answer to wiki answers The water is not always the same on two sides if a boat?

There is a Finnish proverb. "The water is the same on both sides of the boat" It is wrong!
Yes. As a pearl diver I was sleeping in a small boat on the barrier reef and the tide was going out at a fair rate of knots and at a point from the reef the water went under the boat and disappeared into the depths. There was a line where this happened and not being anchored we found this phenomena as the boat drifted to it.
