ABSTRACT:
A collapsible mast assembly for a sailboat includes a mast support which is mounted on the boat deck for supporting the lower end of the mast. The support includes upstanding side walls and a lower rear wall to which the boom is attached. A mast plate is mounted within the mast support at the bottom thereof and is adapted to fit within the open lower end of the tubular mast. The mast is lowered by loosening its stays and then lifting the same until its bottom is above the level of the mast plate. At that point the mast can be tilted backward toward a horizontal position where it rests and pivots on the top of the rear wall as the bottom of the mast pivots upwardly through the open front of the mast support. In the horizontal position, the mast can be moved rearwardly or forwardly as desired. The boom is secured to the rear of the mast support so that movement of the mast is independent of the boom.
