We should have federal legislation requiring tugboat assist adequate to recover from complete loss of power and steering, through shipping channels that go under bridges supported by mid span support columns. The mechanism should be that if the Coast Guard catches you without a tug, the ship is permanently banned from the port under threat of seizure and repossession by the US federal government, or your vessel just gets immediately seized and held in port under bond.

Insurance providers insuring ships in US waters should also be required to permanently deny insurance coverage to vessels found to be out of compliance, though I doubt the insurance companies would want to play ball.
