Under the Boat Safety Scheme and general good practice for inland/coastal leisure craft, what should be done with toilet (sewage) waste when near the shore or in a marina?

A. Direct discharge overboard is always acceptable regardless of location

B. Use a holding tank (where fitted) and pump out at a designated facility, or use shoreside toilets — direct discharge close to shore, in marinas, or in specific no-discharge zones is restricted precisely because of the public health and environmental impact of raw sewage in enclosed or shallow waters

C. Holding tanks are only required on vessels used exclusively for racing

D. Sewage discharge rules apply only to vessels with more than 10 berths

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
