Maritime Questions › Day Skipper — Marine Environment
Why might anchoring directly on a seagrass meadow cause lasting environmental damage, compared to anchoring on bare sand or mud?
A. Seagrass grows back within hours regardless of any disturbance
B. An anchor and chain dragging or resetting across seagrass can uproot and scar the meadow, which recovers extremely slowly (often years) and provides important nursery habitat, carbon storage, and seabed stabilisation that bare sand doesn't
C. Seagrass is not protected or ecologically significant in any way
D. Anchoring on seagrass is only a concern in tropical waters, never in UK waters

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
