I am not up with this from a boat point of view, but I would have
thought that either angling the tail if the mill so that it
self-slowed as the breeze became stronger,

How would that work? Make the tail an aerofoil section so that as the
airflow across it increases it generates "lift" sideways and pulls the
mill round?

It's a lot simpler than that for a windmill pump. The tail is simply
spring loaded so when the wind get "so" strong, the spring is overcome and
the tail pulls the mill out of the wind into a stall condition sideways....

Don't know why marine mills can't figure this out. Probably has to do with
profit margins, like always....(sigh)
