ABSTRACT:
A mast raising and lowering device for sailboats, and particularly sailboats with outboard rudders, which embodies a telescoping pole topped with a roller assembly, the device being attached to the stern of the sailboat where it is used to movably raise and support the mast in a partially elevated position during mast raising and lowering operations. The telescoping pole is attached to the stern of the sailboat by pintle-like pins, which are vertically adjustable on the pole to fit existing gudgeons provided for rudder support and pivoting. The upper section(s) of the telescoping pole is vertically positionable at various extended locations by a pin member. The roller assembly, on the top of the uppermost telescoping pole section, contains a roller member for ease in moving the mast therealong, and may be provided with a pair of flared ears positioned on either side of the roller to aid in receiving and containing the mast. The roller provides a location for retention of the mast during trailering or moorage.
