One or both?
HAVING A DISCUSSION about the practice of opening the bottom gates on broad locks, the subject of opening one or both came up.
We were taught that it was good practice to open both gates, mainly because the edge of the unopened gate is likely to get worn from boats hitting it. Although many would say they’re good boaters and can fit through the gap, that does not resolve the fact that many gates have damage to them.... about rubbing strip height... big enough to put your hand through when closed and empty. Now, I can accept many people can go through without damaging the closed gate and it used to be standard practice years ago, but times have changed and nobody is perfect... that slight change in wind or current could trip up the best helmsman. But surely, the biggest case for opening both is that, if you don’t, other less confident boaters will be more likely to try to negotiate one open gate and cause damage.
With the amount of lost water these gates waste and the cost of repair, surely the Canal & River Trust should be promoting opening both gates as the correct and preferred way?
