Maritime law is, perhaps, at its most dramatic when it comes to ship collisions. Often lawyers will seek to identify “Red Flags” which hint at problems onboard, and which have likely contributed to the incident. A “red flag”, in English, means “a glaring problem”. Avoiding red flags means that glaring problems are being avoided; of course, this can be done honestly, i.e. by not causing the problems to begin with, or dishonestly, i.e. by covering up the problem after the fact. Manipulation of evidence does occur, changes to navigation plots or logbook entries. But seafarers are reminded that any falsifications can lead to criminal penalties.
