[C320-list] Folding props

[Steven Magennis]

Depends on the PHRF committee, but most likely, YES.

On Lake Michigan, the boat is rated as if it has a folding / feathering
prop, and you get a credit of 3 sec / mi for a two blade fixed prop,
and another 3 sec / mi ( a total of 6 sec / mi) for a 3 (or more) blade
fixed prop.  These credits aren't nearly enough to compensate for the
drag of these props under normal conditions.  If the wind is honking,
you could drag a big bucket behind the boat without affecting your
speed, but at less than hull speed, the 3 blade prop is a sea anchor
(especially down wind) while the drag from the 2 blade is much less
apparent.

It may have been coincidental, but the top three boats in the '02 C-30
Nationals had 2 blade Martec folding props, the next three boats had
two blade fixed props, and the last three boats had three blade fixed
props.  Even adjusting the elapsed time for the respective handicaps
didn't affect the standings in any of the races.
