It looks like the revised rudder brackets work OK. We had a variable 5-20 knts on Sunday & the blades didn't budge once locked down. Haven't had the acid test of running out of water but don't expect any problems. Have attached a photo for interest. If you want more detail let me know by private message & I will email the 8 photos I have and a short description of the design. Please note, no warranty is implied for anyone using this method, it works for me, but may not for someone else.
