I keep my boat
on the St John's river in Fl but have to traverse through Jacksonville
Fl to get either to the Atlantic or the ICW
and/or back to my marina. Although I pay attention to tides, it appears to be a hit or miss affair catching both tide and current
going in the right direction. My question is 1) whether there is either a chart one can use to coordinate tide and current
, or 2) does anyone know of some type of algorithm to coordinate tide and current.
