G'day Aussiecat,

I've seen people sailing mozzies cat rigged from about 55 kg to 120+ kg. There is no offical minimum crew weight that I'm aware of. However at 55 kg, you might struggle in winds over about 15 knots. At 120 kg you might struggle in winds under 10 knots. Then again skill will overcome weight. <img src="http://www.catsailor.com/forums/images/graemlins/wink.gif" alt="" />

I think the tuning guide is currently being reviewed.

The Vic Mozzie Website has some info on rigging.
