How common are scenarios where there are multiple ships within visual distance? From reading the account of the collision, it seems like everybody relied primarily on one radar to make navigation decisions, and that radar was either broken, or its operators didn't know how to use it. It's hard for me to understand how they didn't realize they weren't getting useful data from that radar and switch their primary navigation driver to the other radars, lookouts, the commercial position broadcasting system, or the infrared camera, all of which seemingly worked. Unless of course actually navigating around other ships is pretty uncommon.
