I experienced a soft grounding over the weeked and required a "tow" to get me out of the muck. In the process of being towed the rudder of my (Cal 24), must have hit hard ground and appears to be jammed!!! I am able to pull the tiller to starboard, but it only goes to center before stoping (to port). The marina will check it out during the week. Any suggestions before I have them do the work???
