Then if you intend to come thu Nottingham and onto the Trent choose your boat with care - a couple of the bridges around Meadow lane are quite low - and, if you do have a wide beam the beam can restrict the height of bridges you can use. Hopfully the picture makes sense. On an arched bridge, a NB with a higher airdraft can use a bridge that a WB with a lower airdraft cannot

This one ? Apologies if this is your picture. I simply asked google pictures for a 'cutaway boat calorifier' and it gave me this. There was no indication of source I have today tried to follow it back to its source and it ended up at a 'dead' link in 2012

Yes - there is typically a question like "are there any other pertinent facts that may affect our quotation or offer of cover ?"

A calorifier can be designed to be installed horizontally or vertically - make sure you get the right 'type' Here is my Horizontal one (yellow foam jacket. and my Vertical one (blue jacket)

The calorifier is an assembly of parts - it is primarily a large copper cylinder (some are stainless steel) and most are covered in a heat retaining jacket, There is a variety of pipes inside that act as heat exchangers for hot water coming from the engine, and another set for hot water coming from a gas fired, or diesel fired boiler, there is often a heating element (electrically operated immersion heater) installed inside the 'tank'. The whole thing is known as the calorifier (but the jacket may not always be included).

Are you planning on having a mooring somewhere on the Trent, or CCing ? Outside of 'permanent moorings' the 'visitors moorings are limited to 48 hours. Having spent many years on the Trent, it is not advisable to rely on being able to moor in the /winter - the water can rise very fast, and if you are 'tied up to a tree overnight' you can lose the boat. The river is 'huge' and the currents can get very strong and it has been known for 'canal boats' to not have sufficient power to stem the current. There have been several instances of boats being swept over the weirs Aboat was bought into our marina in Newark in a state of 'dissaray'. Inexperienced boaters came out onto the Trent from Nottingham, they were not aware of the currents and ended up sideways against the big oranage "dolphins', as the boat started to roll over the skipper wife fell overboard - he grabbed her hand and then had a dilemma - did he let go of her and let her go over the weir, or keep the engine going and try to steer but risk chopping her up in the Propellor. He let go of her. The boat rolled under the dolphins, he was swept off the boat. Long story short - both of the survived and C&RT came ad towed the boat into our Marina. The owner came to the marina to get some personal stuff off the boat and all we got from them was "it wasn't our fault - surely someone has responsibilty to warn or stop boaters going on the river" Another boat on the weir : Rescued off a widebeam. These are not everyday events but the 3 quoted above were within a 5 year period whilst we were moored in Newark If you are planning to use the Trent - GET A MOORING in a Marina so you have a safe haven in the Winter (or Summer) floods. If you want to read up a bit more ............. https://www.airbornesappers.org.uk/cromwelllock.html 10 soldiers died as they went over the weir.

But, if you read the BSS, you will see that the existing 220/230 volt AC electrical system is not covered by the BSS as it not a 'REQUIRED' check, yes, there advisories telling you how you could improve the system but you cannot fail the BSS 'on mains electric' checks, unless you are a commercial or hire boat. You could have a shoreline with male 'plugs' on both ends, you could have multiple 220v sources all connected up to a single unit, and you'll still pass the BSS. So, what would you gain with your portable power station ? Examples :

To be exempt from the RCD/RCR as a replica it must be : "....original historical watercraft and individual replicas thereof designed before 1950 built predominantly with the original materials and labelled as such by the manufacturer" As the hull is a very large part of the boat, that would suggest that "replicas" of Iron boats built using steel would not be exempt from the RCD/RCR or, be classified as replicas.

I'm sure it is a good read, but would warn against relying on facts from that time. The problem is, like with many books, that were written 'years ago' (2013) the EU and the World has changed a great deal since then The RCD was revised in 2017 Brexit in 2020 We were in the EU in 2013 so we, and our boats, were in the 'single market' we could come and go as we pleased. Now we are a "3rd country" the same as the US or Africa or Australia and we have to abide by the same rules as they do. Things that were easily done then may be impossible now. Everything making it more difficult for UK citizens to take their boats over the channel, and, live in Europe.

Removing an ICE engine and replacing with an electric motor and stacks of batteries (either LA or LI) is an MCC. Exchanging domestic LA batteries for domestic LI batteries is less defined. On the face of it, it shouldn't be an MCC, but, if safety is impacted, you can see the argument that it should be installed 'properly' and be subject to an MCC and/or a PCA to ensure the installation has been done in accordance with the ISO / Manufacturers requirements. Fitting LI into a boat during manufacture means the whole boat should be built to the relevant ISO specifications (or demonstrable equivalents and evidence provided) so should not be an issue. DIY fit-outs on a shell already require RCR compliance / PCA, (despite the lack of acceptance of this point by some) so should be ''safe' and in accordance with the requirements. The question becomes (as high lighted by IanD) should UK inland waterway boats, fitting LFP batteries, be subject to the same requirements as lumpy water boats, and if not, what requirements should they be required to meet and who checks and enforces it ?

The 12v outlet on the Jennifer will (probably) be around 6-10 amps. You can plug a 50 amp mains - 12v battery charger into the mains outlet and get a lot more amps for your £ of petrol.

As the RCD decision was published in 2022, it would hardly be likely to quote a 2025 ISO. The ISO 2025 issue you pasted says the same as the 2022 RCD decision, ie follow ISO 9094 and the manufacturers installation instructions

It looks pretty much as if the ISO 23625 2025 is simply following on from the 2021 version and ISO 9094, as quoted by the RCD in a question regarding Lithium batteries in 2022 Ie : Install following the manufacturers instructions

I was suggesting that if boating authorities got their act together and had 'united disussions' something less resrictive may result. as the ISO decisions are agreed by organisations representing 'millions of boaters' Power in Numbers !! I'm more surprised you didn't pick up on - Who has issued approval for LFP on yachts, or vice versa, who has refused approval for other types ?

I believe that only exists in the UK you may need to check that out. It should still have a VAT certificate showing the rate of VAT charged is Zero Ie - it is zero rated boat (in the UK) as opposed to a standard rated boat. It is not VAT exempt. Correct terminology is very important. Hmmm- why not buy one over there it will be cheaper and have all of the proper documentation - the only problem is that if you bring it back to the UK you will probably have to pay 20% VAT on it.
