    Respectfully, my copy of the (US) Navigation Rules does not mention
    anything about their "not applying to vessels in fog so dense that one
    cannot be seen from the other."  Rule 6 (both International and US Inland)
    clearly requires vessels to "at all times proceed at a safe speed so that
    she can take proper and effective action to avoid collision..."  To me this
    says that if the fog is so thick two vessels can't see each other, they are
    both obligated to slow down or stop!
    
    BTW, I find myself joining others in wondering exactly how this is going to
    work with the new 40-knot Portland-to-Yarmouth ferry.
