...the rudder blade must be submerged into the rudder head the same depth whether the rudder is up or down or halfway up or down. This places the rudder pivot bolt approximately in the center of the rudder head pivot chamber...
Bill,
If it is not asking too much, I would like to know what you think of the pivoting dagger rudder concept. (attached)
It has the same blade area inside the head all the time, but since the pivot is not in the center, the stresses are quite different.
Thanks!
