A stiffening or damping apparatus for sliding boards or skis, comprising a force transmission blade (20) attached to the sliding board (10) for transmitting vibrational, twisting or bending energy and a clutch element for engaging the force transmission blade. The clutch element (26) can be constructed to engage in both directions of ski bend over only a portion of total possible movement, or to frictionally engage (44) in only one direction of ski bending. These clutch devices allows the ski to be damped or stiffened only for small ranges of vibrational movement or to be inhibited in a single direction of bend or torsion.
