Finally got my new rudder installed and posting pics. I cut this blade from a piece of 1.5" x 2' x 4' UHMWPE plastic using ordinary shop tools....belt sander, angle grinder, planer, etc. I'd like to think it conforms to the NACA 0012 airfoil specs, but there might be some slight variations Smile







and pic showing the bottom bearing and stop collar



The nicest part of this rudder is how it retracts. No more ropes getting tangled or hung! Basically turned the whole thing into a Jackscrew. Some pics and a video:

Using a 5/8" ACME threaded rod with some linkage to the blade, the blade can be retracted and extended from the cockpit by rotating the nut at the top of the shaft.




Here's a link to Rudder Upgrade Part 1 that shows the finished bearing assy inside the cockpit

Very cool!!!

I've only had my Chrysler for a little over a year, but one thing that I've noticed is how the rudder control line can slip through the clam cleat under sail. As the rudder is pushed upward by the force of the water, the weather helm increases. It seems as though this would prevent that. Thanks for sharing!
