  9. Abingdon, near the bridge, are cheap as well. Any split.

  18. https://www.apolloduck.com/feature.phtml?id=514944 There is also evidence of a stove being in situ at some time. The sad thing about this boat is that almost everything movable has been stripped out. To my eyes it could become a nice little boat with time and money! Also depends upon a survey! The fact it is so sparce could be used for bargaining.

  19. Starting from the observation and working back to an explanation: it is certainly my experience that there are circumstances in which increased power leads to decreased speed. But I have not conducted a thorough analysis so . . . I think part of the issue is not to assume that the whole of the forward speed is obtained simply by thrust through the prop shaft onto the boat itself (like it might be with a jet stream) The propellor is pulling water from in front of the boat and forcing it out behind. Part of what this does is to create a 'slope' so that the boat is 'falling' down in a forward direction. If the demand from the prop is increased and the physical context cannot meet that demand then gradually the boat comes closer to the bottom and ground effects take over. Ultimately, and one has seen people, not always novices, doing just this - they end up with the boat 'attached' to the bottom and the more the power is increased the more the boat is pulled to the bottom and stays there. The wave effect no longer propels the boat forward and all of the energy is dissipated into, in effect, churning up the mud. Another context is to watch closely what happens when passing through a narrow bridge hole. If the power level is kept constant then it can be easily seen that the forward speed drops noticeably. Overall, any 'proper' analysis needs to recognise that the changes in power (which usually result in greater thrust but, of course, there is the possibility of causing bearing to begin to seize so that less of the power goes into thrust) alters the overall behaviour pattern so that linear formulae do not necessarily work. One other item to throw into the ring: on a sea shore, waves break because of the differential ground effect: the top part of the wave continues at its deep(er) water speed whilst the bottom part is slowed down - ground effect - which allows the top part to overtake and hence create the breaking wave. All of which probably proves that my involvement in hydrodynamics of hull forms is very ancient indeed and that I have forgotten almost all of it! Instead, I simply prefer to treat the canals with a degree of respect and seek to find the way in which they work for me rather than against me. Makes for a simpler life, especially as one's own physical capabilities reduce! (Note: I keep putting more and more into it but life inexorably insists on slowing down . . . )

  20. £4.50 is excellent price for an engine

  22. problem arises 'coz inland boaters don't expect waves, so don't buy proper boaty stoves. I blame those peeps who want to cruise, rather than remaining moored up all the time, if nobody moved their boat then the problem would never arise. Of course, proper boat stoves have fiddles to stop pots sliding about, but it would be sacrilege to suggest such an in no vashun for canal moorers.

  23. Cast-iron is virtually non-stick. Heat it gently and it's great for frying eggs. You can get them with ridges for 'grilling' steaks. Or even with round recesses to stop yer eggs going all over the place.

  24. But increasing engine power will never slow you down although you reach a point where the increase is very small.

  27. I wrote 0.13p, not £0.13 (nor £0.13p). So 186 litres would be 24p. The prices are the same throughout the Thames Water region.
