I think 2005-05 was the change.
The change was made when we designed the EZ Loc rudder system. The system has to have the tiller crossbar aft of the mainsheet / sail clew. The action of raising the rudders require lifting the tiller crossbar high up.
If you simply set up the boat and rudder system... route the mainsheet in a direct line between clew and crossbar.
EZ Loc is one large plastic housing. Rudder up/down is simply up/down on the tillers. Older systems use aluminum castings and a black plastic locking cam. Unlocking requires a short lift of the tiller and a pull forward to raise the rudder.
