  A theoretical model of Soliton on Finite Background of a family of exact
solution of the nonlinear Schr\"{o}dinger equation for extreme wave generation
is discussed in this paper. Some characteristics and physical properties of
this solution are explained. The comparisons with experimental results from
MARIN and with the simulation result from nonlinear wave model HUBRIS are also
presented. The occurrence of phase singularity is observed, as predicted by the
theoretical model of Soliton on Finite Background.
