Preliminary computation of yacht resistance components using Delft series

Abstract

The evaluation of the yacht resistance components in the initial design stage raises an important problem. The present paper deals with the results obtained on the basis of an inhouse computer code. The residuary resistance was determined by means of empirical relations developed from the Delft series, both in the low speed and high speed range. Also, the frictional resistance, heel resistance and aerodynamic resistance components were estimated with typical relations provided in the scientific references. The computer code may be used to perform the resistance and powering estimation in the initial yacht design.
