Disclaimer
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 don't 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.
