Thickness is possibly the most important parameter for the PP designer.

Comparing two boards of the same length, width, and volume, one a tapered profile board and the other parallel, it is always the case that the PP board will have the lower maximum thickness measurement.  Thus the maximum thickness measurement from a tapered profile board should not be used for a parallel profile board as it will make the PP board have a lot more volume than expected.

Typically a PP board will be .75  to 1.5 inches thinner than the tapered profile board.

If in doubt it is best to calculate the relative surfboard volumes in order to arrive at the correct thickness, rather than going ahead with an overly thick and overly voluminous shape.

The thickness number will seem disturbingly low at first, but that's the key to two of the main advantages of the PP system, namely a low centre of gravity and mass for improved control, and flexibility.
