Abstract
A foldable mast assembly for sailboats wherein a main mast is pivotably connected to a stub mast which is pivotally connected to a base secured to the sailboat deck. A removable pin extends between the stub mast and base whereby the main mast and stub mast may be folded to an inoperative position substantially parallel to the main deck and centered approximately lengthwise of the sailboat. The folding and raising of the main and stub masts are controlled by a cable reeved through sheaves carried on the main and stub masts, one end of the cable being connected to the fore deck near the bow of the sailboat and the other end connected to a power winch on the aft deck of the sailboat. In smaller sailboats, having small masts where cables and sheaves are not required, the folding and raising of the main and stub masts can be accomplished manually.
