If you are really keen and are building your own battery, I came across this free paper, "Temperature effect and thermal impact in lithium-ion batteries: A review," Shuai Ma, et al. Progress in Natural Science: Materials International, Vol. 28. Issue 6. Dec 2018. Pages 653-666. https://www.sciencedirect.com/science/article/pii/S1002007118307536 It explains how the Lithium Cell works, and how it is effected by high and low temperatures, and the importance of monitoring it. A PDF download is available.

There are Chinese compressors available, which has brought prices down, rather like Chinese heaters. Newer brands, at a lower price, may not be trusted. Some are converted domestic 240 volt fridges, so there is the purchase cost plus the conversion cost.

Air conditioning is more common on motorboats, units are available from Fischer panda, and Dometic. https://www.fischerpanda.co.uk/self-contained_units.html https://www.seacraftmarine.co.uk/air-conditioning-refrigeration There will be fitters around, Fischer and Dometic will be able to recommend a supplier and fitter nearest to you. The units can be physically large, and you would have to work out where to put it. Installation would involve some disruption, and they use your electricity up. Some can act as heaters in the winter.

...plastic covers in 13A sockets... It is about stopping small children poking things into the holes, like they get Lego bits stuck in their ears.

The cost of a bedsit, in Wandsworth, is £2,000 per month, a recent figure. So I have no reason to believe an increase in licence fees will drive many off. Those who can't pay, and won't pay, will game the system for all it's worth, and the cost of enforcement will escalate, The trust could, if they wished, and at a lot lower cost, remove stuff left on the tow-path, and make a point of clearing them on a monthly basis. The thinking behind this is that they like to live with their own mess, for them, it would be a great inconvenience not to have the wrongly appropriated outdoor space beside their boats. In addition, the trust would get to know who wasn't moving, and who the worst offenders are.

Winning boats at Crick, had windows, and bug screens, for their hatches.

Winning boats at Crick had them, and mosquito nets to pull over. Pure indulgence.

Thank you, some things I avoid because I don't know how they work. I am a bit of a technophobe. My daughter says I don't use half of what is on my phone. The tablet could be a good way to go. As Momac says above, I believe the problem with 12 volt projectors has been getting the power for a large bright image in a room, but might be OK with the small distance across a narrow boat.

Sorry for my ignorance, but does that require a subscription of some kind, and does it connect via your usual internet provider? Also, do you get a million adverts, and Amazon offers. Thank you.

The UV treatment is an add-on, not included unless asked for. I remember seeing the filtration standards for the General Ecology Seagull filter as used in yachts, more years ago than I care to remember, at the Earls Court Boat Show. The filtration is very effective for organic chemical and crop residue, Bacteria, fungi cysts and virus, it did not remove heavy metals that well, or dissolved salts. It is a filtration system, not an RO system. Likewise, it improves the taste of the water, for about £600. Principally intended for yachtsmen picking up water from places around the world where the water quality cannot be assured, and has been used by many cruising yachts. Though nowadays, many will use an RO unit, as it can also be used for desalination. There are many RO systems available which could be used on a boat, and it might be well to look around to see what is out there. As has been said, ideal for permeant moorers, who would lose their pitch if they ventured out to fill their tank.

Maybe for commercial reasons, and not being, strong, and "traditional," rather than any inherent disadvantage of the material?

Glass reinforced plastic, has proved to be a very suitable, long-lasting, low maintenance, corrosion free material, which allows for serial production, without needing expensive, highly skilled labour. Despite opposition from some traditionalists, it has been use in the past, and would appear to be a better material for narrow boats. While those who regard canal boating as a contact sport might disagree.

Would that be an oar?

On their website there is a diagram showing the filtration stages of their reverse osmosis system, including an optional UV filter. I have little doubt that the water is safe to drink, delivered direct to the kitchen tap. I have doubts about storing a tank of water with no antimicrobial treatment, such as chlorine, to suppressed growth in the tank. Over time the tank could become quite contaminated. In addition, we do need some trace elements, such as magnesium, in in our drinking water, both for taste, and for our health.

The Water Freedom unit needs a fresh water source, currently it is not suitable for salty water, but that is in development. A DIY version for use on a lumpy, salt water boat is discussed here: https://www.pbo.co.uk/expert-advice/diy-watermaker-for-your-own-fresh-water-supply-75039

https://commonslibrary.parliament.uk/sewerage-connections-for-new-housing-developments-in-england/ The sewage system has to be built to adoption standards to be adopted by the Water Company. If not, the Highway Authority won't want to adopt the road above it. This happened to me on an estate in Devon. I sold up, while they were still arguing. The Building Control officer seems to have been half blind, as the developer managed to lay the whole estate with porous pipes and backfill without him ever seeing. The Council had already given him his deposit back. lol

Unfortunately, the law requires the Water Companies to connect up any new housing, but puts no duty on the planners or developer to make provision for the effluent disposal. This waste system then gets overloaded.

Copper rooves turn green with rainwater, which doesn't usually contain salt. I guess it will turn green in time.

From their website: Can be used in generator mode to charge batteries. Please request further details. You will need to ask.

My Whale pump came with a set of adapters for different pipes. Your supplier may be able to supply the correct adapters for you, you cannot be the first person with this problem.

There is plenty of helpful advice on DIY boat canvas work on this site, though not canal boat specific. https://www.sailrite.com/learn/diy-projects/marine-projects?facet_howto_series=Traditional Dodger Series Unfortunately American, but you don't have to buy from them.

Microplastic pollution is found everywhere, from deep in jungles, Antarctica, deserts, and the deep ocean, and permeates the food chain. They are found thought your body, even in your brain. No matter what they say about potability, plastic linings or coatings, bottles and food containers, will shed micro or nanoparticles and compounds, which you will ingest and increase the amount of plastic inside you. Each to their own, drink from it if you like, take part in the great unregulated human body pollution experiment. Stainless steel tanks seem much safer, sustainable and recyclable.

I think CART know when you are working the system. In London, a friend reported having a Coot's nest on board to the mooring manager, who agreed an overstay. CART still threatened them with a six month licence if they didn't move. I believe the dancing troop came to their assistance.

Hawk House have been around for some time and are a respected supplier. "Hawke House was established in 1991 as a family firm committed to supplying sailing and motor boat enthusiasts worldwide with first class interior linings, upholstery, canvas, fabric sundries plus marine plywood to both retail and trade customers."

If I change an engine, for an essentially like for like replacement, allowing for a newer model or of a different manufacturer, then I think I can make an informed decision that no PCA would be needed, as there has been no material change to the boat.
