Tide Calculations and NOAA Tide Stations
Greetings. I have a Garmin 276c and appreciate and use the tide chart / solunar tables application. I have a few questions though...... The closest tide station available for reference on the unit/chip is 85 miles away. There is a registered NOAA tide station 150 yards from my house, but it is not available as a reference station on my unit/chip. Does the unit calculate the estimated tides from my location via GPS coordinate relative to the nearest station? Or does it give me the tidal info as they are calculated at the tide station 85 miles away? Also, is there a way to add Tide Stations to the list on the unit/chip or do I have to wait for an update to the charts?
