Which of the following is an example of "user charts" that should be annotated on ECDIS?

• A. Environmental data and tide information
• B. Route and waypoints, own ship, and planned anchor swing circles
• C. Weather forecasts and navigational alerts
• D. Previous voyage data and cargo information

Answer: (B)

User charts in an ECDIS context refer to information that the mariner adds to the electronic chart system to enhance navigation safety and efficiency. The inclusion of routes and waypoints, as well as the own ship's position and planned anchor swing circles, is essential for personalized navigation. This data is specifically tailored to the vessel's operational requirements and the mariner's navigation strategy. By annotating the ECDIS with routes and waypoints, the mariner can create a clear plan for their voyage, ensuring that they follow their intended course while maintaining situational awareness. Including information about the own ship's position helps the navigator verify that they are on track, while planned anchor swing circles assist in planning mooring operations safely, taking into account the potential swing of the vessel in different environmental conditions. The other choices may convey valuable information for navigational purposes, but they do not specifically fall under the definition of user charts as they are generally provided by external sources or authorities rather than personalized additions made by the vessel crew.
