Mast raising mechanism for sailboat

机译:帆船桅杆提升机构

摘要

The mast raising mechanism operates on a hinged mast and includes an elongated base section that is removably attached to the lower mast section that is uprightly affixed in the boat. An elongated extender section is telescopically extended from the base section and is locked in place. A pulley is mounted at the top of the extender section. A line, attached to the mid region of the mast, passes over the top of the pulley and the end of the line is acted on by a crank which is on the base section. Due to the height of the base section plus extender section, and due to the angle of the line, a person can easily wind up the line and raise the mast.
