Re: Does it take much effort to turn a rudder on an inboard engine boat?
As 'Salty' said, one finger should do it (OK, so I spent some time on a 95' eastern rigged dragger that you sort of needed to lean on the wheel a bit to keep in a straight line). Anything less than 60' or so should be an easy one finger.
One advantage about the steering on an inboard is (if it is loose enough) it will tend to come back to straight on its own, kind of like a car, turn the wheel to take a corner & then when you let go it will seek straight ahead again on its own. (Though this is probably not so true with hydraulic steering or push/pull cable steering). An outboard or inboard/outboard (IO) will naturally want to continue on its own to a full hard over turn.
