I have been arguing for years (since the Lowland Canals reopened) for boater operation of locks, bridges etc but with very little success. The hire boat operators up here seem to have a much stronger voice and they don't want hirers to be given the chance of sinking a boat (the locks have gate but no side paddles). Also, when BW Scotland put in any moorings they seemed to be under the impression that they had to be pontoons with water and electricity available. It has taken years to convince them that most boaters would like the opportunity to moor wild if they could determine where the towpath stopped and the canal started - the BWS ecologist didn't want the towpath edge cut as it was needed for wild life!! The fact that the wild life have all the offside bank and that boaters couldn't get to the edge and off their boats in an emergency didn't seem valid arguments.
Then Scottish Canals (the new BW Scotland) decided that boats might be nice so they put lots of money into creating residential moorings, all complete with a nicely painted hut to keep belongings in.
In the last year, we are seeing evidence of more basic visitor moorings being provided so I live in hope that SC see value in having moving boats on their canals.
Re the weed cutters. We need them all!!! Because there are so few moving boats, the weeds get a chance to grow, both from the bottom of the canal and the towpath edge and in the summer, all the cutters are in use almost every day.
Re the sea lock at Grangemouth. When the Millennium Link bid was prepared, I think it included an extension to the canal and a link to the River Carron similar to what has just been created (with the Kelpies) but that bid failed on the grounds of cost and a lot of things had to be dropped before the bid was accepted. The present sea lock was a compromise and although there is not a big window of opportunity to use it, I don't think it is as short as 20 minutes a tide although a lot depends on the dimensions of the boat as the height of Kerse Road Bridge is also a limiting factor to some boats.
I live in hope that one day the Lowland canals will give us the freedom to use the canals that we enjoy south of the border.
