8.0 Operations after dark
All after dark operations should be carried out with extreme caution.
No solo operation of departmental vessels is permitted. Limited
night vision may give a false impression of the water conditions
and the normal signs associated with a weather change will not
be visible. In addition, the risks associated with working close
to shore, submerged reefs or working in strong currents will be
increased due to limited visibility.
The operator must be familiar with the area in daylight hours
before attempting to work there after dark and must plan how to
use any navigational beacons. Prior knowledge of their positions
will make night navigation easier.
All boats must follow normal operating procedures and be equipped
as indicated above. In addition the following must be carried/used:
- Navigational lights as specified for class of boat
- VHF radio
- Each crew member must carry a light source ("Cyalume" stick,
- Compass and, if available, chart of the area
- If operations include diving, the appropriate "Diver Below" lights
must be exhibited
8.1 Restrictions applying to areas of use for after dark operations
- Both dinghy and runabout classes of boat may operate in
- Operations at night may only be carried out when lighted
navigation aids are visible, or when temporary lighted marks
have been established.
- Runabout class vessels only may be used in this area
- A GPS/Plotter is strongly recommended when operating in
All diving from small boats at night must comply with the rules
stated in the University of Otago Diving CoP.
Due to the additional
difficulties associated with mounting a night time search it
is doubly important that the rules concerning
shore communication, observance of ETAs and intentions boards
are strictly adhered to.
