    Hi all My first post on this forum. I don't have a canal boat but enjoy walking along canals and sometimes chatting to boaters / helping them lock. On Monday night 14/9 I found a satellite dish in its case (open) on the towpath and want to try to reunite it with its owner. It's from Travel Sat and I called Martin the owner of this business via the mobile no shown, thinking he might be able to look up the person he sold it to via the serial no BUT these dishes don't have them and he's sold about 1000! Martin was very helpful in talking me through checking and assembling this thing via WhatsApp video and we have ascertained that it's all present and correct apart from a missing screw (1 of 4) on the mounting bracket and a minor broken lug on the bracket - neither of which stop it from working, just need to be more gentle when tightening the knurled wheel acc to Martin. If you think this might be yours, contact me to tell me where you lost it. There are also some accessories in the box with it which acc to Martin aren't standard but are extra. What are these? Mark

    On a budget is not the same as dishonest. The people who take these things are just thieving scumbags , its not like stealing food because they are starving to death.

    I agree with all but one thing. Although a surveyor can't say anything definitive about battery sulphation or even cell shorts if he knew his stuff he should be able to spot and report on indications of such faults (battery design allowing). Bowing case ends or lifting cell tops indicate a serious degree of sulphation while individual dry cells are fairly indicative of that cell gassing excessively so may well have internal shorts. having said that I bet few bother to look, mine certainly did not so its down to the potential owner if getting new may be an issue.

    He’s right though. Unless the batteries have been recently replaced, budget to replace them. A surveyor won’t be able to check their capacity so anything he says about them is worthless.

    The higher end of the market maybe, but the type stolen in urban areas from boats usually end up on the canal bed a few yards away, especially if like Lady G's they can't even be ridden. I get pestered by scum trying to sell stolen bikes where I work in Sheffield, sometimes for as little as £10. I'll often see the bike left leaning on a wall somewhere nearby when they've got bored of wheeling it around with the sales pitch "do you want a mountain bike pal? It's 500 quids worth but you can have it for 20" One of the regular shits turned up with a set of triple aluminium ladders once which I could have for £25. There was probably some poor bugger stuck on a roof up the road!

    The description of what happens during charge and discharge is pretty much on all fours with the description in a 1940's specialist textbook on accumulator charging. At thst time it was common practuce to recharge accummulators from DC mains via a lamp board, the number and wattage of the lamps determining the charging current. Charging would continue untill all cells in a battery were gassing freely, meaning that all cells were able to attain a fully charged state in which even the sulphate in the deepest layers of active material would get converted. It was considered safe to discharge down to 1.8V per cell: deeper discharge would result in the production of hard crystalline sulphate having a different crystal structure to the sulphate produced at higher discharge voltages, and it is the hard sulphate that is virtually impossible to convert back. The voltage drop at high current discharges is due to the sulphuric acid reacting with the plates by giving up its sulphur; the reaction generates water which dilutes the acid near the plates and hence affects the chemical reaction that generates the current. Allowing the battery to rest allows fresh concentrated acid to diffuse into the active material, thereby raising the voltage again. I don't think that sort of constant current charging is practiced much these days. Charging until the voltage reaches a value indicative of full charge is fine if all cells are balanced. However, the voltage of a weak cell can rise to a higher level than the other cells, thereby tricking the control circuitry into terminating the charge cycle before the other cells are fully charged. Installing a solar charger is a good move. In a recent post of another thread the poster reported that his boat was fitted with solar panels last year, and that after several months of non-use, his batteries, which his instruments had indicated had lost a significant amount of their original capacity before the perid of non-use, were now being indicated as in good condition. Possibly the enforced period of resting had allowed the conversion of the deeper regions of the active material to be regenerated as there would have been plenty of time for the electrolyte to diffuse into the deepest sulphate layers, allowing them to become converted. Trickle charging at a low current is known to be a good way of keeping a battery in good order, but is not practical in a canal boat whose battery is used every day. Rapid charging of really heavily discharged batteries is not recommended for ordinary batteries: the resulting high current density in the conductive regions of the plates between the higher resistance sulphated regions will give rise to differential thermal expansion between sulphated and non-sulphated regions, resulting in shedding of active plate material and loss of capacity. Trickle charging keeps the current density and temperature rise low, reducing the likelihood of shedding active material.

    A lot of people don't seem to realise that a 'sailaway' is now (since 2017) subject to the full RCD requirements no Annex iii(a) can now be issued. The new Directive has effectively put an end to Sailaway boats (completed to all variety of levels) being supplied with an Annex lll(a) Declaration as was previously possible under Directive 94/25/EU. Under the new Directive (2013/53/EU) Sailaways (including hull only) would need to be supplied as completed craft. Therefore for anyone purchasing a narrow boat sailaway from 18th January 2017 must ensure you have the necessary paperwork from your boat builder that is required of a ‘completed’ craft up to the current point of completion, this includes: A builders plate – makers details and technical information A CE mark A Craft or Hull Identification Number (CIN or HIN) – it is carried in two places on the boat; one should be hidden for security. An owners manual with information needed to use and maintain the boat safety A declaration of conformity (DoC) A CE marked craft shows the craft is compliant when it was placed on the market for the first time. It remains valid unless a major alteration to the craft takes place which would require a re-assessment of the craft. ‘Major Craft Conversion’ would be applicable to the fit out of the majority of sailaway boats, and needs to be factored in when planning your fit out. Once you have completed the fit out of your sailway boat, the boat would require a Post Construction Assessment by a qualified surveyor / RCD Examiner and the documentation, builders plate and CE markings all need to be updated. Although a self assessment is possible, it is not recommended as the fitter would resume all responsibility as the manufacturer and it is also a lengthy and involved process. In the worse case scenario, it could mean you are held criminally responsible if the boat sank and there was loss of life. It is recommended that you appoint a professional to complete the post construction assessment, this would be at of cost of around £2000. If a company is being paid to fit out the boat, is it still a self build or a commercial operation - It becomes a question of 'degree' who is doing the majority of the build ? If the OP is buying a 'built sailaway', and then paying a company to do all the 'fitting out' (except 'walls' and carrying the furniture on board) then I'd suggest that it cannot be classified as a 'self-build'. The OP becomes the 'project manager' but is not the 'builder' and the 'builder' is not building it for personal use. The OP can used 'specialist' labour where needed but doing 'all the work' ................................. ?

    I tried to get rid of an old bike, left it on the roof for ages, went around the network etc.. Nope not got nicked, so I left it on the towpath for anyone to keep. Four days later someone returned the bike to me thinking I had lost it. Next time I will padlock it, with a chain, someone is bound to nick it then.

    You are answering a point I have not raised, I don't blame you for this😀 I would hope that there are several level sensors so the system should have spotted a major event, and it presumably gave a consistent trend over two hours. Putting all this type of stuff on the internet is just daft, its not just the Russians, I expect a load of spotty schoolkids would love to play with this sort of infrastructure. A separate topic for debate if we ever manage to meet for a beer, was this software created by computer scientists or engineers? As an engineer I have always believed that if I ever do something recklessly negligent then I take the blame and professional insurance wont save me??? .............Dave

    Indeed. However its an interesting side discussion for those with an interest in the history of our waterways. It in no way detracts from the damage caused. At least no lives were lost which is something.

    A boat is chock full of systems, frequently everything that a house has but smaller, more inaccessible, of rare and unusual design and on my boat no professional has had a hand in putting it all together. It also runs on 12 volt with a bit of 240 here and there , the heating is unusual - paraffin - and the engine is nearer the front than the back. Crammed into most boats is an ex automotive or plant engine and coupled to the propeller by a frequently poorly installed gearbox and various couplings. All this is contained in a hull that is impossible to inspect on the inside and not easy to interpret on the outside. Also in this challenging structure is enough gas to destroy a medium sized house, enough amps to melt big chunks of metal and enough diesel to make a very hot thing even hotter. Pity the poor old surveyor who inspects this expensive assemblage and misses a corroded jubilee clip or missing split pin that sinks the whole lot. As MrsM says, check as much as you can and it really is in our own interest to familiarise ourselves with our boats. There, That'll put everybody off buying a boat and make a bit more space on the cut.

    Yes, the whole thing, Reading to Bristol, is correctly called the Kennet and Avon Navigation. I don't think there is such a thing as the K&A canal, though the term is increasingly used, it could be used to refer to the man made section between Newbury and Bath, though this also includes a few sections of River Kennet. Most likely the term "canal" is used by people who don't understand the difference between a canal and navigable river, which is not always a clear distinction. I note that the CRT "carved graffiti" on a Birmingham lock refers to a river so its an easy mistake to make 😀 ..................Dave

    I was in the shower moored on the Thames when someone nicked the bike off the roof about 4 pm. He dropped it when he realised not only was there no seat but the handlebars were 90 deg to the front wheel.

    Hi Please can anyone help/ advise. We are having to paint our boat and conscious of the variety of weather we will be having. As the boat is coming out to be blacked thought we would cover and paint at the same time. Any advice with regards to covering ie purchase, hire or make. Had a quote for £1250😢 Thankyou

    This is why I said pure sine wave. I get hum over the speakers when I run things from the cheapo emergency backup inverter the couple of times when the posh Victron throws a tantrum. There are higher frequency harmonics in the modified sine wave that can get through to the speakers sometimes. Jen

    It confuses the volockies at Fradley when I reverse down junction lock. Last time the lady off the boat coming up looked very confused and asked if we were going down or up.

    It doesn’t actually matter that much what the D.C. voltage is. You can get 12V adaptors that supply all sorts of voltages.

    Nigh on two years, turned out agent sent out a survey which mentioned flooding, so no one bothered to view. I only found this out when I tried to insure it!. I had had a burst pipe, and refused to sign off the survey report which mentioned 'flooding', but the agent used it anyway. The flat was at the top of a hill!

    I think this is a bad idea......for all of the reasons above and especially the horrid switching arrangement that would be needed which could fund another battery to make it 5 in the bank! I'd like to throw in 2 other inputs. First, why are you thinking of this idea? If it is that you are not charging your batteries properly now, then how is this going to make it better? One battery might get charged properly once per month (but maybe not Nov – Feb!) but the other 3 will have 3 weeks where you are not taking them to full – because your 'ace' plan of charging one every month is good. 3 weeks is too long time without full charge and sulphation will take place. See below. You will get lulled into a false sense of security - I dont have to worry about my batteries not getting to 100% as they will be fully charged by solar in 3 weeks time! Secondly, there is a technical input. Now, I am not a battery expert, but I am a trained chemist and see a big problem. This isnt something I have seen written about, but as a chemist I understand chemical reactions and what makes them happen and battery chemistry is no different. I would happily debate the following with anyone. A typical lead acid battery is designed with it's plates having a very large surface area. The surface area is increased by having 'pores' in the plates. The production of electrons from the plates is a surface reaction and needs chemical species to travel to that 'site' on the surface or deep in the pores to complete that reaction. On discharge from full, the first electrons appear as a surface charge. It is very easy for each 'site' on the 'easy to get at' surface to give up its electron in the chemical reaction. Once the surface charge is gone then the next 10% of charge out of the battery comes from sites very near the tops of the pores. Lets call them the 90% sites. When the next 10% charge comes out (so the SoC is dropping from 90% to 80%), it is more difficult for the chemical reaction to happen as the reaction is likely in the pores themselves and some of the energy released is needed to provide the activation energy to make the electron releasing reaction take place. (Is this why the voltage drops with SoC????). Anywho, this goes on down until we get to say 50% SoC. By this time, the chemical reaction is taking place half way down the pores so steric hinderance is a key issue and the reaction is much slower needing a bigger activation energy for the 50% sites. Ok that is discharge. We now charge back up. Which sites get converted back first? The 99% or 100% sites on the surface or the 50% sites deep down the pores? From a chemical point of view it is certain it is the 100% sites as they are not sterically hindered and need the least activation energy to turn the lead sulphate back to lead. Once they are full, the charge then does the 90% sites, then the 80% sites and so on. The last sites to be converted as the SoC approaches 100% are the 50% sites deep in the pores and this is why everyone says you must charge with 14.4V. You need the high voltage to provide the high activation energy. Charging the easy to get at sites which give up their electrons easily when discharging from full, charge back up easily with just over 13 Volts unlike the sites deep in the pores. How does this affect my charging then? Well in the OPs case of discharging 3 batteries and only getting up to 100% charge on one offline battery every 4 week, then discharging to 50% and only say getting back to 95% means that the 5% deficit of sites deep in the pores are not going to see a charge until their turn for the 4 week solar boost and will certainly form a hard sulphate deposit that will be very very difficult to remove. Is solar really going to hack it and get the high volatage in to convert that sulphate? Me?, I'd sooner invest in the 4th battery to make my bank bigger so instead of discharging to 50%, I would only be discharging to 63% (ish) and maybe spend all the money you are using on switches to get 5 batteries so discharging to only 70%. All the battery companies show the number of cycles to death increasing for less discharge but these figures usually do not take into account sulphation. The need for higher activation energies for the sterically hindered sites deep in the pores though means that they must be more difficult to react so sulphation will be a key input. Put the biggest bank in you can for longest life. You've got more chance of avoiding sulphation by not discharging as deeply therefore needing less energy to recharge that last 1% of capacity deep in the pores. Problem is, have you got room for 5 batteries? Who's got the popcorn?

    The rear deck itself would never be big enough to be able to swing the tiller through it’s full arc on a trad but it must always be possible if standing on the step. Otherwise you wouldn’t be able to steer it at all. The problem only arises on trads when the steerer steps back from the step. In reality it shouldn’t be much different but of course if you aren’t on the step you have far fewer options for avoiding a swinging tiller on a trad than a cruiser stern.

    Henley on Thames a few years ago, some Pillocks nicked a broom of the roof, heard 'em do it too, some posh kids by the sound of the accents, One was called 'Gove' 'cos the other one was braying like a donkey chortling 'well done Govey' and 'Govey' replied 'Jolly good jape eh Boris,, Wonder what happened to the theiving little gits.

    It is generally done very slowly usually by pump , and the bund is left in place whilst it fills. Then 2 weeks minimum with no water being let in to test the waterproofness of the construction. Only then is the bund removed...very unspectacular.
