AMSA Marine Notice

In accordance with the Collision Regulations, ‘every vessel shall at all times maintain a proper lookout by sight and hearing as well as by all available means appropriate in the prevailing conditions to make a full appraisal of the situation and risk of collision’ (Rule 5). The Collision Regulations are implemented in Australia through the Navigation Act 2012 (s175).

Specific requirements for maintaining bridge visibility are set out in International Convention for the Safety of Life at Sea (SOLAS), 1974 Chapter V Regulation 22, which in Australia is implemented through Marine Order 21 (Safety and emergency arrangements) 2016).

Bridge visibility that does not meet the requirements of SOLAS significantly impedes safe navigation, bridge watchkeeping and maintaining a proper lookout. All of which are essential in the detection of vessels (particularly small and at close range), detecting craft or persons in distress, making a full appraisal of the situation and the risk of collision, and avoiding collision and stranding.
