That "VARA" rudder is just damage waiting to happen, so be careful. When I owned that boat, I abused the rudder and cassette by grounding, forgetting to raise the rudder when trailering, dropping the rudder insert, etc. and it is expensive. Get in the habit of removing and storing the rudder at the ramp, and having the swing-keel down when in thinner water. If you hit the bottom of the rudder, it will lift the top of the cassette from the cassette barrel. The bungee you noted was not useful for keeping the rudder up.
