... The aim of the this paper is to develop an accurate and robust six degrees of freedom stationary VPP model applied to a high-performance sailing yacht. The model is set up to assist NC Raceboats with the VPP based hydrofoil design, considering the sailing performance in three modes: archimedean...

... fuel cost (direct or though emission penalties) and environmental awareness (intrinsic or driven by customer demands). In this paper differences between the design requirements in the commercial market and the pleasure or racing yacht industry are discussed and enhancements to the existing design tools...

... Optimisation has established itself as a necessary tool when designing competitive high-performance yachts. The inherently complex material characteristics of composite materials mean there must be careful consideration of the effects of laminate design to meet loading and efficiency demands...

... One problem for high performance yachts is to produce a light enough, strong enough structure. This is possible with modern fiberglass “composite” construction, but at substantial cost to produce the molds. Thus, composites are expensive for limited construction. However, the term “composite...

... Interest in foil-assisted monohulls continues to increase. Indicative of this trend is the success of the current IMOCA60 class, the proliferation of new or modified foil-assisted dinghies, performance luxury yachts, as well as race boats, including the novel America’s Cup Class (AC75...

... This paper describes insights into keel and rigging loads obtained through a data acquisition system fitted on the fleet of Volvo 65 yachts during the 2014-2015 Volvo Ocean Race. In the first part keel fin stress spectra are derived from traces of canting keel ram pressures and keel angle...

... Yacht races are won by good sailors racing fast boats. A good skipper takes decisions at key moments of the race based on the anticipated wind behavior and on his position on the racing area and with respect to the competitors. His aim is generally to complete the race before all his opponents...
