发明名称 Multi-functional sailboard
摘要 A multi-functional sailboard includes a body having a seating section and a dagger. A mast section is connected to the bow of the body and is movable between raised and lowered positions. The mast section includes a stationary mast and a movable mast. The two may be coupled together and slide along a substantially vertical path. The mast section is maintained by a halyard tied to a cleat and a hook and loop fastener is attached to the sail that secures it to the movable mast. A back rest extends upward from the body. A sculling section is secured to the body and includes a traveler, an eye clip, and a cord connected to the eye clip and rudder. The sculling section also includes a spring connected to the rudder and back rest. The rudder returns to an equilibrium position when moved from side-to-side.
