Really guys, this is simple.
It was Newton that pointed out that all non-accelerating frames of reference are equivalent, and if the current is steady, then nothing has changed...
... except it looks different, since you are basically on a conveyor belt. When you begin to turn away, you apear to accelerate, but only with refference to the shoreline. If you where in the Gulf Stream you would need instruments to tell you there was a current (except for wave action--the waves are often spawned outside the current and have a non-current adjusted spacing).
Just an optical illusion.
Eddys and variable currents are a different matter.
