What is described as a stout plank attached with two short wooden horns for support?

The description of a stout plank that is supported by two short wooden horns aligns closely with the concept of a stage. In nautical terms, a stage refers to a temporary working platform often used for construction or maintenance tasks on a ship. The design typically involves sturdy planks and supports, which is consistent with the description provided.

A stage is designed to elevate workers above the main deck, allowing for easier access to the upper parts of the vessel.
