Quite recently, with the fishing vessel safety regs, we have been quite clear that, if a vessel has a stability assessment—vessels are now required to get stability assessments under certain considerations—and then that vessel has been modified, they have to keep a record of the modification and they have to do another stability assessment. The new fishing vessel safety regs—and they have only been in place since July 13, 2017—were a change Transport Canada made partly in recognition of that very problem. Any vessel that has a hull length more than nine metres that's had a major modification—including extensions, cutting things off, and adding anything, or undergone a change in activity since July 13, 2017, that could adversely affect its stability—is required to undergo another stability assessment by a competent person; there's a licensed group of people who do this.
