I didn''t think there were three other Mirage 236s out there. I have hull 68, plus an original sale flyer by the builder, Mirage Manufacturing of Gainesville, FL. The company still exists, but is strctly power. The flyer shows a transom mounted rudder, but#68 was, at one time, equipped with a spade rudder hung through the transom. It was missing when I got the boat, so I built one and hung it on the transom. Works fine. Due to leaking around the port chainplate, the bulkhead was rotted so I replaced that.
I don''t have the Mirage web address, but you can get it by doing a Yahoo search for Mirage Manufacturing
