How does one coat anything with Teflon?   I don't know anything
about it.   Ignoring the speed thing, Teflon would certainly limit the 
problem of plant growth on the hull.

As far as speed goes ... I have a report here that what works best
is to put longitudinal grooves in the hull.   The improvement is so
small that it takes a lot of power to make the machining worth the
trouble and the cost.
