... and thank you for visiting my "private web site".
I was born and raised in Flanders - at the outskirts of the North Sea.
Later, I moved to Germany where I am currently working in the field of
high-speed optical data transmission.
Over the last twenty years, blue-water sailing has been one of my favourite leisure activities.
And while enjoying the modern unpretentious way-of-navigation on the seas, I became very fascinated by
the nautical skills in navigation and practical seamanship the ancient Sumerian, Phoenician
and Polynesian navigators must have had.
I also began to understand the exceptional nautical accomplishments of the Renaissance-time
On this background, particularly the history and practice of 'traditional' Celestial Navigation
(using a sextant, a Nautical Almanac and some pre-compiled Tables) have become special topics
of interest. So I started looking for information on these issues.
In the wake of this, in Sep 2000, I started this web project as my private
collection of the information related to maritime navigation I was able to find.
It has been growing since then and it is doomed to never be complete ...
About these Web Pages
My occupation with Celestial Navigation over the last
two decades was the primary reason why these web pages were originally created.
The purpose was to assemble the complete information needed for practical Celestial Navigation.
I especially intended to compile all the essential information for practising
Celestial Navigation in such a form that it can be performed without the
necessity of any on-board electronic resources such as calculators or computers.
To the best of my knowledge, in the early 2000 years this was
- and maybe still is - the first and only internet site, supplying all the information
needed for Celestial Navigation (Nautical Almanac, Interpolation Tables, Sextant Correction
Tables, Sight Reduction Tables, Worksheets and Instructions) from a single
source in a complete and consistent form.
And moreover it still is completely free of charge and free of advertisement!
In the meantime my original "celestial project" has now been integrated
in my "nautical web pages", which now also cover other aspects of navigation,
as well as technical and historical issues related to sailing.
I enjoyed compiling these web pages and I hope you may find something useful among the
different topics! But keep in mind that these pages have been collected to serve as my
private source of information for sailing related issues.
As a consequence you cannot expect to find a complete guide on the different topics covered here.
The available information is rather incomplete and severely biased to my personal interests.
Furthermore, no warranty can be given for the correctness of any of the supplied information
(see "Terms of Usage" below).
These web pages do not pretend to be a complete guide to
any of the available topics. Their principal purpose is to serve
as my personal source of information on sailing issues. I would of course
enjoy it very much if the information available from this site would
also be of practical use to other people.
But, please notice that there is no guarantee that all of the available information
is correct. Particularly much of the tabulated date for Celestial Navigation is generated
with computer programs, which may still contain some uncovered bugs.
If you find wrong data or false information, but also if you have found
something useful here, please feel free to send me your
feedback and comments.
