Sorry, you are wrong.  On the near side, we've got the water that's closer than
average to the moon, so there's stronger gravitational attraction, which pulls
things closer to the moon, and we get a high tide.  On the far side, there's
less gravitational attraction from the moon, so things are a bit further from
the moon than they would be if the gravitational attraction were uniform, so
we once again have a high tide.

hold me responsible for it, but my organization had nothing to do with it.
