A fun site, Larry. When planning an instrument flight plan we used to use (some still do, but computers are working wonders for some) a "Flight Computer" that had a circular slide rule on one side and on the other a way to calculate drift and ground speed from known winds at a specific altitude depending on direction of travel and True Air Speed. I was looking for my old Flight Computer = E6B or Whiz Wheel, as we called it, and want to play with it to see if the same could be calculated for a kayak given known wind conditions and currents. Has anyone ever done something like this? There are some excellent chapters in "Fundamentals of Kayak Navigation" by David Burch, which provide the underlying formula for the calculations. This doesn't provide a field expedient means for calculating drift correction or Velocity Made Good in order to come up with Course to Steer and Estimated Speed to get to ETE or ETA when planning. He does provide some means for adjusting course to compensate for currents and/or winds using piloting. Of course, there is always a GPS, right?
