Which type of ladder is referred to as Jacobs Ladder?

Jacobs Ladder refers specifically to a type of rope ladder characterized by wooden rungs suspended between lines of rope. This design allows for flexibility and ease of use, particularly in situations where a temporary or portable ladder is required, such as boarding a vessel from a small dinghy or maneuvering in tight spaces. The combination of the flexible ropes and the sturdy wooden rungs gives it unique advantages in marine environments.

While the other options describe different types of ladders that may serve specific functions in various maritime situations, they do not align with the characteristics that define Jacobs Ladder. An understanding of this distinction is crucial for recognizing the specific utility and application of Jacobs Ladder in boating and nautical contexts.
