Jacob's ladder, in a maritime context, refers to a flexible and portable ladder made from rope or chain, with wooden or metal rungs, which is primarily used aboard ships. It is designed to be easily deployed and lowered over the side of a ship from the deck and is often used for the transit of people, such as pilots or passengers, to or from smaller boats or the water whilst the ship is moored or at sea. Its name is derived from the biblical dream of Jacob, which describes a ladder extending from Earth to Heaven. Jacob's ladder is convenient for situations where a rigid ladder would be impractical due to storage, maneuverability or deployment considerations.

Jacob's Ladder, in a nautical context, is a rope ladder that is lowered from the deck of a ship for purposes such as welcoming aboard pilots or passengers. However, what makes this type of ladder particularly interesting is its mystical name reference and the role it has played in history and pop culture. The term "Jacob's Ladder" originates from a biblical story in the Book of Genesis where Jacob dreams of a ladder stretching from Earth to Heaven, with angels ascending and descending it. In the nautical world, this rope ladder serves as a symbolic bridge between the ship (earth) and the sky above (heaven). Interestingly, Jacob's ladders have been used historically in many significant maritime voyages. For instance, they were utilized in expeditions of exploration during the era of sailing ships and even by pirates for boarding enemy vessels. Despite advancements in technology, the Jacob's ladder is still used in modern seafaring due to its practicality and simplicity. Additionally, Jacob's Ladder has found a place in the world of entertainment. It has featured in several films, books, and songs. For example, in the film "Master and Commander: The Far Side of the World," the main characters use a Jacob's Ladder to board their ship. Overall, while Jacob's Ladder might seem like just a simple rope ladder, it carries a rich background, merging history, symbolism, and pop culture, thus making it a fascinating aspect of maritime life.
