Step 1: Understanding the Anatomy of a Ship's Anchor:
A standard naval anchor (such as the stockless anchor) consists of massive cast steel parts designed to dig into the seabed to hold the ship in place.
Step 2: Identifying the Anchor Components:
• Shank (C): The long, central vertical stem of the anchor to which the anchor cable is attached via a shackle.
• Fluke (A): The large, flat, shovel-like parts of the anchor that pivot and dig into the seabed to provide holding power.
• Pea or Bill (B): The very tip or extremity of the fluke that initially pierces the ground.
Step 3: Identifying the Exception:
Blake Slip (D): A Blake slip is a general-purpose heavy-duty mechanical stopper mechanism fitted on the forecastle deck. It is used to temporarily grip and secure the anchor chain (cable) to take the strain off the windlass. It is a part of the deck's cable rigging gear, not a physical part of the anchor itself. Thus, option (D) is correct.
