I have heard all sorts of horror stories about spade rudders, in general however, my experience has been very good, so far. I did notice that the rudder
tube, where it bonds to the hull
, was suspect so, I added a 1 inch plywood
strut, on edge, straddling the hull
, athwartships, to support the tube and move the stresses outboard
, the strut ends rest on pads bonded to the hull.
I also try to trim the sails
properly and minimize the loads on the rudder
, as a matter of course. So far, so good.
