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 raised by engaging the top step with the sail slide and attaching a connecting rod to the lower end of the top step and raising the top step. The top step, each universal step and halyard slide, engage the sail slide keeping the mast ladder against the mast and providing support to each step. As the mast ladder is raised the top step has a connecting rod 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 with a connecting rod between each universal step with the halyard slide connected upside down to the last universal step allowing the mast ladder to rest on the halyard slide so that the work on the craft may be completed.

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.
