ABSTRACT:
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.
