Given what's in the loo tank I don't think you need to add anything....

There's a small nest of them on the T&M north of Middlewich

Not 6 years at all - C&RT were unable to give us data for over a year. We only mark a record as updated if something has changed and for a couple of years all cart could give us was new additions - not changes to existing records I have the latest data from C&RT and that shows 507322 HOME AT LAST EVANS & SON

I hate to think what this has done to their hull. https://www.bbc.co.uk/news/av/world-asia-49470836/pacific-pumice-raft-left-no-water-visible

What I actually said was: We got an agreement from them that we could cache their data for a limited time rather than having to call their API for each and every page load. We refresh all the canalplan caches in the background and set it up accordingly. We added W3W because we had several people asking us if we could add it for various reasons. We then talked to W3W directly about their API and call rates and caching and came to the agreement we currently have with them. If things change with them then we will simply pull the plugin and purge the data but leave the rest of the Geo location data in there. When Google started charging us for map usage we dropped Googlemaps and implemented open maps. When Google got unreasonable with their demands for their SSO we dropped that from our list of SSO providers. If things change with W3W or Facebook or any other external service we use which means it no longer works for us then we will drop them.

Of course if they'd made IPV6 geolocation specific then you would have had several of them per square metre.

W3W seems to create english word set for locations in Paris - not sure what it would present to a frenchman.

We just put all of them in on Canalplan - so as long as you allow Canalplan access to your location and your browser gives good values to Canalplan, your options are almost endless! However getting an agreement from W3W was a bit messy as we cache "static" data and they don't like people doing that... which seems odd as surely a place can't change its W3W code....

I tried to get clarification from C&RT about what part of the whole thing was Black Sabbath bridge - was it just the bridge for Broadstreet or the whole thing. But they didn't really seem to know so we decided that it meant just the north bridge which supports the footpath and seating area

There you go again. They don't provide me with diesel - but I can go to a boat yard and keep my 250 litre tank filled up - if I don't then fill up for 2 weeks as I do a couple of hundred miles then that's my choice. There is, at the moment, no equivalent of the same situation for electric canal boats. As no-one can even work out how to keep a nation of EV's fuelled up without investing billions in infrastructure the chances of anyone working out how to keep a few thousand canal boats on the move are just about zero.

We keep drifting away from boats and back onto EVs. Given the problems with EV charging schemes (my work place for example couldn't put in more than a couple of charging points as we're already overflowing the car park) how likely is is that even if someone comes up with a workable, reasonable cost, electric system for boats, that lets people do 8 hours a day, each day, that there will ever be a charging infrastructure to support these boats, and to handle the peak load in the summer months at popular overnight stopping points such as Nantwich and Middlewich. until someone gets sued for it. Given that people sue councils for tripping over uneven paving stones it wont be long before someone sues for tripping over a power cable lying across a public walkway. There are even tales of cyclists suing boaters over mooring pins on towpaths.

trailing mains power leads over a public pathway.... like that's not going to lead to problems.

But those are ICE - once we've got "all new boats must be electric" then we'll move onto all existing boats must be electric or be scrapped unless they are historic. So then there won't be marinas full of boats that don't move but possibly pay licence money to CRT. The cost of installing charge points over the system is, at the moment, totally prohibitive - imagine upgrading all towpath so it can carry MW rated cabling.

3 hours a day will kill the hireboat companies - people are not going to want to take weeks to do the Llangollen. It's not a race or some sort of a challenge for us either, but for a lot of people not moving because it's been cloudy for a day or so, or only doing 2-3 hours isn't what they want from canal boating. So the cascade is pretty catastrophic - boat yards close down, marinas close down, C&RT lose even more income and maintenance stops, and your 3 hours a day wont be possible because there wont be a canal network.

so 2K plus another few K for batteries and panels and controllers? I still suspect that a normal narrowboat will not have the surface area needed to give the daily range many people do in them.
