Let's not lose sight of the "issue" raised here. We're talking about speed limit enforcement. The data provided to a satnav service provider is not able to be intercepted by police and used for law enforcement of speeding offences.

Define "would allow"??? AFAIK no cars transmit their speed/location to anybody (unless they sense it has crashed).

The compromise on a narrowboat is that its narrow. Its a PITA, to put it mildly, inside at times. But its narrow because it is. There is no real issue with length. I've had a 68' narrowboat and the front bedroom went basically unused, such was the excess space in other rooms of the boat. If you want to live on the boat permanently, there will be many more compromises determined by the fact that its a boat, on a canal. Depending on your current domestic situation it might be equivalent or a huge downgrade, or a complete change that is a breath of fresh air.

I think you should monitor appropriate variables - I'd suggest current and battery capacity (state of health). The latter can be done with a diagnostic meter which a boat yard is likely to have. We normally refer to two different alternators on an engine as "domestic/leisure" and "engine/start" - I'd suggest using those terms, rather than its physical size. When you say one alternator was four times as warm - on what scale? Kelvin starting from absolute zero? Or centigrade? Or perhaps farenheit? Its a bit meaningless in itself, unless the small alternator genuinely was 1200K, or ~900 deg C. When you say you didn't turn any 12V items on, its basically meaningless if the fridge was running, since this is the main consumer unless you do something like run a hairdryer off an inverter.

AFAIK there's nobody doing an integrated, bolt-in kit of parts for this kind of thing. So its over to the small specialist converters who would take this on as a project, with all that entails. I suspect its one of those "if you need to ask how much, you can't afford it" types of question.

At 58', ours is just the right length for us. But its quite inefficient with interior space/storage. There are 2 wardrobes which don't really get used and only a few cupboards outside of the kitchen. We end up using the 'front' lounge as a dumping ground with bags etc there. So I'd lop 3ft off this and make it 55ft, maybe with some interior redesign too. Other than that, everything else is in sensible proportions so if anything I'd leave as-is.

How about "Priscilla the Prop"?

I can weld and have done car bodywork for friends in the past. Its alright having a fixed task such as "repair the hole in the wheelarch so it passes an MoT" but when the task is "adapt the boat to electric drive" it becomes "vague news" for the breakdown of sub-tasks in hand. Hull modifications? Brackets and bearers for new motor? Anything else? The easy part is the welding, the hard part is the discovery of what needs to go where, when. Much like, for example, doing an engine conversion in a car whose combination has never been done or documented.

Yes while the above is technically true, the laws are all there in black and white to see. There will be some fairly obvious areas and some grey areas open to interpretation. And we should give credit to eg trading standards officials who are basically neutral and professional in that they do this day in day out. What's more interesting is the law vs de facto what happens in the real world. For example, the law clearly states that speeding is an offence, but go on any free-flowing motorway and there's a significant number of car drivers who are exceeding it. The law is not 100% applied, nor would it make sense to devote the required resources to do so. Apart from a few posters, the words they type are largely theoretical, in fact many are no longer stakeholders in the canals.

MtB I think you're the one who has misunderstood or doesn't understand properly. Weight is a function of size, and size certainly can affect the canal (structures) for example if it scrapes the clay puddling away, or hits a bridge, or the edge(s). Its a bit odd expressing the size dimensions as weight but that's all.

We sell sheets too.

I had one shout "slow down" and I shouted back "I'm actually in neutral" then pointed out the throttle control which was indeed in neutral with idle revs.

I work for a furniture manufacturing company (beds and chairs). We never use the terms "king" size or "queen" size because people's understanding and expectation of what it means, varies so much. Also, we don't use metric units for beds. Ours are all made to order and we can accommodate 6'9" and 7'0" (and anything else if you really wanted it) lengths. But about 75% of the beds are 6'6" length and the others 6'3". The widths are typically 2'3", 2'6", 3', 3'6", 4', 4'6", 5' but we can join 2'3", 2'6, 3'0" etc as desired and obtain a headboard to match and fit.

Bridge 1 isn't narrow, but bridge 2 is. And the main line of the SU is a broad beam canal from Nantwich to (just before) Ellesmere Port.

Woah hang on..........for Cat D RCD/RCR requirements, the boat builder themselves can self-certify. So you can't say "the boat doesn't comply" if its been certified as complying!! Only a suitably qualified surveyor can negate the original compliance, or at least fail it on a PCA. If the issue is, you BELIEVE the boat doesn't meet the underlying standards, but it has RCD/RCR, then that's a different matter. An internet forum expert, no matter how experienced, isn't the builder and isn't a qualified surveyor.

Well.....no. There should never (in normal use) be any current from hull to negative terminal of the battery. The bonding is done to ensure eg a circuit breaker pops in a fault condition rather than raising the potential of the hull. If the hull is being used as a return path, it either indicates a faulty installation of something, or a stray connection by something else to the hull (which is also a fault).

But that would be a voltage drop between nominally grounded (negative) points which would always been seen, to a greater or lesser extent, in normal use. We're talking about the fault condition of a current flow between battery negative and hull, which should never occur.

The easy way to do it is go on Midland Chandlers website and pick one item from every category they list.
