About the CATALAC 10M
Also called CATALAC 34.
The Catalac 10M is a compact performance catamaran designed by Tom Lack and J. Winterbotom, with 45 hulls built between 1984 and 1988. Built by Tom Lack Catamarans and Hythe Marine Services in the UK, this model represents a niche segment of early 1980s British catamaran production.
- Best for:
- This boat suits coastal cruisers and short-range offshore travelers who prioritize shallow draft and agility over heavy bluewater comfort. Its lightweight displacement and narrow beam make it ideal for owners seeking a manageable, trailerable catamaran for protected waters.
- Bluewater capability:
- With a displacement of 12300.0 lb and a capsize ratio of 2.65, the boat is suitable for coastal cruising but lacks the heavy displacement and motion comfort typically required for extended bluewater passages.
- Comparables:
- Comparable boats include the Lagoon 320 and Fountaine-Pajot A320, which offer similar beam and interior volume but with greater displacement and stability. The Catalac 10M distinguishes itself with a significantly lighter displacement and a more performance-oriented hull form.
