3 CONCLUSIONS

Hull form of a passenger catamaran has been derived to meet economical and natural requirements for
operation in the planned routes. The hull forms and their hydrodynamic characteristics both in deep and
shallow waters are investigated through model experiments and numerical simulations to determine its
practical applicability. It is found that the approach in which numerical and experimental methods
incorporating is beneficial in the initial design stage of a catamaran. The hull form of the catamaran
obtained with the approach seems to show relatively good performances.
