[MHml] flying helm (was winch vs tackle)

[Bill Gibbs]

 Simon,
I did not say a leeward "force".  I was describing the components of our
helm "balance".
Probably the more correct way to say it is that more dagger board moves our
CLR aft, changing our helm balance in the more lee direction.

Here's my guess for Peter (making up the facts to suit).  More changes were
going on than just the hull coming up.  He was sailing his cruiser high with
a reacher/screacher, almost luffing the headsail.  The gust/puff clocked the
apparent wind aft significantly, and now the big headsail is not near
luffing, but hooked up and powered, increasing the lee helm.  Furthermore
Peter is easing the main sail at the same time, further changing the helm
balance to lee.  Net effect is a big shift to lee helm as the hull rises.

Excuse me ?????

Everybody else's daggerboards produce a WINDWARD force!
