Is it staying dry now, or will you have to wait for middle of winter again to assess?

I'm not arguing with you, Dr. Bob - My post was an enquiry. If your recommendation is 14V based on addition of cell values rather than multiplication of cell values, I understand your concerns. What I didn't state, and perhaps I should have, is that my BMS controls both individual cell voltages and pack voltages - any anomaly in either results in protection. So, I have my cells set at 3.75V and my 8S pack at 30V - either limits a dangerous situation. And as Nick has pointed out my chemistry includes yttrium, so my limits may not apply to other LifePO batteries.

I think you are further confusing the issue. My term "Recommended maximum voltage" and your term "maximum recommended voltage" are not the same terms. You are misquoting me, as well.

I can't understand pigheadedness - the term "maximum" is what is you're missing MtB. None of your replies include that. You choose to ignore it.

Please do not ascribe bullshit to my name. Read my post carefully. Then, if you wish to quote what I said; you can cut and paste exactly what I said.

I don't know where 14V comes into a "dangerous" zone in the case of my Winston cells - The supplier recommends a maximum charge of 4V per cell which is 16V if I understand maths correctly? https://files.gwl.eu/inc/_doc/attach/StoItem/3861/ThunderSky-Winston-LIFEPO4-100Ah-WIDE-Datasheet.pdf

I took a simpler route for my LiPo4 bank. I don't charge them via alternator. Solar only. And a genny for winter necessity.

That would certainly end my boating days...or all my days.

You might be thinking of Nitrogen?

You'd only need to rest them on a couple of match sticks to allow the cold air out?

I recently discovered some mould in the back of a cupboard - it's against the lining of the cabin about a couple of inches above the floor - behind the lining is a gap between the edge of the floor and the spray-foam insulation. I think the cold air in the bilge is causing condensation to form in this area, leading to the mould. So, I have some questions...is this gap to allow ventilation to the bilge - what would happen if I closed this gap with more spray foam? - just the area behind the lining of the cupboard - bear in mind the other side of the barge would still have the opening. Would it be better to have vents in the cupboard panels to draft more air through this area? Or both? It's easy to remove and attach the cupboard and lining for access. The other thought I had was in how the bilges are constructed - reinforcing cross-members span the bottom plate - channels are cut to allow water flow to the rear of the vessel - for water...but the top of the cross member is used as a platform to support a batten that supports the floor - the battens, as far as I can ascertain are not notched to allow air to circulated - so each reinforced "cell" between the supports does not have good air-flow barring the side sections, which as I have mentioned allow the cold air to cause mould on the cabin lining inside the cupboard... What about sealing the entire interior floor section - airtight, then dropping in Argon gas to prevent mould and as an anti-rust? I imagine it would be simple enough to fit a membrane under the floor, with a gas valve to introduce the Argon? Because Argon is heavier than air, it should stay there and topping up would be a simple affair, when needed? Any thoughts?

I recently had my Chinese diesel air heater also run badly - unlike yours, mine was white smoke and not starting at all. I disassembled the burn chamber and found it to be clogged with carbon. After a good scrape out, it is back to normal - I have adjusted the pump and fan speeds to try to lean out the burn to prevent this from happening again - this was after a year of running. You may have a fuelling issue too, but you may have caught it earlier than I did. I suspect mine would have gone through a smoking phase before it failed on ignition.

The argument here isn't really how coal was formed, rather it is whether coal is still forming. As the Wiki page tells us - 90% of the coal formed in a specific prehistoric period when certain conditions were favourable. Those conditions since that period have been sporadic and intermittent since, the coal seams found around the world point to this.

Although coal is known from most geologic periods, 90% of all coal beds were deposited in the Carboniferous and Permian periods, which represent just 2% of the Earth's geologic history.[21] Paradoxically, this was during the Late Paleozoic icehouse, a time of global glaciation. However, the drop in global sea level accompanying the glaciation exposed continental shelfs that had previously been submerged, and to these were added wide river deltas produced by increased erosion due to the drop in base level. These widespread areas of wetlands provided ideal conditions for coal formation.[22] The rapid formation of coal ended with the coal gap in the Permian–Triassic extinction event, where coal is rare.[23] Favorable geography alone does not explain the extensive Carboniferous coal beds.[24] Other factors contributing to rapid coal deposition were high oxygen levels, above 30%, that promoted intense wildfires and formation of charcoal that was all but indigestible by decomposing organisms; high carbon dioxide levels that promoted plant growth; and the nature of Carboniferous forests, which included lycophyte trees whose determinate growth meant that carbon was not tied up in heartwood of living trees for long periods.[25] One theory suggested that about 360 million years ago, some plants evolved the ability to produce lignin, a complex polymer that made their cellulose stems much harder and more woody. The ability to produce lignin led to the evolution of the first trees. But bacteria and fungi did not immediately evolve the ability to decompose lignin, so the wood did not fully decay but became buried under sediment, eventually turning into coal. About 300 million years ago, mushrooms and other fungi developed this ability, ending the main coal-formation period of earth's history.[26] However, a 2016 study largely refuted this idea, finding extensive evidence of lignin degradation during the Carboniferous, and that shifts in lignin abundance had no impact on coal formation. They suggested that climatic and tectonic factors were a more plausible explanation.[27]

Er, no, it's not. Coal was formed before evolution developed bacteria to break down dead matter. Once that happened, no more coal.

Best way to learn boats is to go dinghy sailing... Yes, I know it has extra things like sails to learn, but as a fun, fast learning curve, it can't be beaten... Tiller steering becomes second nature, and learning boat handling in windy conditions is an added experience that can hold you in good stead on the cut.

I used Aluminium Rivnuts - polymer sealant on drilled hole and on bolt threads - I thought aluminium won't rust and the threads would not bind when I can to remove them - bolts are stainless too. I may have over thought this but I hate seeing these cheap galvanised bolts from the hardware stores that rust a bright orange in a few months.

I think you'll find the take off points for our diesel lines will be somewhat close to the bottom of the tank - any water in there will be sucked up as soon as there's enough to get to that level.

From edge to edge I measure 200mm. I'm not sure the actual hole size.

Interestingly, Collingwood do an inspection hatch with integrated fuel filler and cap.
