Moving the Widepoint of a Surfboard Template

To move the widepoint, you adapt the method used for resizing a full-size surfboard template (basic math based).  Follow this link for the full-size template method:

Basically, you re-size the template as two different sections.  The front section is from the widepoint forward and the rear section would be from the widepoint to the tail.  It is not complicated but takes a bit of thought to see it.

You re-size the length of the front and rear sections of the template independently/separately.   The original template widepoint is the dividing line between the front and rear sections. You increase and decrease the lengths of each section accordingly to move the widepoint forward or backward.

To move the widepoint back 3 inches, you would lengthen the nose section by 3 inches and shorten the tail section by 3 inches.  To move the widepoint forward 3 inches, you would shorten the nose section by 3 inches and lengthen the tail section by 3 inches.  Use the same math-based method you would use to lengthen and shorten a full-size template (see link above).

I may expand this disussion with some diagrams at a later date...
