simeple waves difined as following equaiton.
\begin{equation} y(x) = A\sin(kx-\omega t) \label{wave} \end{equation}where, \(k\) is wave number, \( \omega\) is angular frequency
Lewis form which is a simple hull form expression is applied. Lewis forms represent the hull shape as a linear mapping to a circle. \begin{equation} x+i y = M { \zeta + a_1/ \zeta + a_3/ \zeta ^{3}} \end{equation} \begin{equation} \zeta = \sin{ \theta} + i \cos{ \theta} \end{equation}
