1. A collision avoidance method for a water-based vessel, comprising:
obtaining real time data relating to a path of two or more vessels;
identifying a collision risk between the two or more vessels;
determining if the collision risk is above a predetermined threshold;
when the collision risk is above the predetermined threshold, determining one or more collision avoidance manoeuvres by comparing the real-time data with historical navigational data corresponding to the real time data;
wherein the determining of the one or more collision avoidance manoeuvres is provided by a model having an input of the real-time data and an output of the one or more collision avoidance manoeuvres, and the outputs are provided by model parameters defined using the historical navigation data in which a historic collision risk between two historic vessels reduces;
wherein the model is an artificial neural network or polynomial expression; and
providing the one or more collision avoidance manoeuvres to an operator of one of two or more vessels.
