Development of a Quantitative Method for the Assessment of Historic Ship Performance
The evolution of ships through time is not linear. There is little quantitative evidence for how ship design has been affected by the political, social and economic environment. This paper develops a method of providing quantitative data to support or oppose established theories using initial ship design tools, tested to ensure that they are suitable for use with historic ships. This is achieved using a Velocity Prediction Program (VPP), which, through balancing aerodynamic and hydrodynamic forces, can be used to calculate potential ship speeds. Considering the VPP output in conjunction with changing hull parameters over time, it is possible to see how ship design and performance evolved. The Holtrop and Mennen method for estimating hull resistance is commonly applied to historic ships. This paper shows, through comparison with Computational Fluid Dynamics (CFD), that this method is suitable. For sailing vessels, hydrodynamic side force also needs to be considered. This is calculated by isolating the lateral force component of maneuvering equations developed by Inoue and Kijima. CFD results show that this is a suitable estimation, as well as highlighting a simple geometric approximation for added resistance at small angles of leeway. The ability to estimate historic ship speed allows quantitative evidence to be generated where it was previously lacking. The application of naval architecture within archaeology allows for a new perspective on the evolution of ships and hence our understanding of ship design.
