    Rudder ladder

    I would consult the shell fabricator on this. Presumably they have some understanding of vessel handling characteristics and rudder dimensions. It will all be in the plans. Along with things like tons per inch immersion and metacentric height.
  2. Indeed, living on boats is totally different from land. They even have a different word for getting rid of you You get no security. Ok so you also get no security with rental but the difference is that when you get evicted from rental you only have yourself and belongings to move but when you get 'eviceted' from towpath you have the problem of a boat to remove. If you don't remove it then the navigation authority will do it for you. And yes, they do. Apologies for making light of a spelling error.
  3. I think you missed the point I was making but never mind. If there is to be a major change to the way boats are propelled then is there any reason to think there won't be a major change to the way boats are hired? I could see 1,2 or 3 day hires becoming popular and never mind the rings just enjoy the thing about moving across water, quietly.
  4. Electric boat propulsion also has a positive psychological effect in that you start to enjoy the process of moving over water as there is no droning noise. And you don't feel the "endless miles" entitlement that comes with diesel engines. At the moment electric is a significant minority but over time that will change and eventually we will have a situation where nobody is in a hurry to get anywhere and all inland boats will move around at the same sort of speed as ducks. Obviously ducks also fly very fast but in boat terms there is fundamentally no need to travel at anything more than about 2mph. If, and it is a big if, all canal boats were limited to this 2mph by range anxiety then the whole thing would work better.
  5. That looks like a neverspacher to me. The best way to show a .pdf would be to provide a link to where it is online.. If it's not online somewhere then be suspicious..
  6. Yes and probably strict controls on moorings. None of that cc ing nonsense. £25 seems rather cheap for a week.
  7. The now defunct supermarket "Kwik Save" was named after a Mr Kwik.
  8. I don't expect that the man with the 130m megayacht which takes 20 road tankers to fill up will have any problems getting hold of diesel in the near future. Whether consuming 100,000 times more than your average human is "modest" is obviously a tricky question.
  9. That last bit is why I would be keeping the diesel engine and building a small pod motor into the rudder for slow speed manueouvering. Slight disagreement about torque curve not being relevant because the simple fact is when boating on canals there is quite a lot of getting boat up to speed for example after locks. Diesels are not ideal for this. A well propped electric motor is ideal for this. It seems quite popular on buses to use electric to take up the initial load of acceleration followed by clutching in the diesel power unit. Canal boats are small but it's definitely a good strategy to do a similar thing. You could turn the diesel engine off five minutes before arriving at a lock and back on 5 minutes after leaving. But I would not personally want the agro of having both power units on the same driveline. I think a folding prop could prove useful for the electric pod, and learn to approach locks slowly and use strapping lines rather than waste power with reversing. All the time with the knowledge that the diesel engine is there on the button as and when needed.
  10. That's pretty good and that's on a 30 tonne 57x12 boat if I remember right. It is remarkable how much less KW you need with electric due to the torque curve situation but it is also remarkable how effective range anxiety is at making the boating less pleasant especially if you do boating without having any advance plans ie just get on with it and see how it goes. This is usually how I do boating and if sometimes results in rather long days the longest this year being 15 hours with two 20 minute stops. Having said that a fair amount was locks and it's when you have a lot of locks that electric will really shine through as the most incredibly sensible way to be doing it.
  11. Or a big wheel reaching down to the canal bed? (Unable to remove quote of the happy nomad not sure why)
  12. Yes 4kw is about right I reckon which is why I got a price for an Aquamot trend 4.3 pod motor. £3k approx. Not too bad. I already own an Aquamot trend 1.1 outboard and am very happy with the product build quality. It's a good item. Yes I saw that.
  13. All leisure will be banned eventually Once you start letting the I'm the world's number 1 fan of electric boats but I really don't think 2kwh will go far propelling a 50ft narrow boat. I have done some experiments with my 40x9ft canal boat and yes a 1kw pod motor will move it but you would want slightly more power on balance and obviously some people like to do more than an hour or two per day. It will be excellent when it all comes together and works, which it will. I'm sure these same discussions, optimism and pessimism were had during the transition from steam to diesel power. And probably the horses too. Silent boating (not all electric boats are silent) is definitely pleasant in a big way. I've been doing the math and I reckon for about ten grand I can fit a 4kw pod motor to the rudder, install a decent amount of lifepo4 battery and a couple of KW of solar. Certain amount of DIY needed. That will give me a very effective -secondary- propulsion system which may over time become a feasible primary system. However I reckon taking out the dinosaur oil unit is not sensible just yet.
  14. Maybe what will happen in reality is that pleasure boating or living cheaply on boats will simply be taken out of the equation as not necessary for society to function. If this climate thing does start to kick in properly then surely there will be a lot of activities which we can currently enjoy which will be sidelined in favour of those things which people actually need in order to live a normal life. Boating is not one of these things.
  15. BW. That's going back a bit From the close building it does look a bit like it could be Berkhamsted. Gas locks the bottom one ? I've not been through there since CRT took over but spent quite a bit of time around there mid 00s. Might be somewhere totally different.
