[C320-list] Question for Designer Douglas

[Steve Magennis]

Whatever wind will get you up to hull speed down wind with your three
bladed sea anchor is the crossover point.  At all wind speeds less than
that, a boat with folding / feathering prop will sail faster than a
boat with a three bladed fixed prop (assuming all else is equal).  If
you only sail upwind, the crossover windspeed will be slightly slower.
