Thanks everyone for your responses. We will moor up above the Dimmingsdale locks as recommended, and I am heartened by those who report pleasant cruising along this stretch of the system.
I also appreciate the views of people on the subject of banditry. I admit I tend to worry about this subject more than your average Joe, and I regret that it sometimes does rule my decisions. However, we did not let it stop us choosing the lifestyle we wanted on the canals, and that decision was made with full awareness of all the media reports on trouble.
I will take heart from those of you reporting many years without trouble, but I will at the same time continue to exercise caution when I moor up to reduce the chances of any 0.01% incidents happening to me or mine.
I too am looking forward to decades of boating without incident, and despite being on the water for only a week, we have already met many friendly joggers, fishermen and boaters. May this be a sign of times to come
Thanks again
Spencer
