The correct answer is C) usually drawn for the port side only. The half-breadth plan is a view that shows a cross-section of the ship's hull, usually drawn for the port side only. This view allows for the detailed depiction of the ship's shape and dimensions at various points along the length of the vessel. The half-breadth plan is an important part of the ship's construction documentation and is commonly used in naval architecture and shipbuilding. The other options are incorrect because: A) describes the profile view, B) describes the body plan, and D) describes the sheer plan, which are all different types of ship plans.
