Delft Systematic Yacht Hull Series Measurement Data
These files contain all measurement data in calm water of the Delft Systematic Yacht Hull Series (DSYHS). Results are given at full scale (extrapolated values) and at model scale.
All measurements were carried out in the large towing tank of the Ship Hydromechanics Laboratory of the Delft University of Technology. The main dimensions of this towing tank are: Length=145m, Width=4.2m, Waterdepth= about 2.3m.
The last sheet in the Excel sheet gives an explanation of mentioned forces, angles and motions.
All data is already corrected for the extra parasitic drag of the turbulence stimulators which were used on hulls and appendages.
Note that every sheet contains all available data of that specific 'Sysser'-model. Not all models were tested with keel and rudder.
Further information and a figure of the standard test setup are given in publication: ''Report 1175-P, Keuning, J.A., Approximation of the hydrodynamic forces on a sailing yacht''
