Lee,

On average we are still able to make hull speed+ some dragging the three
blade prop.  We figured that for the .5kt loss we would suffer, the
advantages when motoring were numerous.  We can now stop her, pivot her, and
back her up, whereas before we were not able to do those with ease.

Regards,
Chris
