Jacob's Ladder
Return To Index
A Jacob’s Ladder is a flexible, portable ladder featuring rope or chain sides with wooden or metal rungs, commonly hung over a ship's side for boarding from small boats or for working aloft. Often used by pilots and passengers, it is designed to be rolled up and stowed, distinguishing it from rigid ladders.
Key Aspects of a Jacob's Ladder
Structure: Composed of vertical rope or chain supports with horizontal rungs, often with long "spreaders" in specialized pilot versions.
Purpose: Primarily used for personnel accessing a vessel from the water, or to provide access to the mast/rigging.
Safety/Usage: Often used interchangeably with "pilot ladder" for boarding, though traditional Jacob's ladders may have different, lighter construction.
Origin: Named for the biblical Patriarch Jacob, who dreamed of a ladder reaching to heaven, referencing the long, often difficult climb from the sea.
Historical Use: In the late 19th century, they were used on warships to replace fixed ladders during battle to prevent the creation of wooden shrapnel.
