Greg, Last week I moved Helene to a swing mooring off Wrabness, about half way between Manningtree and Harwich. There is plenty of water and it moves quite fast. Over a couple of days it became very clear that when the rudder is left fully down it is much less active — quiet even — compared to when the blade is lifted. So my question to you — Do you raise your rudder when the boat is left on the mooring?
