Designers: Tom Lack & John Winterbottom
Tom Lack felt the design was so stable and safe that years ago Lack authorized a £10,000 reward to anybody that could document a Catalac with one hull out of the water. To date, no one has claimed that reward. The reason the boats are so stable is that the relatively short rig combined with the Hard chine hull design allow the boat to unload the sail area by slipping the boat sideways in a sudden gust. It's very hard to turn turtle with this design and this along with the high build quality, is the reason most of these boats are still sailing today.
In addition, it should be noted that these boats have solid Fiberglass hulls which will carry heavy loads far better than many others due to a wider hull-beam ratio, deep rocker design, extreme dead rise hulls with hard chines, and big, powerboat- like transoms (this was written by the noted multihull author, Charles Kanter). They also handle extremely well. Unlike others of that generation, they tack securely without backwinding the jib and handle smartly around docks, easily turning in their own length.
Sailing Rig: Bermudan Sloop / masthead rig
Design Features: Their shallow draft and opening cabin windows all with removable screens make these boats perfect tropical cruisers.

Cruising Catamaran Communiqué
by Charles Kanter
Catalac catamarans, with over 600 units built and sailing, have probably brought as many hours of happy, comfortable and safe boating to more people than any other vessel. It is hard to find any comparable production vessel that has so well achieved its design objectives. One that comes close is the monohull, Morgan Out Island series, the most popular cruising boat ever.
