  1. Went to our local supplier today, opened boot he saw 13kg empty and said no chance he hasn't been able to get any for weeks. As he is the nearest supplier to two marinas don't sell gas this is going to be a problem I have about 5 weeks before other is empty.
  2. Thanks that is useful to know. I hadn't thought of flooding being a problem as I am used to canal or in the past, tidal marinas where such things as water level change is catered for.
  3. GU you will probably be lock sharing most of the time if you move between 8 am and 1pm. Not many swing bridges or lift bridges unlike the Oxford which is famous for them.
  4. Ouch thanks for that info.
  5. CRT have spent lots of money on two rebrandings in under 10 years, have lost a lot of staff who understood waterway maintenance and have tried to bring the system into the 21st century, by using contractors. Nobody is paid to oversee the wide picture all are looking at their little bit. Towpath renewal paid for by someone else how wonderful but no rings and wall to edge hard surface, what does the boater do who gets something round his prop? Contractors do only what they are paid for and no more, so if they spot a problem which can be solved in 5 minutes, no its not our job, and CRT don't ins
  6. I am thinking of next winter staying in either Sawley or Shardlow marina. Has anyone been in either and can tell me the ins and outs. I will not be living aboard so boat parked and visited a couple of times Covid permitting.
  7. Is that voltage at the charger battery terminals or at the batteries themselves?. If you have used thin wire from the charger to battery there could be a significant volt drop at 15 amps, causing the solar controller to think the batteries are fuller than they are are and switch to float voltage, even though 15 amps shows they are not fully charged. Many MPPT controllers work on voltages and not current, and often have a specific time delay from reaching 14+ volts and switching to float (2 hours) so 9am at this time of year.
  8. I was once moored behind a boat on a nice summer day, enjoying a nice quiet time, after a sumptuous lunch, with the bow doors open. The chap ahead started his traditional single cylinder engine which caused the glasses to rattle on their shelf in my boat, he then locked his door and went to the pub 200 yards away, to sit in the sun with a pint. After 30 minutes I gave up and moved away. He obviously knew his engine was annoying but needed to charge his batteries, if he had offered to buy a pint and have a chat we would have joined him and bought the next round. Instead he has a black mark agai
  9. The common fallacy that MPPT controllers convert volts to charge the batteries, they convert watts. In early morning and late evening series connection does increase the voltage available but as the current available is in the milliamp region so the watts are very small and possibly not enough to actually power the controller. The power loss by partial shading of a panel can be measured in amps so tens or even hundreds of watts. Panels in series will be limited to the amps the most shaded will pass possibly 10% of full sun and easily 50% just having a rope across one, panels in series are limi
  10. Could it be lime scale build up? Most canal water points give very hard water.
  11. My experience is a long time ago 1971 when electronics was a transistor radio sat on the cockpit seat. We were on a wooden boat with a wooden mast, brass main sail slide track and stainless rigging. We never really thought about lightning until a one day when sailing off penalty in the bristol channel there was a b***** great bang and the top 10 foot of the mast fell sideways. The brass track had vaporized down to the hounds where the stainless shrouds were bolted. Presumably the lightning had gone down the shrouds and through the chainplates to the sea. Nobody was hurt but it took us ages to
  12. I doubt the grout would survive the vibration it would tend to return to its dust state.
  13. The low slung bridge outside Tate modern proved that if the bridge vibrated at a frequency near peoples walking footfall then everybody would alter their pace to naturally fall in sync with that frequency, making the wobbly greater hence eventually ever one is in sequence. They had to change its resonance frequency to solve that one.
  14. Not what I have heard. Credit card charged despite telling them you had left which of course they deny, your word against theirs. No objection to paying but I like a user friendly system. Our council has chosen to stop taking cash for parking, you now have to use a mobile app, they patrol it with a camera car. The Phone app. Charges 15% on top of the council fee you don't get a ticket to display or get a fine attached to car, you just get a letter to your house. We are in a tourist area and I expect many of our tourists will arrive home to a nasty surprise. How the silver haired non computer s
  15. Will take 20plus amps in first phase which will last about an hour provided you cooked the food in a pan and pour in hot. Then will average 8 to amps per hour till you eat it. This can mean 60 ish amp hours. Quite a large power consumer. If by cruising you mean engine on not really a problem, we use it a lot but only on days we moved. Cook after breakfast into slow cooker switch on start engine and move off. If you have a largish solar array it will be fine in summer but you don't use them much in warm weather.
  16. Have you estimated the lower potential solar power in the winter months, a rule of thumb is 1/10th of installed potential in December and January. 2.2 Kilowatts on a narrow boat roof suggests zero space for walking along to/from a lock ladder which sometimes is compulsory because you cannot get on the boat any other way and you cannot fit between the boat and the lock wall. I would also suggest two centreline mounting point one on each side by the handrail so the rope doesn't cross any of the solar panels and cause them to lose 60%+ of their power due to shading by the centreline.
  17. It won't work the rule is to sleep at home. Tents boats caravans holiday cottages are not home which is defined as your address as known to tax man and councils for voting. P. S. If you are out Monday pack your thermals.
  18. Oh ready at another nice place gone then. It amazes me that the Thames is becoming so anti boater, I know they had problems near London but it seems as though the cancer is spreading everywhere, the easiest way for a council who gets frequent complaints is always just to shut it down and not police it for the benefit of their locals, many of whom own boats it if they can't easily go away for the weekend what will they do.
  19. When mine was blasted the removed the weed hatch and blasted up the hole they also blasted the bottom plate which sits in the water I don't know if it has a name but it stops the prop wash scouring the weed hatch tunnel.
  20. The main problem I have found on the Thames is 'git gaps' 30 foot gaps between boats, most narrow boats cannot fit, and as most people seem to move in the morning and start mooring about 12-12:30 by 1:00 o'clock it is almost impossible to find a mooring anywhere for a narrowboat. As said many many landowners have put up no mooring signs, due to abuse by long term boaters staying for weeks or leaving mounds of rubbish., they take the easy option which is no mooring. Cookham is a lovely village with several pubs and it has quite a lot of moorings, there is (last time I was there) a nice lady wh
  21. Yes there is and if any surveyor was to use another typr on my boat he would be getting a bill, it was shot blasted, zingered and epoxied at great expense not for some cowboy to grind it off and if lucky, stick some bitumen on in the hope it will stay on when the boat is floated a few hours later. The intruments are not cheap but probably a lot cheaper than a lawyers bill.
  22. How are you measuring the voltage and amps? do you have a battery monitor? If the 12.7 volts was with the engine still on, it is suggesting there is no charge from the alternator at all, is it connected? including the exiter lead with bulb not lit? If it was it just after the engine was stopped, it is still very low the surface charge should last for a good hour or so at 2.3 amps load. It also seems strange that the current drops when you switch the inverter on, often they take and amp or 2 doing nothing but being ready.
  23. BSS regs are relativly mild and mainly aimed at preventing your boat blowing up, or damaging other boats. The Recreational Craft Directive is a different beast altogether, It is aimed at making your boat safe for you and other users, the person who commisions work or does work is responsible in law to ensure it is done to the required standard. All major changes need to be to the required standard. It is the building regulations and electrical/gas standards of the boating world, it potentially has teeth, which can result in a fine or jail for non compliance, but is not well policed, except in
  24. The chances are the red would stop the radiators working as the water will take the easiest path, In my system the calorifier is connected across the flow and return just like the radiators but before the valve so closing the valve cuts off the radiators and still allow water to flow through the calorifier. If your system is as shown with the calorifier in series with the radiators then you either need two valves (one as shown and one on the red pipe) or a changeover (threeway) valve which would be positioned where the red pipe joins the radiator circuit.
  25. I have seen 1/2 inch rope used to form the eye in the concrete, bowline tied in rope knot end into small bucket fill with concrete leaving a half loop sticking out. It is useful to have 2 mudweights, they act as portable ballast to correct the boats trim, in the OP situation drop them 10 foot apart at the bow would stop it swinging, one each end when moored up in an area where the locals think it is fun to untie you at midnight, they can also be deployed on the anchor warp/chain 20 foot from the anchor to reduce the amount of rope you need because they change the angle of pull nearer to the g
