The Catalac 9M was Tom Lack's first venture into catamaran design. He commissioned John Winterbotham of MG Duff LTD to design the Catalac 9M in 1970. This design was envisioned as the successor to Bill O'Briens venerable Bobcat Catamaran. The Catalac 9M was constructed with solid fiberglass, chined hulls with lots of rocker and deep "V" sections forward which flattened out at the stern. The combination of "V" hulls and rocker, eliminated the need of keels while providing what was thought to be enough grip for windward performance. This was a design with a modest rig, high coach roof, large cockpit and 5 berths in four sleeping areas which provided lots of sun bathing deck space, a shallow draft, and had reasonable performance.
|In a good blow (>20 knots of wind
speed) 10 knots at 45 degress apparent can be expected from the
Catalac 9M and in strong quarterly winds 12-14 knots under sail
has been documented with the outboard engine configuration in a
lightly loaded boat. Remarkable performance from such a boxy design
given that it's design priority was comfort rather than speed.
The Catalac 9M was laid out in two versions. The standard layout had rear locker space for a 30-40hp outboard and the optional layout had aft hull space for two diesel engines. The boats fitted with diesels were well respected for dockside maneuverability.
The standing rigging is over sized to withstand the extra loading experienced by catamarans (the rig doesn't unload because the boats don't heel). 1/4" 1x19 SS on the 9M and 8M. The Catalac 9M was sold with a mainsail, working jib and a 150% Genoa. When the rig is set up correctly, they sail with a very balanced helm. Twin rudders contribute to their agility and later models (>1980) have matching skegs just forward of the rudders to increase windward ability.
The Catalac 9M was a success in the marketplace and 250 were built over two decades.
