Quote:Currents are provided on charts and tidal streams booklets by the french hydrographic office. Stations provide only tidal datas (hours and heights).
But how do other tidal programs calculate the currents for these regions? Do they just interpolate the data?
Many PC nav related programs show currents arrows. MaxSea does have it's own data, but many non-expensive progs just have the feature to show the currents. So there must be some data available.
Even on my old Psion 5MX Pro pocket computer I had the ability to not only show the actual tide values for any station in France but it did also show current directions and strength.
