design details like bulbous bow and appendages. These details may result up to 10% difference in the
total resistance. Adding more input parameters will increase the accuracy for special cases, however
without access to sufficient additional exemplars this may reduce generalisation of the method. The
method can be further developed with the access to new measurement data.
