Sail board foot repositioning system

A foot repositioning system for a sail board having a top surface, a bottom surface, a bow, a stern, and two elongated rails interconnecting the bow and stern, said bow and stern defining a sail board longitudinal axis, said sail board bottom surface having one or more skegs attached thereto generally near to the sail board stern, said sail board having a mast attached to the sail board top surface along a sail board central longitudinal axis, between a sail board longitudinal midpoint and the sail board bow, said foot repositioning system being attached to the sail board top surface between a sail board longitudinal midpoint and the sail board stern, said foot repositioning system comprising:

• a circular bottom plate having a flat top surface, a flat under surface, a perimeter edge, a central holding aperture at a bottom plate center, and two operator apertures formed therein 180 degrees apart, each operator aperture having a 180 degree side with a radial slope extending upwardly from the circular bottom plate under surface to the bottom plate top surface, generally parallel to the bottom plate perimeter edge and in the radial direction of the other operator aperture slope, each operator aperture having a curved reinforcing stop element attached to the bottom plate top surface about the operator aperture, non-sloped side, wherein the bottom plate undersurface is joined to the sail board top surface;
• a flat, generally rectangular top plate having a top surface, an underside, two opposite longitudinal sides and two opposite transverse sides, said top plate longitudinal sides aligned generally with the longitudinal axis of the sail board, said top plate has a central aperture and two perimeter apertures, 180 degrees apart, said top plate having a pair of flat, elongated, parallel support rods in a spaced, parallel relationship with each other, each joined to a top plate longitudinal side, each said support rod having opposite ends, said ends terminating in a foot plate, each foot plate having a top surface and a foot strap attached to the foot plate top surface;
• wherein the top plate underside is padded with a circular plastic disk having a top surface, a bottom surface, a circumferential perimeter, a central aperture and two perimeter apertures corresponding to the top plate central and perimeter apertures;
• a holding ring is mounted on the plastic disk bottom surface on a plastic disk annular surface portion adjacent the plastic disk perimeter, said annular surface portion having a radial width less than the distance between a perimeter aperture and plastic disk perimeter, said holding ring attached through the plastic disk to the top plate underside, said holding ring having a circular central opening exposing the top plate and plastic disk apertures;
• wherein the top plate with plastic disk and holding ring are placed over the bottom plate;
• said bottom plate having a diameter less than the diameter of the holding ring central opening, said bottom plate, top plate, and plastic disk with holding ring are joined together by a central fastener through the central apertures of the bottom and top plates, wherein said bottom plate operator apertures, top plate perimeter apertures and plastic disk perimeter apertures are aligned with each other;
• two locking pins, each contained within a locking pin housing, said locking pin housing comprised of a hollow cylindrical element having an sidewall, extending from an open locking pin housing bottom to a locking pin housing open top, said locking pin housing sidewall having an external surface and an interior surface, said locking pin housing sidewall, top and bottom defining a hollow locking pin housing interior, said locking pin housing interior surface threaded near to the locking housing bottom and adapted to threadingly engage an open nut external threads, said locking pin housing external surface threaded near to the locking pin housing top, wherein a threaded cap threadingly engages the locking pin housing top;
• wherein each locking pin is an elongated solid cylinder having a top and a bottom, said locking pin partly and slidably contained within an electromagnetic solenoid contained within an interior housing, said interior housing contained within the locking pin housing interior, said locking pin bottom protruding from the locking pin housing into and through a top plate perimeter aperture and into a bottom plate operator aperture, wherein each locking pin top has an elastic material connecting the locking pin top to the interior housing thereby nominally forcing the locking pin bottom to protrude downwardly from the locking pin housing bottom;
• wherein each solenoid is remotely and individually activated causing a specific locking pin to move upward out of a specific bottom plate operator aperture.
