My boat has short bilge keels and will happily spin around until it
drills a hole in the water.

I can feel the coupling I mentioned earlier, and if you have a boat
which turns easily, you might too, if you are not er, "insensitive."

My HR28 had a relatively short keel, and it too reacted in the same
way.

I built a wheel steering system from sewer pipe etc for it, and had
about 45 degrees deflection, as I do comfortably with the tiller on the
Tyler 29, and hardly ever need or needed to use full deflection.

The rudder is actually a brake. We steer the boat by adjusting the
sail balance and trim.

Both had counterbalanced rudders, and neither would hold a course
unless very carefully set up in steady conditions and only with the
tiller or wheel lashed. If either started to turn and was let go, it
would just about screw itself right down into a whirlpool.

Management of angular momentum is something to learn, like feeling the
groove, but is more delicate.
