Evaluation of trimaran side hull angles on forward resistance

Abstract

This project reflects the authors’ view on the influence of the side hulls rotation with respect to X and Z axis on trimaran’s total forward resistance. Even though the first modern trimaran was built decades ago, this domain is still new and full of unbeaten paths. One of the most important aspects in the design of this type of vessel is the hulls layout. This decision can influence the propulsive, seakeeping and manoeuvring capabilities of the vessel as well as the main deck layout. While there are plenty of studies which analyses the effect of the side hulls translation, with respect to X and Y axis, there is no information regarding the influence of the side hulls rotation on the vessel’s performance. Therefore, the main goal of this project is to get a first insight into the importance of this aspect.
