In the following
reports I have documented my work. It is work in progress!

- New Design Process Automation for Sailing
an update of the paper that I presented in Auckland 2006. The changes
are in the VPP, the optimizer is still up to date. The reason
the changes is the new insight in the prediction of the hydrodynamic
Loads for the Keel of a Sailing Yacht
This paper was published in the RINA

This is a report in German
about my visit to the Yacht Research Unit at the Kiel University. It
describes the circulating water channel.
Is There a Correlation Line for Hydrofoil
This paper discusses the prediction of the viscous drag of
keel and rudder in a VPP.
Factors that Trigger the Transition to Turbulent Flow on the Keel of a
The turbulence level in the ocean and its
influence on the transition of the boundary layer are investigated.
Influence of Sand Grain Strips on
Boundary Layer Transition in the Towing Tank
The equations in this report are a prerequisite for the
calculation of the viscous resistance of the DSYHS-models in
the towing tank.
Resistance of the Inui S-201 Hull
Resistance of the Delft-372 Hull
These towing tank tests offer an additional and reliable
for the validation of regression methods for resistance predictions.

Why am I not publishing in
The initial versions of the first two papers in this list were
published in refereed journals resp. proceedings.
The result was really disappointing, I got no feedback at all.
These papers are meanwhile hidden in very expensive CDs and are not
searchable by Google.
For the reports that I published on my web-site instead, I got a
tremendous and very helpful feedback.
