  1. How would you know if abstraction is without permission? Near the bottom of the Stourbridge canal there is a large pump in a field, busily extracting water. I would assume it has a licence but have no idea?

    Lengthways trim

    We have the same problem with our Jonathon Wilson hull. I have adjusted the trim with additional ballast but its not been enough to resolve the problem. When we have a repaint I will be looking to revise the roof drainage. I had thought that this was an issue just with our boat, I find it surprising and interesting that its a common problem.

    My third SmartGauge...

    I wonder if what you say is really representative of how a SmartGauge works. These units do not measure anything but the battery voltage. They they cannot infer SoC from just the voltage at a point in time as you would also need to measure the battery temperature. The algorithm must therefore calculate SoC from the changes in voltage over time. Consequently,a fixed error will not matter, its much the same as operating the battery at a different temperature. Now if the error is varying over time than that would indeed make a difference. Perhaps one day the algorithm will be published and then we will know how it works?

    Vacuflush Dometic Leak

    This will not help on the cassette version as the liquid would not pass through the pump. The pump is simple enough to take apart and clean. The valves are simple rubber flaps so turning them over helps if they are worn

    Vacuflush Dometic Leak

    There are several places that the vacuum can leak, mainly on the O ring seals. For a start look at the large seals on the spout that enters the cassette (Clean and grease them , this may help). There is also the small spout where the air is pumped from the cassette. After that it could be the pump as the valves in the pump have to prevent back flow. I have also had a fracture in the pipe that is on the suction side of the pump. Vacuflush toilets are easy to repair and you can get spare seals cheaply by purchasing O rings from Ebay etc rather than from Dometic or their agents. If you search on here there are several posts on repairs, try searching for this as an example Vacuflush toilet repairs By jonesthenuke, September 8, 2016 in Boat Building & Maintenance Having sorted ours out last year the vacuum lasts for many hours (overnight?) Edited to add:- Just to be clear, you have changed the seals on the toilet, does the water level stay in the bowl?

    Who know if they had a former. Sometimes its not needed.

    Big Twin Cylinder Diesel

    It sounds quite quiet on no load. I reckon it would have a good bark when fully loaded!

    Webasto or Espacher

    I will have to try listening to a current model Hurricane then. Ours is now 10 years old and has had very little use partly because its so noisy.

    Minworth embankment repair

    I take your point, but the implication is that this was a conscious decision. However if it had been a conscious decision and they were attempting to deliver an operable canal ready for Easter, they could have re-opened with a restricted depth, communicated this clearly to the canal users AND issued a plan to have another stoppage to recover the situation. In the event they reopened the canal with the work apparently complete, no plan for recovery and then the subsequent stoppage appears to have improved but not fixed the problem properly.

    Minworth embankment repair

    I am less than impressed with CRTs response. Instead of properly assessing of the depth was adequate they seem to have crossed their fingers and hoped nobody would notice. As nicknorman says, its very simple to assess the level. I hope CRT have learnt something, not least that they should check and not rush.

    Webasto or Espacher

    We have a Hurricane. It is in a cupboard in the back cabin and is too noisey. Seriously considering a webasto.

    Minworth embankment repair

    I suspect that the more time passes since the event, the more the explanation will be massaged into something more acceptable. It was an error, I hope they will do better in the future and I certainly hope they will plan a stoppage to correct the current problems properly.

    Bow thruster tube replacement

    If you have a limited area of corrosion and 2.5 mm was thickness remaining then I suggest you should not panic. Its quite unlikely to perforate for quite some time with that wall thickness and even if it does it will initially leak rather than catastrophically fail (so inspect it routinely). This gives you time to consider options and plan remedial work. Over the years I have been involved in many instances of pipework where wall thickness has degraded from the original. There are options other than tube replacement. One approach that is commonly used in industry is to clean the external wall of the tube and wrap in an engineered composite (similar to fibreglass). The wrap provides a leak tight pressure boundary with equivalent strength to the original tube. Done properly this will withstand vey high pressures (and temperatures) many orders of magnitude greater than required for a bow thruster tube. Whilst I am not suggesting you contact these people (the cost would not be insignificant) the following people would do a good job and you will see that they can do this tube of repair on 12" diameter lines and up to 250Barg. http://icr-world.com/products-and-services/technowrap-engineered-composite-solutions/piping-systems My advice would be to get the tube inspected properly. Ensure its got 2.5 mm wall thickness (ask whoever does the thickness checks for the minimum thickness and the tolerance on the measurements). If this value is correct get the tube cleaned inside and out and properly recoated to prevent further corrosion and to resist internal erosion. If the corrosion is worse, e.g thinner and or more extension, then it is time to consider blanking off or tube replacement. Oh, and ignore the comments about sissy buttons etc. You can decide for yourself if you want to keep and or use the bow thruster. (I will now head for the bunker......)

    New Waitrose almost on the Oxford

    Maybe but it is one of the few places that stock Black Bomber cheese from Snowdonia and that's a good enough reason for me to go there occasionally
