WAIT.........We're forgetting something. What if he has a 35mph current, and SPEEDWAX?
Cant forget to factor that in, can we?

The other factor that was mentioned earlier that could have a definate effect is wind. Now, are we talking into the wind or with. If there is wind. Is it natural or man made. If the wind is man made, was the man facing forward or towards the stern. cause if he was facing the stern, this could have a detrimental effect on speed. Not to mention a foul odor that could be smelled by the driver.

If someone was standing on the bank of the river shooting you with a radar, I guarantee you would be faster going down river than up. It's the same principal with GPS.
When I'm just floating down river with the boat off the GPS will read at least 4 mph. The reason it doesn't read 6 mph is that the water is travelling a little faster that the boat.
