161.13—VTS Special Area operating requirements.
         The following operating requirements apply within a VTS Special Area:
    
    
        
        (a) 
         A VTS User shall, if towing astern, do so with as short a hawser as safety and good seamanship permits.
    
    
    
    
        
        (3) 
         Not meet, cross, or overtake any other VMRS User in the area without prior approval of the VTS; and
    
    
        
        (4) 
         Before meeting, crossing, or overtaking any other VMRS User in the area, communicate on the designated vessel bridge-to-bridge radiotelephone frequency, intended navigation movements, and any other information necessary in order to make safe passing arrangements. This requirement does not relieve a vessel of any duty prescribed by the International Regulations for Prevention of Collisions at Sea, 1972 (72 COLREGS) or the Inland Navigation Rules.
