Add to that the fact that as the boat heels the weight on the rail
is also getting closer to the center of mass for the boat
I'd guess that at 63 deg heel the rail is likely dead overtop of
the center of mass - and thereby providing zero counterbalance.

I guess don't follow the adage of 10 aloft equals a man on the
rail.
While the mast to rail distance is a factor of 10, there is a
sin(heel) factor for the aloft weight whereas it is a cos(heel)
for the rail. That is, at zero heel any weight aloft is equal
to zero on the rail. At 20 degrees heel, 10 lbs aloft is
approximately 36 lbs on the rail. The heel would need to be 63
degrees before the 10 lbs aloft is equivalent to 200 lbs on the
rail. Also, since all of the weight aloft is not at the head of
the mast, it would seem that it is even less of an effect.
Am I missing something?

The weight aloft does make
a difference....I
don't remember
the numbers but 10 lbs aloft equals one man on the
rail.....or something like that !!
Now, bear in mind that I am a recovering racer and have
carbon main
and headsails.
Makes a difference and, after all, isn't your boat as
special to you as
any AC vessel.
