Abstract
There are several advantages associated with a Trimaran hull, which makes it a unique concept in comparison with
catamaran and monohull vessels. However, there is a limited understanding of trimaran motion responses and in
particular, the roll characteristics that may occur in oblique seas. The research undertaken in this paper intends to
develop a better understanding of the parameters influencing high-speed trimaran motions response in waves. A set
of experimental tests for two configurations of a 1.6 m high-speed displacement trimaran model was conducted in a
range of wave frequency, where a constant wave heading, and wave height is maintained. The results suggest that
the position of the outriggers has a considerable impact on a trimaran performance in oblique seas. The results from
this work lead to a better understanding of the parameters influencing the passenger comfort as well as optimising
fuel consumption.
