Chile also pioneered in the emission of reports at short intervals. Prior systems had focussed on "where is the vessel" with the provision of hourly reporting. The Chilean system, by dropping the minimum report interval to 8 minutes is capable of determining "what" the vessel is doing. When you see a series of circular positions, they are all at speeds of below and reflect the drift of the current—there is no question, that vessel was purse seining, and the printout of the chart can be shown to the court to demonstrate the fact.
