rudders. Inspect the rudder bearings and bushings for play, as years of "steering with the throttles" in tight quarters can accelerate wear.

Community & Resources

The primary hub for technical knowledge and owner history is the Catamaran Cruising Association, which maintains an extensive archive of original Catalac brochures, technical specifications, and owner-led modifications. This community is instrumental in helping new owners source parts for the 900's specific sail-drive configurations and provides a historical record of the brand's evolution from the early Tom Lack designs.

The Verdict

The Catalac 900 is a "floating cottage" that offers safety and interior volume far beyond its 30-foot length. It is the ideal choice for a small family or a couple looking for a stable, all-weather coastal cruiser with the occasional ambition for blue-water passages.

Pros:

• Safety: Exceptionally stable hull design with a zero-capsize history.
• Livability: Full standing headroom and a master cabin that feels twice its size.
• Build Quality: Solid fiberglass construction that is notoriously overbuilt.
• Draft: A shallow 2.5-foot draft allows access to anchorages closed to most monohulls.

Cons:

• Upwind Performance: High leeway and windage make tacking through 70 degrees difficult.
• Speed: A slow performer in light winds; often requires motor-sailing to maintain schedules.
• Scarcity: With only roughly 20 built, finding one on the used market is a rare occurrence.
