A foundry that cast thousands of parts for some of the world's most popular sailboats has closed its doors. With their demise went the very abused tooling that was once used to cast Catalina's rudder locking disk sets. We know you can't sail without them, so we started over, working with modern technology to re-create a part that is superior to the original.

As you can see, the disk on the left has a hexagonal recess that holds the hex head of the rudder lock bolt captive. Since the disk, when installed, can't rotate, you can tighten the rudder lock handle with only one hand.

Caution: #Z3052 Anti corrosion gel must be applied to the threads and the through bolt where it passes through the rudder cheeks to prevent seizing and corrosion. Failure to do so may make it impossible to remove the bolt from the rudder cheeks in the future. See related part below.

If you have a problem keeping the kick up rudder blade down, try adding the kick-up rudder detent rivet listed below.
