Hi everyone, thank you for taking the time to read this.
I have a fairly stupid question, and I know this topic has been talked about quite a bit, but they are all fairly old. I have a 70ft ex black prince narrowboat, if I take the 2ft stern fender off and possibly the front one, we can get the boat down to under 68ft. I know it has been said that max narrowboat that has got though was 64ft, but I've measured the locks on Google maps, the locks are 70ft long and take away 2ft for the cill and the gates to open, you might just get a 68ft through, it's highly doubtful. But when the time comes and I'm in the area, I will give it a go none the less.
