[C320-list] FW: Re: Neutral or Reverse

[Kirk McCullough]

I have read in a number of publications over the past 10 or 15 years that a 
stationary prop creates less drag that one that is rotating ( freewheeling). 
I have never noticed any difference however, when trying "in gear" vs "out 
of gear" sailing.
