...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...

...Tobias Lorimer; Tom Allen Optimisation has become a necessary tool when designing competitive high-performance composite yachts. The inherently complex material characteristics of composite materials mean there must be careful consideration of laminate and structural design to withstand loading...

...Christopher D. Barry One problem for high performance yachts is to produce a light enough, strong enough structure. Modern fiberglass “composite” construction achieves this, but at substantial cost for the molds so fiberglass is expensive for limited construction. However, “composite...

...Cian Byrne; Thomas Dickson; Marin Lauber; Claudio Cairoli; Gabriel Weymouth Accurate modelling of the performance of a yacht in varying environmental conditions can significantly improve a yachts performance. However, a racing yacht is a highly complex multi-physics system meaning that real-time...

... benchmarks and databases in naval hydrodynamics, including aerodynamic phenomena on ships with the aim of evaluating the applicability of such benchmarks to sailing vessels. This paper also tends to estimate the relevance of proposing new benchmarks and their contributions to the yacht research community...

...A. Persson; L. Larsson; C. Finnsgård In this paper, an improved procedure for strongly coupled prediction of sailing yacht performance is developed. The procedure uses 3D RANS CFD to compute the hydrodynamic forces. When coupled to a rigid body motion solver and a sail force model, along...

...Fabio Fossati; Sara Muggiasca The aerodynamic behavior of a 48' yacht rig 3D scale model was characterized by means of wind tunnel tests. The experimental program, performed in the Politecnico di Milano Twisted Flow Wind Tunnel, allowed the aerodynamic forces to be characterized using forced motion...

This paper represents the first public release of the major changes and novelty in the standard, with a strong emphasis on high performance composite sailing yachts. The aim is to provide designers...

...Manolis Angelou; Kostas J. Spyrou In order to create capability for analyzing course instabilities of sailing yachts in waves, the authors have set up a mathematical model comprised of two major components. The first is an aerodynamic model focused on the calculation of the forces on the sails...
