how big does the ocean have to be to keep them from running into each other
In this case it didn't happen on the ocean.
Maybe the watch should be doubled when sailing in congested waters or areas of limited maneuvering room at night. There’s just no way 2 ships should EVER get close enough to collide. If it means there’s no mid rats because the cooks are on the rail with NVGs or some sailors don’t get to go to bed that night, then so be it.
