Well, I have about 500 lines of C that uses a 37 coefficient set to perform tide prediction calculations but it's not code I can release to the public domain (I don't have ownership of it) and I'm not sure I could legally derive a Perl equivalent from it. However, it's pretty much solid calculation so the equivalent Perl wouldn't be a heck of a lot smaller. You can gauge from that the size of the coding task. Oh, and I don't know how compatible that set of parameters may be with publicly available tide parameter sets so the whole thing could be a complete waste of time in any case.

To be of any practical use a tide calculation module would need to use a set of parameters for which data is publicly available. It's about 10 years since I worked on any of this stuff so maybe things are different now, but then the data was considered valuable and was hard to come by. Because of the potential difficulty in getting data I'd think there would be little call for such a module in CPAN. My involvement in such calculations has long since passed so I have no particular current interest in creating such a module.

True laziness is hard work
