ABSTRACT:
A mast ladder for going up the mast of a sailing craft having a mast with a sail slide extending along the length of the mast including a halyard slide, a plurality of connecting rods, a top step and a plurality of universal steps. The mast ladder is assembled by attaching an end of the halyard to the upper end of the halyard slide to raise the mast ladder up the mast. The halyard slide, the top step and each universal step engage the sail slide keeping the mast ladder against the mast and providing support to each step. As the mast ladder is raised, the halyard slide has a connecting rod attached at the lower end and the connecting rod is attached to the top step at the upper end and a subsequent connecting rod is attached to the lower end of the top step and to the first universal step at its left or right hand position, which are alternated as the mast ladder is raised to the desired height necessary to complete the work on the craft.
