Final answer:
Keep the red buoy on your right side when returning to port, following the 'red-right-returning' rule to navigate safely.
Step-by-step explanation:
When returning to port from Seaword and you see a red buoy, the proper way to proceed is according to the 'red-right-returning' rule, which means you should keep the red buoy on your right side (starboard) when returning from the sea to port. This navigational practice helps ensure that you are following the correct channel and decreases the risk of running aground or colliding with another craft. It's essential for a vessel operator to be familiar with these rules to navigate safely and prevent maritime accidents.
