Description
1. The impact of principal dimension variations on the hydrodynamic performance of high-speed trimarans (HST) is examined. 2. A symmetric trimaran series is created using the Wigley mathematical hull form for the main and side hulls, allowing for varied proportions while keeping constant displacement. 3. The models are evaluated in deep calm water across a range of Froude numbers (F_(n_L)) from 0.1 to 1.0 using a two-dimensional modelling approach. 4. Wave-making resistance is calculated using the Slender Body Method (SBM), and friction resistances are supplemented by the ITTC ’57 turbulence line. 5. A Design of Experiments (DoE) procedure is implemented to select trimaran designs for deeper analysis in future studies. 6. A computer macro, Tri-PD©, has been developed for interaction with an offset-based model generator (Maxsurf Modeler®) and a resistance calculator (Maxsurf Resistance®). 7. The numerical results generated by Tri-PD© are validated against existing analytical, numerical, and experimental data to confirm their accuracy. 8. The study offers design recommendations, highlighting the importance of dimensional variations in improving trimaran design and performance.
