subject: [Paddlewise] modification to reduce weather cocking
Date: Sat, 31 Aug 2002 12:11:59 -0700
I was out in a wind that blew from my starboard aft quarter a few days ago,
and had to paddle several miles at that attitude.  It required constant
correction to overcome a persistant weather cocking tendency, and I grew weary
of the extra labor.  I'm thinking of reducing the sharpness of the keel line
in the front quarter of the boat where it is quite pronounced, in order to
create a more neutral balance between the bow and stern.  This would be a
similar effect to lowering a skeg in the stern, except that it is actually
raising a bow skeg, so to speak.  Before I undertake this correction, which
involves structural work to the boat, I'd like to hear any arguments against
the idea, especially regarding the possibility of some other adverse steering
problem I might create.  Let's presume for the sake of the discussion, that
I'm going to do sound structural work, and that I'm not going to remove so
much material as to overcorrect.

I think one would have to be a genius or extremely lucky to decide on hull
shape modifications based on theory or intuition, rather than on
experimentation.  (Unless you are an experience designer who has already
learned by his mistakes.) Furthermore one should not buy a boat in the first
place without testing it in aft quartering winds.  This also applies to
boats with a rudder.  With or without a rudder all boats should be easily
manageable in these conditions.

In theory such an approach is fine, but any hull modifications
are a pretty permanent experiment.  The time required might be
better spent on either installing a rudder, skeg, or some sort of
temporary/removeable skeg.  My boat also weathercocks and I've
also been dreaming about possible fixes, but have dealt with it
so far by running more of a zig-zag course when needed.

Play Hard,

much easier than re-building your hull is buying a new boat that handles
better.

What you want to do will help, but hitting on the head, the amount to remove
will be a serious challenge.  Not to mention the mess and work involved.
Take off too much and you're going to have a leecock issue.
