Hi Mike,
The best website for setup and tuning guides for all nacra's is www.goosemarine.com.au (the owner of this site is also the WA Nacra Dealer), if you go to the articles section theres a nacra assembly manual (original), in there is a step by step guide to raising and lowering the mast with pictures etc...
If you would like some setup tips or even some one to show you how to set the boat up, come down to koombana bay sailing club (bunbury) on race day and one of the nacra guys can help you. Koombana Bay Sailing Club is the home of NACRA in WA with 8 boats racing there.
If you have any questions contact Gary Gornall;
