This paper describes the results of a survey performed by the authors to assess how hydro/meteo conditions are presently modelled in ship manoeuvring simulators. While mathematical models for the manoeuvring behaviour of ships are well documented in literature, an overview concerning hydro/meteo modelling did not exist yet, despite the crucial role of this aspect on the global level of realism which could be achieved in manoeuvring simulations. A questionnaire regarding current, waves, wind and water levels was therefore sent to a large list of simulator developers and users, with the explicit aim to compile the results in a research paper. The received answers were thoroughly analysed and are summarized in this paper as an overview of the state of the art in hydro/meteo data for ship simulators at the time of writing. All the results are published in an anonymous form to guarantee a high discretion level to all parties who answered the survey. The information which is publicly summarized in this paper could benefit the whole community of ship simulator users and developers by making everyone more aware of the present common practices, while also fixing a starting point for future research and improvements.
