Why should you BUY software when it is available all over the world for NOTHING!!!
I have found a great prog call Jtides that would be all you would ever need BUT does not include UK data - it has everywhere else in the WORLD bar the Uk - WHY???
Here is what they say
# Note about UK Coverage
* In April 2002, the UK Hydrographic Office ordered the removal of all UK tidal data from JTides and all other free tidal prediction programs. The fact that this is a free program, created in the public interest, has had no effect on their zeal to collect nonexistent copyright fees. The fact that this decision will decrease the safety of sailing in the UK has not swayed them in the slightest.
I mention this because the absence of UK tidal data is one of the most common inquiries about JTides. I am powerless to shape the thinking of the bureaucrats in the UK Hydrographic office, and I imagine Lord Nelson is shifting uncomfortably in his grave!!!
So in other words the UK Hydrographic Office are nothing but SCUM!!!
