My question is: is this normal?

I've never owned a Tanzer 22 but IIRC, it's not so much a swing keel
as a centerboard that swings up inside a stubby fixed keel. Wouldn't
be good to lose it overboard but wouldn't be the disaster that losing
a keel would present.
Anyhow, a swing keel on a Catalina 22 has a screw down clamp in the
cabin on the side of the trunk that keeps it from "bonkin" back and
forth. I'm not sure how you could accomplish that trick on a
centerboard that's tucked inside a keel. I'm interested to hear from
somebody that has one though.
