From the article:
For a brief period, it appeared that the Scottish courts might intervene. An interim interdict was granted to prevent the removal of the master and first officer while the legality of their detention was considered. But during court proceedings it emerged that the two men had already been transferred from Marinera to the US Coast Guard cutter Munro , which had sailed beyond UK territorial waters.
How much responsibility can realistically be placed on a master to verify the legality of a voyage when ownership, chartering and cargo interests are deliberately opaque? What legal protections exist if senior officers become the focus of enforcement action? And how will recruitment, crewing and insurance be affected if certain trades are perceived as carrying unacceptable personal risk?
