ABSTRACT:
A sailboat mast ladder, for use with a sailboat having a mast with a sail track extending along its length, includes a flexible, flat support strap having a number of foot loops, also made of flat strap material, at staggered positions on opposite sides of the support strap. The support strap and foot loops are formed from first and second flat straps each having alternating straight sections and foot loop sections, the foot loop sections of one strap being opposite the straight sections of the other strap. The bottom or instep portions of the foot loops are reinforced with flat strap material secured to the first and second flat straps. An end of a halyard is secured to the upper end of the support strap to raise the mast ladder up the mast. A number of guides are secured along the inner edge of the support strap for sliding engagement with track slides of the main sail track to keep the ladder against the mast.
