What is the main reason many popular anchorages now provide (or are moving toward) eco-moorings rather than allowing free anchoring?

A. Eco-moorings exist purely to generate mooring fees, with no environmental purpose

B. A conventional anchor and chain drag and reset repeatedly across the seabed as the vessel swings, which over time and repeated use can damage sensitive habitat like seagrass — an eco-mooring uses a fixed point and often a floating or elasticated line that keeps ground contact away from the seabed entirely

C. Eco-moorings are stronger than any anchor and are provided solely for holding-power reasons

D. Eco-moorings are only ever used in freshwater lakes, never in tidal or coastal waters

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
