Articulating rudders are a little more complex than a trim tab. The articulating end pivots at a incrementing angle as the rudder turns away from center. There are no hydraulics or additional controls like with trim tabs. It's all mechanical with struts and pivots that has to continue working in harsh underwater conditions.

And that $8,000 was a few years ago. I'm sure it would be higher in 2019.
