...Malo Pocheau; Olivier Le Maître; Renaud Bañuls Static Velocity Prediction Programs (VPP) are standard tools in sailing yachts’ design and performance assessment. Predicting the maximal steady velocity of a yacht involves resolving constrained optimization problems. These problems have a prohibitive...

...Michele Francesco Melis; Heikki Hansen; Martin Fischer; Moustafa Abdel-Maksoud The aim of this paper is to develop an accurate and robust six degrees of freedom stationary velocity prediction program (VPP) applied to a high-performance sailing yacht. The model is set up to assist NC Raceboats...

... performance prediction tools are always semi-empirical, leaving significant room for improvement. In this paper we first use unsupervised machine learning to analyse full-scale yacht performance data. The widely documented ORC VPP (ORC, 2015) and the commercial Windesign VPP are compared to the data across...

... a comprehensive design campaign to answer the two questions. The campaign includes a newly developed Velocity Prediction Program (VPP) for foiling/non-foiling conditions, a wind tunnel test of sail aerodynamics, a towing tank test of hull hydrodynamics and a large number of numerical predictions of foil...
