Some random questions -- pretty basic stuff

It slows you down considerably -- by a knot or more if you are running 2-3 knots. And that tempts you to rev it up a bit, which is when they find you (they go after RPMs, not speed).

10 degree rudder is the most I use unless I simply must present a better profile.

Full rudder doesn't affect your signature; that's all angle and depth.
