William,

Guess it is hard to guess where to start when you have not many others to work off of.
I agree with Col and his comments, but outhaul tension changes with sailmakers, up to about 6" of depth (measured from the boom at the deepest part).
Main sheet needs to be lots and lots tighter to stand the leech up and give you the power it needs...this might be a work in progress for awhile.

I can make you an offer tho'...I will be in NSW for the next 4 months and am happy to help you sort it out...maybe the many years in the class might make it easier.

over to you.
