I missed that comment earler, but think its a little harsh.
 - For a start, it is my obsevation that the great majority of the 
lock gates on the system are in good working order, a few leak a 
little, and a a few are in need of a little repair. But generally 
there in a very acceptable state.
 - Secondly, there is little damage to be done from gentaly pushing 
open a gate against a small head of water. The boat pushes smoothly 
and contiuasly against the middle of the gate, and the force exerted 
on the gate is nateraly limited to that of the boats thrust 
or 'static bollard force'.
 - And thirdly, as i have already said its not something we ever do 
as normal practice. On the odd occation that we do do it, im quite 
sure that is does far less damage than crashing into the gate a 
speed, which is something that seams to happen increasingly often.

I've not come on here to create enemys, ive come here because it was 
recomended by a freind as a good place to discuss our shared 
interests. Im sorry if any of my posts have caused upset already!
