Abstract [en]

This master thesis is concerned with the design and optimisation of a dynamic velocity prediction programmefor high performance sailing yachts. The simulator uses response surfaces methods, maximising the computationaleciency. Insights are given on dynamic theoretical aspects and models are discussed with respect to thestudied ships, 100 feet oshore racing trimarans. The consistency of the currently used models is assessed, andfeasible solutions and methods are proposed and implemented as solutions to the identied defaults.The simulator is subsequently used on a concrete case with the objective of assessing the eects of precise geometricalfeatures of appendages (rudders, foils and boards) on the ship dynamical stability properties. Area, extension,cant angle and tip-shaft angle in particular are studied. Tests cases are developed and multi-parametersstudies carried out. Dynamic results are compared to usual static stability criteria. Simulations show someinconsistencies of dynamic responses with the behaviour expected from the static criteria. Such processes allowbetter understanding of the design and scantling of the studied appendages.
