There was a lengthy post about 6 months ago on this, link attached, perhaps you could contact the OP to see how they resolved it. https://www.canalworld.net/forums/index.php?/topic/115288-insurance-question/

New boat prices went up 20% or more 2020 to 2022.

A turbine at that size spinning fast would create a large gyroscopic load if you tried to turn it through 90degree, so harder work than expected.

Also a lot of boats do not have a straight filler pipe to pass this down.

Previous consultation emails have gone out over a few days so I wouldn't worry about being ignored quite yet, I have not had mine yet.

Normally the smaller one is for the engine starter battery, often also charges the bow thruster battery via a voltage sensitive relay. Normally the 175A one charges the domestic battery bank.

If you enable the motorhome screen on the Cerbo GX you get a screen similar to that below, tap on the AC current limit and you can alter it with immediate effect, no need for accessing the set up.

Victron categorically state that ESS should not be used for off grid install such as boats. ESS relies on a permanent grid connection and at times can feed energy back into the grid, especially if a large load is turned off. I do not know if the travel power electronics would like being back fed. I believe ESS also needs a grid code to be set on the inverter so the system knows the rules. I am not sure you needs ESS, you just needs the AC current limit setting so you do not draw too much power. If you have a Cerbo GX connected to the inverter then you can set the AC current limit from one of the Cerbo screens very quickly and easily without needing to reprogram the inverter.

They do not communicate with the charging system, they are standalone and just isolate the battery from the system. The 12V group advocates these for the hybrid setup with a lead acid left in parallel so the alternator or other charger does not suddenly loose its power sink and give a voltage spike.

If Stenson lock is closed is there a shortage of water travelling downstream. I have no idea if there are any other feeds between Stenson and Shardlow.

We spent a few days there in June, moored in the Oozells Street loop VM, no shortage of space in the area.

Is the boat a residential boat, i.e. a liveaboard. If it is then the gas work should be done by a gas safe fitter with LPG and boat acreditation. I have no idea if this would cover running a pipe but not making any joints or connection of appliances.

The gearbox dipstick is integral with the filler plug, the brass nut seen in the lower left corner of the gearbox in the photo above. When you remove the plug there should be a 150mm long steel rod about 4mm diameter attached to the nut with marks on the lower end for the oil range.

How about when the whole boat lifts up as it goes over the obligatory washing machine on the Rochdale creating a significant point load.

Carling Galore !!!

Time to get your multimeter out and check if there is power at the fridge to eliminate that as a problem.

We have one of these in the galley mushroom vent and one in the shower room. 12V light and fan

Timing lately has been critical, we sold our old boat early 2020 and then cursed because later that year prices increased. We signed the contract for our new build in early 2020 and cursed when lockdowns put delivery back from Oct 2020 to April 2021. We thanked our luck with the timing when new boat prices escalated significantly through 2020 and 202, we were probably one of the last boats through the builder before escalation or availability problems.

12ft widebeam, isn't that going to make it a wide load so transport firm will need to do more planning and notification of the authorities. For questions of mooring in London, join the London Boaters Facebook group, they probably have more up to date / local info.

The price rises over the past year or two have a lot to do with it. 2020 would give you a boat with a much higher spec for £170,000, with top quality crafted joinery and fit out. Those £170,000 boats are now £205,000 due to raw material increases. 3 years ago it would have been a £135,000 boat.

Enlarging the photo it does not look like solid bus bars along the whole length but a series of short interlinks between each adjacent battery, so a double interlink connection at most battery terminals in the daisy chain.

For the avoidance of doubt I meant The measured total voltage is not necessarily the mathematical sum of the 4 measured voltages because the BMS may use a different sensor for the total voltage and not just add up the 4 individual voltages. I thought this would be understood from the context.

The individual cell voltages and total cell voltage may be being measured by different sensors which have their own inaccuracies and may therefore read slightly different. The total voltage is not necessarily the mathematical sum of the 4 cell voltages.

As you are in Burton on Trent have a look at Aqua Narrowboats, they are based in Foston on the A50 so not far away. Good record of fitting out boats over a number of years.

Perhaps they have closed on line purchasing for Christmas Hols, banner at the top says open on the 4th.
