Yes, lot of nice places around there.Apparently Einstein spent some time just outside cromer too. Dunno if he was there for the crabbing though. He did like boats though, and probably would have approved of this: https://myelectricsparks.com/yamaha-introduces-worlds-first-hydrogen-powered-outboard-engine-miami-boat-show/ BTW The PLA is looking for a deputy harbour master. I heard you might be looking for a job, so have put your name forward.

He nicked it off a dalek

I guess boats will be moving to Blakeney then, which last I looked is a free harbour.

TL;DR When we was young and fab. We bought our boat from Cowroast marina some 25 years ago last week. Twas before the days of Internet forums and the thousands of you tube videos extolling the many virtues of canal boat ownership. It was thus,with ignorant bliss, armed with only a week's hire boat experience between us and the enthusiasm that only youth seems to provide, that we came to own a rather neglected 70ft narrowboat and jumped into the muddy ditch feet first, with eyes wide shut. Unfortunately for us, though we had a hull survey,we were about to be faced with the harsh reality of boat dwelling in winter without any heating. We had, somewhat prematurely, handed in our notice on the tiny cosy flat which we had been renting,that would have protected us quite nicely from the remaining winter.Having moved out of the shelter of the marina, the honeymoon period plugged into the umbilical and the fan heater connected to it was soon a distant memory. We spent the first two weeks moored outside the marina entrance, frequenting the Cowroast pub every night, soaking up its warmth, and hoping to take some back with us to the freezing boat, Staying to the final moments, hoping the bar staff could see the desperation in our eyes and take pity on us. That night, after slipping into our woefully inadequate sleeping bags, we were greeted by a strange new sound, which turned out later to be the canal freezing over. After a week or so, with the canal still frozen,our now full toilet tank and empty water tank, no gas and no heating, I was beginning to think we may have made a serious mistake with this boating business. We had somewhat stupidly bought the boat without a mooring,and for some reason, that escapes me now decided not to stay in the marina. We spent the next week traipsing up and down frozen towpaths in search of moorings, only to be greeted with looks of pity as those in the know kindly informed us that we should have sorted out a mooring before buying the boat. We eventually happened across a scruffy boatyard next to a somewhat lovely little pub and quite noisy railway line where we were introduced to a couple of characters the locals referred to as the two Kevs. We must have looked despondent and freezing, as the Kevs took pity on us and found us a mooring. We spent the next few years fitting out the boat and travelling the stretch of canal between London and Braunston, often stopping at the curry pub at Bulbourne and the various pubs enroute in Berkhamsted. Tring summit was, for the first year,a regular cruise as we took various family members, who thought we were mad,for a ride. Visited Bulbourne yard on a number of occasions marveling at the skill and sheer size of the work undertaken there. Happy memories of Cowroast, even though it was grim at the time.

I'm sure you know all this, being an electronic genius, however I thought I would share it here anyway. Whilst investigating my optimum tail current termination valuation vs absorption voltage, I came across this quote from nordkyn: From this page on tinterweb https://nordkyndesign.com/charging-marine-lithium-battery-banks/

Appy birthfay for April. 25 years for us last week.Same boat.

Yes. My LA has a recommended absorbtion of 14.4V. I tend to stick it on the battery charger once a week and isolate the LI to satisfy that requirement, though understand it is less than ideal.

Maybe I'll just ditch the LA. Seems so much easier.

Ok. Thanks. The absorbtion is usually set between 13.9 and 14.1 Volts for a 10 minute duration. So, if I want to use the tail current setting, it should be set to 5% of my 280Ahr LI + 100 Ahr LA bank = 19 A, or 5 % of 280Ahr = 14A? The chargers are capable of 30A each, and there are 2. Thanks. Yes, I remember reading that just before I put my own settings in. Dunno what fogstar recommend, I don't have one of their batteries or cells (yet).

Anyway, a question for you Lithium experts. I have since recently had the tail current function settings on my Victron mppt controllers set to off. I just turned it on with a 1% of nominal capacity setting of 3A. Is this: A}Right B} Wrong C} There is no right or wrong or D} Nobody gives a shit? They must have changed it since I asked the guy at fogstar then, because he said it could.That was with a JBD BMS. Quote from Fogstar when I asked in 2022:

I was under the impression the Fogstar BMS could be set with user defined parameters, so If top balancing is required, the voltage settings can be altered. Though I thought you said earlier with well matched cells that have already been properly balanced, it wouldn't need doing.

What you need is a LA in parallel with a switch between.That way, you can leave the solar to charge the LA whilst isolating the partially charged lithium. When you return, charge the LI from the LA. Sorted.😂

Shirly one would just increase the absorption voltage in the summer months, and disconnect the solar when not in use. Unless you need it for your caravan bilge pump perhaps.

Gloves?

What's wrong with a bucket lad, or just wash your hands in th river. You could even empty the contents of the bowl over the side by simply lifting it.. Frankly ,i'm amazed you want to wash your hands anyway. Anyone would think there's a woman involved here.

I expect it will rise to the occasion Currant bread is rather nice

......or fit your calorfiier with a thermostatic valve that controls the temperature to all taps and shower.

I would agree with everything that had already been said above. We have both an instantaneous gas water heater and a calorifier on our boat, suitably valved such that we can switch between the two. The calorifier has a thermostatic valve on the output such that the temperature can be set so not to be too hot. The use of a gas water heater will consume quite a bit of gas, so make sure your bottles are adequately sized, and ideally available at the marina at short notice if you don't have a spare. Similarly, the calorifier will need to be big enough for everyone onboard, or showers staggered so that water has time to heat up again. We have both a paloma and a rinnai (on separate boats) , and I much prefer the paloma. Be aware that as the temperature in the winter drops, you may need to increase the temperature selector on the heater, which in turn reduces the flow rate. Showers in winter with gas water heaters are not as good as those using the calorifier.

I'm not surprised it has failed if in continuous use for such a long period of time. I'm not sure they are designed to be used in an uninterrupted manner.

I mean as safe as it can be for the set of guidelines and training that they must adhere to in order to be granted the status of boat safety inspector. That, which I would hope would surpass my own knowlege and that of my clueless neighbour.

Well, yes, but I would expect the opinion of the boat safety inspectors are guided by knowlegeable guidlines which surpass my own. They are afterall trained. I pay rather a lot of money to have my boat checked for safety, so would hope that for at least 1 day every 1460 it is safe for at least 2 hours of that day. Point taken about your boat, but I think it unfair that you introduce cars into the discussion. The boat safety scheme concerns the safety of boats surely, not the people. Clues in the name. We don't have the equivalent car safety scheme, its called an MOT. No mention of safety at all.
