CATALAC 12M

About the CATALAC 12M

Also called CATALAC 41.

The Catalac 12M is a rare, lightweight performance catamaran designed by Tom Lack and built by Tom Lack Catamarans (UK) in 1983, with a total production run of only 27 hulls. Its low displacement of 18500.0 lb and high sail area-to-displacement ratio of 16.07 indicate a vessel prioritized for speed and agility over heavy cruising comfort.

Best for:

This boat suits experienced sailors seeking a fast, responsive coastal cruiser or racer who can manage a lightweight, narrow-beam catamaran with a max draft of 3.07 ft. It is ideal for those who value performance and low draft access over heavy bluewater inventory.

Bluewater capability:

With a capsize ratio of 2.65 and a comfort ratio of 17.21, the 12M is less suited for heavy offshore passages compared to heavier displacement catamarans, making it better for coastal and protected water cruising.

Comparables:

Comparable to other early 1980s performance catamarans like the early Hobie Cats or smaller Lagoon models, but distinct due to its specific Tom Lack design and significantly lower build count. It shares DNA with other narrow-beam, low-displacement catamarans from the UK market of that era.
