And many ships fly the flags of so-called countries of convenience that offer cheap registration fees and tax breaks but may not have robust oversight.

“There’s no strong infrastructure for safety in maritime," said Jim Hall, who led the National Transportation Safety Board from 1994 to 2001. «And there’s a lack of adequate oversight of what we have because the Coast Guard is essentially underfunded and doesn’t have the adequate manpower to do the many jobs it is given to do.”
