    Thanks Leo!
    The scatter in the resistance measurements between different towing tanks is pretty much disappointing. It seems that the possible error is meanwhile equivalent to the accuracy of the CFD-results. Interesting development!
    The report about the turbulence stimulation might give an explanation for the scatter in the measurements.

    There are several disappointing aspects of the world-wide testing program,
    however, it was probably the largest ever co-operative exercise in ship
    hydrodynamics. The ITTC will continue to gather results and hopefully
    continue tests at more facilities.

    It certainly showed up how difficult it is to run double-blind tests with 40
    different towing tanks in many different countries.
    Imagine the errors and inaccuracies if the CFD codes were evaluated double-
    blind, and/or with no prior access to experimental results!

    I'm just slowly ploughing through it now myself...interesting reading indeed!

    Cheers for the link :p
