If you witness a pollution incident at sea (for example, an oil sheen or a discharge from another vessel), what is the correct action?

A. Ignore it, since pollution reporting is only the responsibility of commercial vessels

B. Report it to HM Coastguard (via VHF Ch16 or the Coastguard directly), noting position, time, and a description of what was observed if it is safe and practical to do so

C. Attempt to clean up the pollution yourself using whatever is on board

D. Only report the incident if you personally caused it

A. Plastic may be discharged more than 12nm from land

B. Discharge of all plastics into the sea is prohibited everywhere, with no distance-from-land exception — plastic waste must always be retained on board and disposed of ashore

C. Plastic may be discharged if it is cut into small enough pieces first

D. The rule only applies to vessels over 400 gross tonnes

A. Fill as fast as possible to minimise time at the pump

B. Slow down as the tank approaches full, listen/watch for the tone or sight change indicating it's nearly done, and use a drip tray or absorbent pad under the filler and any vent to catch spillage or overflow

C. There is no real risk of spillage from a vent pipe, only from the filler itself

D. Environmental precautions are only necessary when refuelling from a jerry can, not at a fixed fuel berth
