At Pablo Creek we hit slack or run with the current every time, perfectly.
How? simple. We have an ap called "currents" on my android. Gives great info on tidal flow. We have found it to be quite accurate.
You can sail in the Indian River if conditions are right.
Make darn sure you account for all the markers heading past the inlet at St Augustine. VERY confusing.
Good points, Xort, especially the last one. There are three sets of markers there, the ICW, the inlet and the channel into Salt Run. ICW marker "60" appears to be an inlet marker because it seems to be too far towards the sea. It is critical to respect this marker, especially at low tides. All charts I have seen that have a magenta line place that line on the wrong side of the marker.
Talking to the Tow BoatUS guy he said he makes a living off that shoal marked by buoy "60".
