That's fine, you do that, it's your choice, none of this new-fangled rudder rubbish for @bizzard, hurrah!!! 🙂
(though IIRC the patent's about 60 years old, so it's not exactly "new"-anything...)
But please don't assume the Schilling *doesn't* work with no power, it's just a bit less effective than a big flat plate because it's shorter -- I've used it with no power and it steers OK, but you need a bit more rudder angle than a big flat plate. On the other hand it carries on working over to much bigger angles than a flat plate, so I expect it can move the boat just as well, but with a bigger difference in the required rudder movement between power on and off -- so the feel takes a bit of getting used to, like having a rudder that carries on working well past "normal" angles does.
