Submarine Cables and Pipelines
I was recently anchored in a beautiful spot between two islands wondering why I was the only boat there. I looked around and saw a cable crossing sign on one of the islands. I quickly checked my charts and realized that I had unchecked the optional feature in Coastal Explorer (under vector chart options) for showing Submarine Cables & Pipelines. Realizing my error, I promptly weighed anchor and moved. You may want to check your charting software settings too. Not a problem with raster charts however. Also, looking around at some anchorage locations in Active Captain, I noticed several anchorages in the middle of cable/pipeline areas. I relocated them using the AC website. So beware and don't just take someone else's 5 star rating to mean it actually is an excellent anchorage!
