Instructions (book) call to locate the forms in relation to the outside of the completed boat. How do you know how far the strips will extend beyond the point of the end form to determine where the form placement should be (i.e. where to start measuring from or how much to substract from the distance if measuring from the point of the end form)? I am sure its there and I just missing it, but would appreciate someone clearing it up for me.

Thanks,

Joe
