As promised, here is how we open the paddles when going up a lock on our own, with ground and gate paddles, so the boat doesn't go from side to side when rising.. We have never had to rope the boat over on these types of locks and it works for us.
First open the ground paddle HALF WAY on the side that the boat is closest too.
Then open the gate paddle halfway on the opposite side to the boat and let the boat settle.
Then its back across the lock and wind the ground paddle up fully on the boat side.
Then across the lock again and open up fully the ground paddle which is opposite the boat side.
The boat should stay on the side that you opened the first ground paddle all the way till you open the gate to leave the lock..
If the boat leaves the lock slowly and you close the gate slowly the other gate should remain closed.
