The image above was inserted into PowerPoint.
Below, it has been divided into 10 equal segments.
Measure image width at each interval. Divide each width by image length (width/length),
Let us say you want a 70-inch board. Multiply 70 inches by the width/length for each interval. That will be your width for every 7-inch interval.
[However, if you want a specific maximum width for a given length, you will have to play with (proportionally adjust) the width/length ratios:http://bgboard.blogspot.com/2016/01/re-sizing-full-size-surfboard-templa...http://bgboard.blogspot.com/2013/10/picture-to-template-to-resize.html ]

Based on dimensions in the chart Huck posted, and the actual width and length of the image in post #10, the board depicted would be very close to 20" x 74".
Width intervals shown would be every 7.4".
i have has success with the projectors at work.
I insert the pic into word, project on the board whiteboard, measure the dims, on the board. then do a ratio calculation to increase the up and down and then the side to side dims (use percentage increase) in the picture format section in word.
then place some cardboard on the white board with tape and trace away.
doesnt account for the change in shape due to the curve of rocker but it gives a good idea.

You guys are fantastic at this stuff. Thanks so much. If I can pull this off; I'll be in the "Shape Off" at Del Mar in 2019. (LOL). If I don't drop dead from exhaustion first. I will keep you posted on this and update my progress from time to time. Got a lot on my plate. Lowel
