... and Feedforward Neural Networks — that rapidly predict aerodynamic performance with CFD-equivalent accuracy. These surrogates capture aerodynamic interactions across various WPS configurations, including unit number, deck arrangement, independent sail trim, hull characteristics, and wind conditions. While...

...Connor A. Pearson; Tom D. Allen; Mark A. Battley The phenomenon of slamming is often the critical design load for high-performance marine craft. Slamming involves the solid-fluid impact of a hull structure, resulting in large forces acting on the structure from the large volume of water displaced...

... for analysis on the impact of Rudder Rake Differential ( R D ) on overall performance, and predicting the optimal wind range for use of the light and heavy weather dagger boards on the AC50 Catamaran. The AC75 SVPP and DVPP were used to analyse the affect of hull shape and the main foils’ fixed angle-of-attack...

...Hannes Renzsch; Britton Ward . In this paper an approach to mimic the influence of appendages on the pressure distribution on a boat’s hull in RANS simulations is given. While, of course, the appendages could be modelled explicitly in the RANS simulation, this significantly increases the cell count...

... of Sailing Technology presents the very last insights of Prof. Masuyama into the sailing performance of the 470 Olympic class dinghy. ABSTRACT. The paper presents a Velocity Prediction Program (VPP) for the 470 dinghy. Starting from a description of the hull performance and sail performance, measured...

...A. H. Day; P. Cameron; S. Dai : This study examines the hydrodynamic performance of a high performance skiff hull using three different physical testing techniques which may be used in early stage design for assessment of the upright resistance of sailing vessels. The hull chosen as a benchmark...

... limited to means for restricted methods where computational resources and budgets are limited. Enhanced lifting line approaches are described for the wingsail and appendages. Windage is calculated from force coefficients and dynamic pressure while hull resistance is determined by means of a potential flow...

...Peter F. Hinrichsen Measurements of the inertia parameters (Gregory, 2006) of a keelboat hull using a bifilar suspension (Newman and Searle, 1951) are described. Bifilar yaw moment measurement normally entails accurate measurement of the length l and spacing 2 d of the suspension, and of T y...

The other component of the presented mathematical model refers to the hydrodynamic part and it is focused on handling the motions of the hull, with her appendages, in water. The hydrodynamic part is comprised of sub-models for hull reaction, hydrostatic...
