The number of ships detained over safety issues by the US Coast Guard ticked upward last year, according to the agency's annual port state control report.

Safety-related detentions totaled 105 in 2018, up from 90 in 2017 and 98 in 2016, but down from a 10-year high of 201 in 2015. The bump comes even as the number of examinations dipped to just above 9,000.
