Comparison Mr Tides - EPSHOM in France - FF44 - July 6, 2005
Hi everybody,
A large comparison between Mr Tides and the french hydrographic service (SHOM) for hours and heights of tides in different harbours of the Channel and Biscay coasts comes as follow :
- For all locations :
Max difference hours : +/- 6 minutes
Max difference heigths: +/- 10 cm
- Warning - Saint-Nazaire :
A large difference of heights : 40 to 50 cm more in Mr Tides than SHOM.
The reason is that, in 2001, the chart datum of the area was changed up to 30 cm.
This probably explains this great difference.

Thanks for the information, I'll take a look at that station and see what I can do. Unfortunately the latest and greatest harmonics for France are unavailable due to copywrite problems with the British, so updates don't make it into the database anymore. Sigh.
