Default Is it a sailboat or a motorboat?

Someone invents a windmill powered "sailboat". This windmill generates
electricity that, in turn, charges batteries which are used to drive an
electric motor that turns a propeller in the water. The windmill can be
swiveled an any direction to face the wind.

What is it? I'd say it was a motorboat when underway using the electric
motor and the water propeller. But, if the windmill was turning charging up
the batteries and the boat's electric motor was turned off and it is
underway on a broad reach powered by the wind on the air propeller then it's
a sailboat.


Correct.

Machinery is in use but not "propelling" machinery. Or since the windmill is
a machine can it be said that it is propelling machinery?


Windmill is a sail.

If so, is not a
sail that winds up on the forestay or inside the mainmast also "machinery"
especially if it's wound up using electric motors which is often the case on
larger yachts. So should those yachts with roller furling be labeled
motorboats by virtue of the fact that propelling "machinery" is being used
to propel the vessel?


Machinery is only used to set the sail much as a normal winch is a
machine used to set the sail
