🔍 Key Concepts

• Safe Working Load (SWL) markings and why they must be independently verified • Role of classification societies vs. role of the flag state/Coast Guard • Limits of the Master’s authority regarding structural gear ratings

💭 Think About

• Ask yourself: who has the technical authority and engineering standards to establish and certify the load a boom can safely handle? • Consider whether the Coast Guard usually performs detailed engineering certification, or if it relies on another type of organization for that function. • Would the ship’s Master be allowed to change or establish a safe working load rating, or only to enforce already certified limits?

✅ Before You Answer

• Verify which organizations are classification societies with rules for hull and cargo gear. • Check whether the U.S. Coast Guard typically approves or directly certifies individual cargo booms on commercial ships. • Confirm that the Master is responsible for safe operation but does not perform engineering certification of lifting gear.
