Original sentence: From this 3D design, the two-dimensional flat sections are created to become the precision-cut frames (internal Rib-like structures perpendicular to the mid-line) and keel (also called stringer in a foam surfboard), then carefully select graceful, bookmatched wood that blends together to form a unique pattern on the deck and bottom of the board
Edited sentence: From this 3D design, the two-dimensional flat sections are created to become the precision-cut frames (internal Rib-like structures perpendicular to the mid-line from nose to tail) and keel (known as stringer in a foam surfboard), then carefully select graceful, bookmatched wood that blends together to form a unique pattern on the deck and bottom of the board.The hollow and watertight nature of these  boards require the installation of a Gore-Tex vent plug to equalize internal and external pressure changes from heat extremes and atmospheric pressure due to changes in elevation which causes air pressure inside the hull to expand and may lead to delamination
