During restricted-visibility conditions, conduct a
moderately fast search without binoculars, but have
them within reach in case the fog suddenly lifts.
During restricted visibility, all ships continually
sound fog signals in accordance with Navigation Rules,
International - Inland. (See figure 18.) Most contacts
will have to be reported by hearing prior to the actual
sighting. Sounds that might be heard and must be
reported are bell and whistle buoys, small craft motors,
fog signals, wash of water on another ship's hull, and
any other unusual sounds. You must constantly be alert
and concentrate on the job at hand to hear these
Report sound signals using the following format.
1. WHAT IS HEARD: One prolonged blast, a
rapid ringing bell, two short whistles, and so forth.
