Maritime Navigation using Excel

Welcome to our website


Flag GaffMaritime Navigation using Excel is a collection of tools and a handbook of formulae for students and, of course, for watchkeeping officers, but not only.

In addition, represents an alternative to modern maritime navigation devices, such as GPS, ECDIS, and so on.

If you want to deepen the knowledge of these topics, then you should consult other additional sources.

The blog posts contain MS Excel 365 files, so that some features may not work properly on older versions of Excel.

For safety reasons, the files are protected, to not being changed accidentally or inadvertently.

All of them can be downloaded for free and can be used offline.

Also contain various examples that can be deleted and edited with your data.

The files can be used on any device (i.e., desktop, laptop, tablet, smartphone, etc.), on any operating system (i.e., Windows, iOS, Ubuntu, Android, etc.), and with any office application (i.e., MS Office, LibreOffice, WPS Office, etc.).

Do not hesitate to contact me for any questions and, also, I wait any suggestion from you.


The author express his special thanks to Rector I. Apostol and to the professors M. Deboveanu, C. Duma, N. Istrate and G. Panait, the teachers that I had in the navy school.

I very much appreciate the encouragement and friendly assistance given to me.

I’m also grateful to G. I. Balaban, M. Chirita and V. Pavica, the authors of the books used in school and in this website.

My final thanks go to my patient and understanding wife, Nicol, for all her assistance since I started work at this website.

Frankly, she knows MS Excel much better than me.

Fair Wind!
