How to calulate tow hook location

I am currently working on a 2 meter sail plane. I obtained a Kanza fuse from Matney models. He did me a favor and cut the foam wing cores for me. And then being the best guy he is! He helped me put on the obichie wing skins and bag them. So this is a straight wing bird with Full house wing. Now Here is my question. How do I calculate where to put the tow hook? And where should I expect the C.of G. or C.of P. to be located at? Ball park will do. I have to hurry and finish this soon as I want to take this to the NATS So any thoughts or opinions would be welcomed.
