According to the operator he was attempting to dock the "double eagle" at the anchorage marina located on silver lake.  Operator said that as he began to dock, there was confusion as to his slip assignment.  He advised that maneuverability became difficult with the large vessel and that he struck the stern, back, of the "dream on" which was tied to the anchorage inn marina's dock.  The collision caused two of the dock lines to break.  Operator felt that the stabilizers on the vessel did not function properly, thus causing him difficulty maneuvering.  After the collision, the staff of the anchorage marina discovered two broken pilings to their dock as well.  The uscg responded to the incident and no charges were filed.
