Under the International Collision Rules & the Maritime Rules Part 22 Collision Prevention, which is the NZ rule & which is the applicable law here, the only defined methods for assessing whether risk of collision exists are the use of compass bearings or radar.
Before specifying compass & radar however, the rules specify that “all available means” must be used. It is important to note that there is no limitation on the methods to be used, in any NZ or International rules.
Extracts from Maritime Rules Part 22 Collision Prevention
“22.7 Risk of collision
1: Every vessel must use all available means appropriate to the prevailing circumstances & conditions to determine if risk of collision exists. If there is any doubt, such risk must be considered to exist.”
It is important to note that use of all available means includes using radar, AIS & anything else available, without limitation.
In general, ‘constant compass, decreasing distance’ means a risk of collision exists, as shown in the sketch. The ships 1 & 2 in the sketch are following paths along similar triangles. Any movement of the relative bearing indicates that the ships would not reach collision point at the same time, therefore there would be no collision. For a collision to occur there must be a decreasing distance & a constant compass bearing.
