[CA] [CA11] Can't get rocks to NOT display

[Chuck - Raymarine - Moderator]

A1. As I believe that you have already done, rock objects are hidden via the Show Rocks (MENU->PRESENTATION->CHART OBJECTS->SHOW ROCKS) configuration setting. When configured to a range, all rock objects which have a listed depth greater than the upper limit of the configured range will be hidden. Having done this, you have done all that may be done via the MFD's user interface. As you had suggested, as the rock objects have no depth associated with them, the MFD's software is not handling that case and will not hide rocks lacking a populated depth attribute. It can be stated that rock objects have a depth associated with them may reliably be hidden via the Chart application's Hide Rocks configuration setting. Should Navionics make the required updates to the cartography to include depths for these rock objects, then I would expect that the Chart application's Hide Rocks configuration setting would indeed hide them.
