But in the meantime the paper had already been subject
to rigorous updates and corrections, and that work
will be continued, based on further in-depth studies
and clarifications of details.
And in re-considering my analysis of motions around
our galaxy I noticed, that the 'dark matter' is only 'required'
to compensate for a conceptional mistake. In view
of the widely extended mass distributions of galaxies
Newton's gravity law cannot be applied in the integral,
inverse square format.
Following the foregoing analyses of my axiomatic model
one of my results has mislead me to confuse dark matter
and the very large body of ponderable matter, alias black
hole, discovered by Reinhard Genzel and honoured
by the Nobel Prize for Physics 2020.
My resulting arguments have been deleted and I modestly
ask for apology.

they are doomed to fail.

My continued modest invitation

According to my own repeated experience, in Germany,
different from England, critical remarks tend to be felt
as personal offence, though 'only' beliefs, maybe cherished
life long, are questioned and may need to be abandoned.
As known from well understood historical examples, the
opposition usually is very strong and takes generations.

The paper is essentially a continuation of Bernard Caldwell's
history of ship theory in his chapter on Brunel's three great ships,
a contribution to 'The works of Isambard Kingdom Brunel',
an engineering appreciation edited by sir Alfred Pugyley, 1976.
For my taste too little is known of the development ship ship theory
and its implicationns. David Moore passed away before his history of
ship model basins, to be based on his large collection of documents,
was even started .
Quasi-steady model trial 1986
The following set of ten Mathcad programs concerns the
- Final evaluation of my model test of 1986
conducted as feasibility test for the quasi-propulsion tests with the
reseach vessel METEOR in the Arctic Sea in November 1988.
As it turned out, the conceptual and mathematical problems were
much more involved than expected. Thus, apart of the evaluation
of the METEOR tasts and large projects on the evaluation
of water ways, it took me another thirty years finally to solve
all the problems faced. Details are to be found in an additional

Last corrections and updates: 2021.02.15
My work on 'ideal models of real systems' has been disrupted
once and again by more urgent responses concerning the theories
of ship powering trials and monitoring and of cosmology.
The latest of such disruptions is the following letter concerning
- Hegels_Theorien_etc.
But as a matter of fact, all the disruptions turned out to contribute
to the clarification of my thoughts.
Last corrections and updates: 2020.03.17
The short question: Why do ideal laws apply in the real world?
is still keeping philosophers, scientists and engineers wondering,
although the answer is known since more than 2000 years ago,
when Socrates, in Plato's 'Politeia', told his parable of the
prisoners in the cavern and since Kant's Copernican turn, since
he realised, what humans can possibly know about
das Ding an sich.
During work on a paper concerning the answer to that question
a number of details required special attention and elaborations,
in more detail than could be accomodated in appendices.
And diving deeper and deeper into the pertinent literature I
disrupted that project, realising that it was far too ambitious.
But of general interest may be the
- Draft summary and conclusions

My re-evaluation of the REGAL trial of 2015

Report on the following two entries
Work on my two recent exercises on trials, documented in the
following two sections, has triggered my
- Correspondence on the REGAL trial
with Dr. Klaus Wagner and my draft
- Report on recent work on trials
to the forthcoming Meeting of the STG Committee on 'Ship
Hydrodynamcs', at VWS in Berlin on November 08.
As most of my work on trials has been written in English,
the report has been written in English as well.

Preparing for the analysis of the raw data the rational analysis
of the REGAL trial has been scrutinized and minor mistakes
and the notation have been cleared up.
Last update and additions: 2020.03.10
The purpose of the exercise performed, the
- REGAL_trial rationally re-analysed,
originally conceived as contribution to MARIN's JIP JoRes, is to
demonstrate once again, that the inherent deficiencies of the
standardised STAimo procedure can be avoided by the transparent
rational evaluation.
That method, repeatedly applied in very delicate cases, is solely based
on only four simple conventions, constituting an acceptable, highly
aggregate model, sufficient to analyse the performance in the limited
range of hull advance ratios covered by the few, 'hopefully' steady
states during the trial under scrutiny.
The few parameters of the model conceived can reliably be identified
from the data acquired during the trial, without reference to doubtful
prior data of any kind. In response to misconceptions met in discussions
it is explicitly noted, that the problem solved is a conceptual problem,
the subsequent identification of parameters is a necessary, in the
present case rather trivial step.
In the meantime I have been informed, that as a private person I cannot
take part in the project with the non-sensical title 'Joint Research',
claimed to provide a broad forum for the validation of ship powering
predictions.

Having finally sorted out basic conceptual and numerical mistakes
I have 'conclusively' analysed the data of my quasi-steady 'model'
powering test in terms of a 'model test' and a of simulated 'ship trial'
and accordingly up-dated the former published defective worksheets.
The evaluation of the quasi-steady 'model' powering test of only
two minutes duration in terms of a 'model test' shows, that no
references to bare hull towing and propeller open water tests are
necessary, thus drastically reducing the costs of model tesing.
The evaluation in terms of a 'ship trial', i. e. without reference
to thrust data, not available on full scale, requires an additional
convention. Missing data cannot be sucked from the thumb!
Paradigmatically reference to the propeller open water jet efficiency
has been shown to serve the purpose. The necesssary data do not
need to be obtained by model propeller open water tests, but may
be obtained by CFD methods, preferably at ship scale.
But it took further in-depth thinking to notice, that the unsatisfactory
reference to open water data is not necessary. The data acquired permit
to identify the propeller jet efficiency as demonstrated in the files
mod_6_ prop and mod_9_trial up-dated accordingly.

not limited to the

And I add a vote of
- Thanks to Daniel Wiens,
who as a student of numerical mathematics worked at Voith Marine
on my approach. He noticed, that my early naive attempts, to come
up with a definite solution of my crudely defined, 'highly' non-linear
problem, were doomed to fail in the presence of infinitely many
solutions.
Only after solving remaining conceptual problems I succeeded to
arrive at the intellectually and numerically satisfactory solution
of my 'still' non-linear problem, now published and replacing all
earlier heuristical 'solutions', though acceptable, but suffering
from defective arguments and procedures in various ways.

In response to my revision 6 I have received the following detailed
remarks, questions and proposals by Dr. Wagner,

My answer, originally intended just to summarise the related e-mails
we had exchanged before, resulted in further considerable corrections
and clarifications of the fundamentals. Re-publication of those files
and of my answer to Dr. Wagner have been pending for some time.
But in the meantime the following worksheets
- Numerical routines developed
- Partial efficiencies identified: model test
- Traditional vs. rational results: model test
- Partial efficiencies identified: 'ship' trial
have rigorously been revised and reached a state of maturity. Mistakes,
more or less serious, are taken care of as soon as detected. Hence do not
