How to build a Sailboat Rudder for my Catalina 25

The rudder broke off my Catalina 25 and did not feel like spending over a thousand dollars on a new one.
I've had some ponderosa pine laying around in my garage, however I should have used marine grade plywood. I would have been easer and quicker to craft.

How’s this thing holding up???

I had it for about a year...no problems. The sailboat was sold. The guy who bought it had her for two years. Did not complain about it...
