Many years and many designs flowed under the bridge....
This one could be it! or almost it....
Keep Shunting guys,

The rudder mount looks light, brother, but your work is remarkable. I understand the shear pin, but it looks all a but weak to the sea to me. Tell me I'm wrong. I would make the longitudinal supports a bit stronger; like with a brace.

This was your best video by like 1000 times because you were brutally honest with the rock eating business. Loved it so much.

If you make it to America, I'm buyin.

 

I like the articulation, stowability, and kick-up features of the rudder.

If I understand correctly, the U hoop will we welded to the latch plate to act as a stop/guide for the shaft which pivots in both Axis at the top fixture?

I assume you will then use a “fuse” of some sort to pin the latch plate and dial that in for appropriate kick-up forces so it can kick without transferring the impact energy into the lower bracket bolted to the hull?

Your absolutely right about the challenge of accomplishing articulation like that.

It looks easy until you start to ask a system to function in different “modes”.

And on top of that, how to keep it light, simple and streamlined so it doesn’t detract from the overall design.

 

Looks strong to bro, 3 mm copper wire shears at 80 kg. I built a jig that was as long as the rudder, and we were cutting stuff all day long, it came down to 3 mm copper wire or 4 mm aluminium rivet, I chose copper. I cant imagine the water pushing the rudder aft at that force.....

Happy you liked d vid, Keep Shunting.....

Yes and Yes, you understood what's going on later on I will upload a vid of the finished system. I built it with regular steel and then started all over with SS.
I tested breaking loads different materials and at different sizes, I chose 3 mm copper wire, 80 kg of force at the bottom of the rudder, will cut the wire and release the blade.

Over a decade of proa building and messing with rudders and steering systems.... It's been a long road, 4 years ago I started thinking about this rudder, I gave up on it many times, then went back to it.... I feel good about it, and I think it will work.

Happy U like it
