Abstract
An outrigger sailboat having a drive outrigger hull is disclosed herein. A pair of movable keels is rotatably connected to a bottom portion of the drive outrigger hull. The movable keels are adapted to rotate in opposite directions. A pair of masts is mounted on the outrigger hull. Each of the masts receives a sail. The drive outrigger hull is connected to a load hull by a connector frame. The outrigger sailboat is preferably sailed with the load hull to windward and the drive outrigger hull to leeward. The load hull holds the drive outrigger hull upright even in strong winds. The movable keels act as both keels and rudders to provide directional control.
