About the presentation:
The presentation outlines a comprehensive set of sea trial experiments used a high-throughput test methodology to characterise the turning of a full-scale 8.5m custom-built powered catamaran test vessel. Five factors potentially influencing a catamaran's dynamic stability were considered, Beam, Deadweight, Vertical Centre of Gravity, Thrust, and Engine position. The experiments sought to create a baseline of data and then test each factor’s contribution to dynamic instability and identify (if any) interaction between the factors. The data from the experiments present an insight into the multi-factor relationships that impact the instability of a powered planning Catamaran. Despite the limitation to a single vessel length, the results give a predictive model and approach to improve catamaran design and safety.
