Thrust vectoring

it is caused by asymetrical thrust of an angled prop shaft. When backing up the
blade coming up to the hull has a much greater "angle of attack" than the blade
going down from the hull. Thus more thrust on one side than the other.
(there is also asym thrust when going forward, but the rudder can compensate
for this as long as the prop is *pushing* water over the rudder, or the boat is
moving forward)
===========================
OK, the implication of your assertion is that a prop shaft parallel to
the water line, and with little or no hull/aperature entrapment, will
exhibit little or no prop walk. Many full keel lobster boat and
trawler types come close to meeting that criteria.
Does anyone know if that holds up to real world experience?
