After expending considerable effort to insure that my kick-up rudder would kick up if it hit an obstruction, I needed a way to securely hold it in the raised position during transport over uneven roads and bumpy launch ramps.
I removed the hooks off a rubber cargo strap and bolted the ends together with stainless hardware. A simple loop of line secures over a single stainless screw on the top of the rudder. As a plus the white line is easily seen under water and can be grabbed if one forgets to lower the rudder before departing the dock (Yeah, I did that once).
