Why is your wash (wake) a genuine environmental and safety consideration when passing moored boats, riverbanks, or shallow anchorages at speed?

A. Wash has no real effect once a vessel is more than a few metres away

B. Excessive wash can cause riverbank erosion, disturb nesting birds and other wildlife, and cause moored or anchored boats to surge against their lines or each other — slowing down through sensitive or crowded areas is a simple, standard courtesy and precaution

C. Wash is only a legal concern for vessels over 24m in length

D. Riverbank erosion is entirely unrelated to vessel wash

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
