In my opinion the prindle setup is the best, once you modify it. Yes, the blades are a bitch when swept back, but there is alot of aluminim on the castings.

If you take the pull down, and pull up lines out of the rudder arm, and instead run them to a turning block over the tops of the transoms, you can rig a remote release and remote pull down that can be operated from both sides of the boat. And, best of all, you still have an emergency release should you hit sand.

So, if a blade kicks up, you can pull a line and lock it back down again. The prindle system works on a spring loaded notch that automatically locks in when the blade pulls down.

I had this setup on my p19, and it worked well in our area where we have a ton of weed. Without moving, I could release, dump weed, and pull back down again in 2 seconds.

I have tried this with other systems, and it does not work. Moving arm systems are very hard to remote because you have to pull the arms back and down. Forget it!!!

After breaking 3 ##$@@ blades on my tornado this summer, I am throwing the crap moving arm system away and installing a prindle rudder set. I want to be able to release and re-engage my rudders as needed, not when I can crawl across the boat and play with lifting the rudder arms, etc.

One last point. You almost always have to adjust the rake of the rudders when you transplant rudders. Be carful to make up some templates that show the exact rake of the existing rudders, before you take off the old set. When adding the new set, you will have to block out either the upper or lower gudeon, an align the to gudeons so that they are at exactly the same angle.
