  1. Ah β€” are there no options to the south? I filled up last time at Oxley, but was hoping to head up the Stourbridge Canal instead of doing Aldersley again. Actually, I've just this moment discovered that Sherborne Wharf sell diesel, so I'll probably motor on into Birmingham and sort it out there. Pretty sure the tank isn't that empty...🀞
  2. I'm currently not too far north of Stourton Junction, planning on heading up to the BCN and onwards to the Grand Union. While it's not yet a major concern, I could do with knowing what the diesel options are as they seem quite sparse β€” certainly if the Staffordshire & Worcestershire is anything to judge by β€”and I don't have the fullest of tanks as things stand. Any ideas?
  3. I considered that, but I'm pretty sure my tank is shy of 200L. Been a while since it was filled from empty though, so could easily be wrong! Still, say 140-160L in the tank and 40-60L in jerry cans would work. But it's a shame that having it trucked is obviously less economical overall than being able to buy it canal-side.
  4. I've stopped washing my hair with shampoo entirely, and I can confirm that it feels far better for it after a short initial period of being very greasy. I've always suffered from dandruff, and that has also improved massively. What's more interesting is that, despite having always had healthy/soft/nice hair, I washed it once with shampoo once well established in this routine (to remove some oily boat maintenance awfulness), and it turned awful and dry for a few days. I firmly believe that the body is best at regulating these sorts of things on its own, if you give it a chance.
  5. Are there many boatyards stocking and selling HVO currently? I'd be very willing to change over, but as a continuous cruiser it's not really feasible to buy and store in bulk.
  6. It might make it quieter, but it won't do any good at all for the long-term health of your engine.
  7. Bit rude. It's a discussion forum, not your own personal question-and-answer service.
  8. Or manoeuvre out and however much, however hard and however many times you hit the offending boat...their problem?
  9. ...and you've been spouting the same drivel since halfway through page one, so I felt I wouldn't be missing much by skipping a couple of pages.
  10. I leave it on usually, but I live aboard and go away frequently. If I were away for a longer period, and especially in winter, I'd switch it off to avoid problems like water leaks resulting in 800L of water in the bilge. I really need to add a switch for the water pump... My next project is to install a Cerbo GX to allow remote monitoring and control.
  11. @Timx: I gave up reading this thread after page two, but I suspect the reason you've had such unpleasant reactions to trying to talk to those running engines out of hours is because of your utterly rubbish attitude.
  12. Well, in this specific instance I'd probably look at the 'so many' fenders 'on his roof'. A fender is a piece of working equipment; it's not there to look pretty and quite possibly won't look pretty for very long. It's ridiculous to think the trader in question should swap his perfectly functional fender out as soon as it looks anything other than pristine.
  13. That is cunning indeed. Ending up sideways across the cut so that they ram you. Genius! Also good for making lots of noise and sploshing lots of silty water about as your stern buries itself deeper in the water and onto the aforementioned sticky bottom, eliminating all danger of movement (and happily thus also of ramming).
  14. I wouldn't judge a chef by the sandwich they made for their own lunch; I would judge them by the sandwich they served me for mine. Similarly I wouldn't judge a fender maker by their own stern fender; I would judge them by the 'many' new fenders on their roof that were actually for sale. Why on Earth would anyone do otherwise? Wastage on the basis of aesthetics is asinine, and I say that as someone who is paid to care about aesthetics.
  15. Perhaps because it was still functional, and some people care more or even exclusively about functionality rather than things looking nice? Sensible attitude I'd say β€” after all you're not going to buy a fender on the strength of the gentleman's own fender you're going to buy it on the strength of the ones for sale that you can see and pick up and examine... Why replace something that still works?
  16. Ignoring the sudden queue for Bumblehole Lock this morning, it's pleasant on the Staffordshire & Worcestershire at the minute. There's definitely traffic, but it's certainly not what I'd call busy. Not much moving on the Main Lines last week either β€” saw four boats, all within two minutes of each other, from Wolverhampton to Oozells Street. Hopefully they'll all remain on the Coventry and Oxford
  17. Originally this thought came about from wondering whether one could design an electric propulsion system around a B-Box LVS/LVL installation. A 'full stack' of LVS modules is remarkably close to the peak current requirements of a Lynch Marlin 8kW, which intuitively seems a bit too weedy for a long steel narrowboat β€” and certainly if one want equivalence with their existing engine. This got me wondering about how much power one actually needs, because the obvious comparison is the days of horses. It seemed like an interesting thought experiment. The other obvious benefit is a potentially significant cost saving. I'm not suggesting that anyone actually tries to stick a tiny motor in a big boat, more a case of wondering how much reserve power for manoeuvring one actually needs. People constantly seem to rev the whatevers off their engine making routine manoeuvres, and I'm not convinced it's at all necessary.
  18. Apologies, I haven't really explained myself properly. I don't mean a motor that is undersized for propelling the boat when cruising, I mean I don't think I see the point in fitting whatever the equivalent power motor is to a 38hp (in my case engine), for the reasons that mrsmelly mentions. If you can cruise along at a steady pace using 3kW, I don't really see the need to have a another 17kW in reserve to make up for a lack of anticipation. Obviously you do need excess power, but as boats seem to be over-engined to begin with, I'm not convinced you need anywhere near as much excess power as many people are including when designing electric propulsion systems. It's potentially important if you're designing a system around a proprietary battery system that has a defined peak current that can't be circumvented by throwing more copper at your custom bank of cells. Power seems to be many people's solution (including mine occasionally) to messing up and often even routine manoeuvring; is it not far preferable to just avoid the messing up to begin with, or to think ahead rather than relying on throwing it full aft as you arrive at full speed at the lock landing that was visible quarter of a mile away? Like I said, just a thought, and I'm interested to hear everyone's opinion.
  19. But on the other hand, most leisure boats don't draw anywhere near as much water as a fully-laden working boat. And applying power in shallow water is going to increase your issues, not reduce them. I can't remember the last time I had to motor hard off an obstruction. Actually, that's a lie, I got stuck going through a toll island on the BCN recently. Power didn't help though - what fixed it (quickly and without too much effort) was getting the shaft out. I can't remember a time before that.
  20. The premise is pretty simple, isn't it? Pass line around [bollard/strapping post/etc] and let it out in a controlled fashion. I don't see why passing a mile of boats would be an issue? Again I'm not talking about being towed from the towpath, but having an 'underpowered' boat. There seems to be a lot of focus on what size electric motor can replace a diesel engine, but I'm not convinced, on the still canals, that equivalence is necessary other than for those who try to solve every problem by revving up the engine? I think it'd be quite interesting to install an underpowered motor and give handling it a go.
  21. To simplify it as far as I possibly can; if you cut a tree down and burn it, and replace it with a new tree, that new tree will, give or take, extract as much carbon from the atmosphere as you have created in burning the old tree. Furthermore, the carbon that the old tree sequestered was extracted directly from the atmosphere itself in the very recent past. If both sides of the equation balance, ie the source of the wood is sustainable, then all that is happening is that the carbon already present is being recycled in a constant loop. It's a balanced equation. If you dig up coal and burn it, you are releasing fresh carbon into the atmosphere that would otherwise never have been released. That is a huge and fundamental difference. It's adding new carbon to the atmosphere. Burning wood is not adding any 'new' carbon to the atmosphere. The issue isn't that there's CO2 in the atmosphere; the issue is that we're adding huge amounts of CO2 to the atmosphere that was previously permanently stored in solid form within the Earth. I can't put it any more simply than that; it's very basic science, it's taught at KS3. If you can't get your head around it and want to pretend that all is bad and therefore it's pointless trying to make a difference, I can't help you. I've also yet to find a carbon-negative method of heating, but please do tell me if you come up with something.
  22. The carbon released from burning coal was sequestered millions of years ago. The carbon released from burning wood is equivalent to the carbon 'stored' by the tree from the atmosphere within its own lifetime. And so of course wood is better - you're generating no 'new' carbon, you're only reconverting back to the atmosphere what the tree has taken in from the atmosphere through photosynthesis. If the wood is sustainably sourced, it is thus effectively carbon neutral.
  23. I don't mean in the sense of towing - I mean in the sense of learning how to handle a boat that is limited in manoeuvrability. Recycling past techniques like strapping the boat to a stop coming into a lock, etc. Not relying on having an extra 37 horses (so to speak) to get one out of tricky situations, but rather avoiding getting into them in the first place. That said, judging by the hire boat that smacked me yesterday and actually dented my hull, maybe that is a silly and dangerous idea...
  24. I've been musing about electric boats a lot recently, as I'm planning my own long-term conversion. One thing that I can't help but think, when people compare electric motors versus diesel engines, is that boats were moved perfectly well in times of yore by a single horse. No aft gear, no massive excess thrust on demand. On the canals at least, would it really be such an issue to go back to more traditional boat-handling techniques rather than relying on excess thrust on tap to manoeuvre and fix sticky situations? Obviously beating upstream on a flowing river is a different matter - but many will never end up in that environment in the first place. Just a thought.
