SF Current Example

If you want to understand the benefit from using SF Current Forecast Maps all you need to do is read this Sailinganarchy forum post:

Can you explain this one a little more? Sunday, during sarcoma cup, on the beat up to harding rock from the circle, one of the boats went all the way to blossom rock and then made a single tack to harding. Everyone else was hugging the south shore of angel island looking for relieve from the flood. Surprisingly (for me) that boat gained big time on the whole fleet, while I was expecting it would be suffering the effects of the flood. There seemed to be decent wind all across the bay, so I don't think they gained just because it might have been windier on the southern side.

And then look at the map this page would have given any competitor in planning their strategy. The race was on August 28, 2011 and although we don't know the exact time of this race, we know that the first race started at 11:00 so let us look at a time map for 12:00. You can pick any time and print the map, the conclusion will be the same, stay away from Angle Island, sail close to Blossom, just like the boat that made a big gain on the whole fleet.

If you put your mouse over the map below the image will change from the one recommended by SF Current that any racer could have gotten a full 2 weeks before the race to the one generated by SF-Ports based on the measured tide at the race start time.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
