===Stringer===
In board design, the "stringer" is a board's central plane of reflection, down the middle of its deck and its keel. In construction, the stringer can have no special parts, or can embed a stiff, thin, vertical slat, usually of wood but sometimes of [[carbon fiber]], running from nose to tail.  The stringer serves to increase the board's overall strength and reduce its flexibility. Some boards have multiple stringers.
