Are you suggesting calm lake waters all the way upstream? Lake or river, eddy

Kaput. Finito. Perdido. Fini. Done for.

Dave, this is not true. In your earlier post you showed that the area (and
hence wind torque) increase as it tips. But saying that this proves the ark
will tip is a one-sided equation.

The other side of the equation is the restoration force from the water. We
all know that as you tip a rectangular boat in the water then there is a
restoration torque from the water, because one side of the boat is being pushed
deeper than the opposite side. I did the calculations and it turns out that in a
50 mph wind broadside Alan Hill's boat will tip the ark a grand total of only
0.6 degrees. In a 100 mph wind it is 2.4 degrees. A boat like the one
described by Alan Hill will NOT tip over when broadside by winds of the magnitude
that he calculates.

So let's stop discussing the ark tipping. This is NOT a valid critique of
Alan's paper.
