At the last lock we did the same, crossing to the other side to the free lock, but Shane’s early signalling made that easy enough to negotiate. A boat appeared as I was leaving and it looked like it would be easier to pass on the “wrong” side, which is common at a lock and I indicated this, but unbeknownst to us there was a strong stream of pumped water coming out just where his bow was so in stead of staying on course he was thrown sideways towards me just as I was trying to go round him. I was also being pushed over by the rush so there was no collision but I was more in the trees than I’d have liked, but we got back into the main channel unscathed.
