These movies were taken while we were bucking an outgoing tide at the
entrance to the Cape Cod Canal. We were idling which usually gives us
around 3 knots. My GPS was indicating 1 to 2 knots SOG but in this
case I believe it was actually reporting our backwards progress.
Notice that the waves are overtaking us.

Help me out here.

You were heading into an outgoing tide at the Canal?

Because that doesn't make any sense.

Not sure what you're getting at, is this a trick question ???

We were heading "up" Buzzards bay or "east" in terms of the canal in the Hog
Island/Onset bay area approaching the west end of the canal a around 4:30PM
on 7/7. The tide charts for that day show High Tide at the railroad bridge
as 2:42PM and show the current turning west at 3:28PM.

So here is a crappy ASCII art diagram of our situation:

I understood what you posted - the video shows something entirely
different.

If you look at the video, you are relatively motionless as compared to
the shore.

The waves are coming at you and passing you from the stern.

Unless it's some kind of optical delusion that I can't parse. :)
