How can I help to protect it?

  • I use environment-friendly mooring techniques to limit the impact of anchoring
  • In the case of anchoring out at sea, I only anchor in areas where marine habitats are not fragile and raise the anchor vertically
  • I do not disturb marine wildlife. Look but don’t touch!
  • I avoid contact with the seabed and with sloping faces
  • I avoid repeated and long visits to caves
  • I report any unusual environmental incidents
  • I recover waste and dispose of it in suitable bins on land
  • I do not gather souvenirs from the sea
  • I share this best practice with other seafarers and raise their awareness.
