Since the introduction of the resistance calculation for yachts based on the results of the original Delft Systematic Yacht Hull Series (DSYHS), as presented by Gerritsma et.al in 1979, 1985 and 1992, considerable changes have taken place in the design of both the shape and size of the appendages, i.e. keel and rudder. For the sake of consistency the original DSYHS was tested with one and the same set of appendages for all models, necessary for the heeled and yawed tests, which in design reflected the standards of the mid seventies for a hull like the Parent Model No. 1. This study tries to shed some light on the subject by reporting on a number of model experiments and calculations carried out to define the resistance of four different appendages under two different hulls.
