The whole "There ought to be a law" mentality aggravates me, we already have so many rules in our world that it is suffocating. Rules don't stop accidents, if it did then the USCG who go by the Collregs, would have been following the rules regarding,"Safe speed." And the rule
about "Proper lookout." And the one about maneuvering in restricted visibility. Which until recently the USCG did not consider darkness "Restricted visibility". The people responsible for the accident will carry that burden the rest of their lives, as will the survivors. Nothing will be solved
by imposing a bunch of new rules for the rest of us to be following. If you don't use good judgment while underway, then no rule
will change that reality. If you don't care then a posted speed limit will not change that either, so all that ends up happening is the rest of us have one more regulation we have to be ruled by, there are more than enough regulations
in this world thank you very much.
