I would suggest that, if the authorties suspect something illegal they could go anytime out and check the vessel, that is also possible with no problems in international waters nowadays..
When I see the track and the time, waiting for orders could be. But waiting then that close
is rather unusual. Only one thing I can clearly see as Master,,it would be outright stupid to stay 19 days in the same area with no orders from the company/owners/operators etc, and doing at the same time something illegal, would border on the insane. And with orders even worst !!!
But that,s what I say now and before, because of the open AIS systems,, peoples see something, make suggestion, assume possibilities, opening blogs and nobody knows what is really going on, the perfect recipe for more rumors
