Hi Mike,
 
I understand the part below about the compressive stress on the boat due to lack of shrouds, but the other two (torsional and point load stress) kind of escape me with regards to a freestanding mast.
 
Is not the mast point loaded at the mast partner location (the deck in most cases) once dropped into place and placed under wind load by the sail(s)?
 
Is not the moment generated through the mast focused into the hull torsionally through the partner location as fulcrum and then, subsequently, to the mast step?

The nice thing about a freestanding mast is that there won't be all sorts of torsional stresses on the boat, nor point loads and compressive stresses on the mast.
