Is this program available on the web somewhere?

It's the original version of Tides. An updated version was released but
without the necessary data for the United Kingdom because the Hydrographic
Office reckoned they had the copyright to it.

But it was on the previous version?

My program works well and the predictions it produces are within 10-15
minutes of those of the Hydrographer.

It's the heights, rather than the times I'm most interested in.

It's no longer available on the web but I'd be happy to put a copy on my
website so that you could download it.

That would be great.

BTW, will it run on any version of Windows?
