SUBMARINE CABLES AND PIPELINES Mariners are advised not to anchor or trawl in the vicinity of submarine cables and pipelines. Pipelines are not always buried and their presence may significantly reduce the charted depth. They may also span seabed undulations and cause fishing gear to become irrecoverably snagged, putting a vessel in severe danger. NATURE RESERVES According to Afkondigingsblad Bonaire 8/1991 the area around Bonaire and Klein Bonaire between the high-waterline and the 60 metre depth contour is appointed as Nature Reserve. In the coastal area between Karel’s Pier and the S-ly jetty near Kralendijk anchoring is allowed only with the expressly written permission of the local authorities.
