[Rhodes22-list] Rudder angle, tacking, and racing

[Peter Thorn]

Lee,

Sailing without the "rudder brake" is sometimes practiced by racing sailing
sailors to improve boat handling skills.  By adjusting your weight and the
trim of the sails you can make the boat head up, fall off or steer a
straight course.  More heel to head up, more hike to fall off.  It isn't as
easy or intuitive as rudder steering, but it can really sharpen your boat
handling skills.  With furling sails you should be able to get the boat
balanced well, although I haven't tried this in R22 yet.  Please let us know
what you learn.

PT

You guys got me thinking.  Sometimes when my sails are balanced and the wind
is steady and there isn't much chop and the moon is in the 7th hour, I sail
hands-free without the tiller being locked into place.  This is typically on
a close reach with the centerboard up, and any slight shift in rail meat can
mess it up.  In those situations, do you think I could pull my rudder
completely out of the water?  If a little marine growth can slow you down, I
can imagine how much drag a big rudder causes.

My boat is still in the water--I'll give it a try next time out.
