A wind propelled sailing apparatus having a sailboard hull adapted to support a user; a sail for propulsion of the sailboard hull and adapted to receive wind for motive power; a skeg positioned and oriented in a rear central portion of the sailboard hull, the skeg being adjustable between a first position, whereby the skeg has a surface area sufficient to provide lateral resistance to side forces generated by the sail and to provide directional stability to the sailboard hull when sailing upwind, and a second position, whereby the area of the skeg is reduced for sailing downward; and a housing for the skeg which facilitates vertical upward and downward movement thereof, the housing having an opening configured and positioned about the skeg to minimize air entrainment between the housing opening and skeg to the underside of the sailboard hull due to forward movement thereof.

A wind propelled sailing apparatus comprising a sailboard hull adapted to support a user; means for propulsion of said sailboard hull and adapted to receive wind for motive power; a skeg positioned and oriented in a rear central portion of said sailboard hull as the sole means for providing lateral resistance and directional control for the apparatus, said skeg being adjustable between a first position, whereby said skeg has a surface area sufficient to provide lateral resistance to side forces generated by said propulsion means and to provide directional stability to said sailboard hull when sailing upwind, and a second position, whereby the area of the skeg is reduced for sailing downwind; and means for housing said skeg and facilitating vertical upward and downward movement thereof, said housing means having an opening configured and positioned about said skeg to minimize air entrainment between said housing opening and skeg to the underside of the sailboard hull due to forward movement thereof and to prevent water from being forced upward through the housing opening from beneath the sailboard hull; wherein said housing extends beneath said sailboard hull for providing directional stability to said apparatus when said skeg is retracted toward said second position.
