The Recreational Craft Platform (RCP, Norwegian: Fritidsbåtplattformen) is being developed to collect and merge available data on recreational craft accidents and thereby enable stakeholders to actively take measures to achieve the vision. The Norwegian Maritime Authority (NMA) will be the owner of the platform, using it to analyse the causes and risks associated with recreational craft, and to identify and evaluate risk reducing measures to reduce the number of accidents significantly. This paper presents the risk model for recreational craft accidents, developed together with the NMA that will support NMA's and their partners work to achieve these goals. The risk model was developed following NMA's existing risk modelling approach, with focus on the accident frequency of motorboats, sailing boats and personal watercraft. The model will be employed to assess effectiveness of measure and visualizing the contributing factors within the RCP.
