Indeed. By 'same technique' I was including women on the boats, blokes on bikes on the bank, and boats stuck like glue. Yes, I tried to persuade a few odd people to try it last year, I think they just didn't get it. It was KK on Owl who showed me that trick. Coming out of double locks together is also useful for holding back at the end of the flight to get the lockwheelers back on. Mind you, we went one better last year, breasted the boats up with one person taking them through the locks leaving three on the bank (but with a dog and no bikes). Not Hatton but that would have been good.
