i'm sure you are right but it's interesting to explore the possibilities
is it not? I find it more interesting than guns and GWB (for example).

Nav,

Don't you think you are overstating the obvious? The Tide is a dynamic
action of water caused by the moon. The height of the Tide and the Tidal
flow are dependent on one another. The location of the rise in the Tide
is determined by the speed of the earths rotation and the revolving of
the moon. The height of the Tide determined by the Phase of the Moon.
The higher the Tide rise the greater the Tidal Flow

I hope this meets with your approval. I'm very sure we all have
overstated what Scott wanted to know about riding the Tide.

P/S Donal give him the full point. He gave the answer to the moving
tide, making a tide ride possible
