🔍 Key Concepts

• Primary vs. backup means of communication and navigation • Regulatory expectations when required equipment becomes inoperative during a voyage • The difference between what is practical seamanship vs. what is legally required

💭 Think About

• Ask yourself: Does a failed radiotelephone automatically make the vessel unseaworthy to the point you MUST stop, or does it change how carefully you must navigate? • Which option describes an adjustment to your decision-making and risk assessment, instead of forcing you to immediately stop the voyage? • Which answers sound extreme (always/never, must stop immediately) versus those that fit normal marine practice when one piece of equipment fails?

✅ Before You Answer

• Verify which options require you to suspend the voyage outright and whether that is normally mandated just for a radio failure. • Consider whether the rules require you to switch to visual signaling solely because the radio failed, or whether that’s only one of several possible tools. • Focus on the choice that reflects good seamanship and prudent navigation after losing a piece of safety equipment, without adding extra legal requirements that aren’t stated in regulations.
