I agree with you 100%, but I am looking for something that obligates this particular instrument to be on board. Having one, for instance, will help you in court, even though it may not be required, if the readings were recorded and logged showing that you were “in fact” moving away from a hurricane, but this can be subjective and can cause harm to a prudent mariner if the hurricane changes course and picks-up speed and the logs show the exact opposite, which can possibly happen.
I find this very interesting after an auditor said you are operating illegally without one. I think he is full of sh#^, but this is the place to find out for sure.
