G'day Aussiecat,
At 73 Kg you are definately in the competitive weight range. <img src="http://www.catsailor.com/forums/images/graemlins/cool.gif" alt="" />
What area do you live in? There may be Mozzie sailors in your area who could help. <img src="http://www.catsailor.com/forums/images/graemlins/laugh.gif" alt="" />
There are probably no figures because each set up is slightly different and what is right for my boat, weight, sailing style, sails and foils is not necessarily right for your boat, weight, sailing style, sails and foils. <img src="http://www.catsailor.com/forums/images/graemlins/crazy.gif" alt="" /> eg. Do you have a wooden boat(home or professional built) or glass boat (Fay, Boyer or Trewin)? Does it have 10", 11" or 12" centreboards? Are your centreboard cases at maximum position aft or not? Sails - Cross Cut, Radial or Tap Drive? Mast - Old heavy section, New light section? Rudders - Size Type. etc, etc, etc. <img src="http://www.catsailor.com/forums/images/graemlins/confused.gif" alt="" />
Sorry but the best way to speed up the learning curve is get the boat on the water as soon as you can and come out and play with the other Mozzies. If you beat us we'll try some of your settings.<img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" /> I've found the Mozzie sailors very aproachable and helpful.
Glad to have you on board and look forward to meeting you on the water. <img src="http://www.catsailor.com/forums/images/graemlins/cool.gif" alt="" />
