I have agree. Is it not possible that the failure was at the lower rudder bearing, and the increased mobility of the stock caused stresses up at the quadrant. Still seems odd that there is not much sign of water ingress in the video, perhaps disproving my theory.Seems odd to break the stock a long way above the lower bearing, which is the most stressed area.
That suggests the quadrant must somehow have damaged the stock?
I don't think the buoyancy of the rudder will make much difference, the leverage of the blade against the single lower bearing would probably jam the stock in the bearing with even the slightest motion of the boat. Getting a simple dinghy rudder on its pintles afloat can be difficult enough.
