David Flater (who is author of xtide, the program I use to produce this data) provides the following disclaimer, behind which I firmly stand:

Do not rely on the output of this program for decisions that can result in harm to anyone or anything. Really. I mean it.

Agencies like NOAA exist because there is a need for certifiably correct tide predictions. Please do not rely on XTide if you need guaranteed results. There is no way I can get certified data on a zero budget. I rely on users like you to tell me when something is wrong. Please continue to do so.
