Unfortunately there is no easy way to accomplish what you wish. I spent all summer re-rigging our 08' Infusion to be race ready (it was in good sailing condition beforehand). Mike and Tripp's site is a huge help, but three times I took measurements off their boat and others in person to get things sorted more accurately. Remember they post finished line lengths and some splices require quit a few feet of line.
Here is the official Nacra parts manual:

I ended up referring to the Nacra 17 manual as they have an extremely detailed rigging list:

In the end, depending on what you are trying to do with your boat, you may be better off calling your dealer and asking for a new lines package. I've been told the Infusion Race Package is expensive relative to the cost of the line itself, but most of us have some $ value on our time.
