Abstract:
This thesis describes a study about the trimaran ship and the frictional
resistance analysis with different side hull ratio and position. A trimaran hull form
consists of long slender main hull and two relatively small side hulls. There are a lot
of research papers available that investigated the advantages of large trimaran
configurations for future cargo ships and alternative frigate/destroyer size warships.
There are also several trimaran designs being investigated, which claim both high
speed and high hull efficiency. In this study, the author focus on how to reduce the
trimaran ship resistance in calm water. In order to achieve that goal, the suitable
layout for trimaran ship will be investigate. The layout for trimaran ship are the length
of side hulls to the center hull for trimaran ship, the longitudinal position of the side
hulls and the distance between the side hulls with the center hull.
