My Tuamotu Tidal Guestimator has been updated for 2011 tidal information and is available for download on our Google Docs Page.
Special thanks to Sherry McCampbell from Soggy Paws for all her help reformatting the program and refining the user interface.
We both found the program very helpful for predicting the currents through the passes of the Tuamotus and with a little experience were able to predict slack tide quite reliably before ever even going to a particular atoll. Very helpful for passage planning so you time your arrival correctly and avoid the scary and dangerous situation of approaching a pass with 7+ knots of current rushing out.
If you do find the program helpful to your cruising, please click the donate button below and buy me a beer. If you have any questions, feel free to email me at email@example.com and I will try to help you out.
