  1. It happens in bigger locks too, ship canal locks included, affecting any vessel in the lock in just the same way regardless of size and displacement. Someone with a good grasp of Fluid Dynamics needed here I think. Edit to add : -- Looks as though that someone turned up while I was typing this
  2. change name to Tony Dunkley

  3. I really don't see how derogatory remarks about the way she makes custard or porridge are relevant to any of this.
  4. Yes, it certainly is, and in it's common usage it is a practical and useful way of comparing or assessing towing capabilities.
  5. If that's so, I hope I never have to stand under anything she's been in charge of constructing.
  6. I can fully understand why you say that . . . most of what I've said has clearly gone straight over the top of your head. As far as the old adage goes , . . . that really is good advice, and I think you should take it.
  7. The only sort of fittings I've mentioned in connection with NC's boat are the cleats she's so worried about . . . so, no, I'm not being obtuse.
  8. Good idea . . . when you've nothing worthwhile to say, keeping quiet is the best option.
  9. Why? I think foredecks and gunwhales are fairly common features on boats . . . aren't they?
  10. Not if a bridle was rigged to share the load between two cleats . . . . as in Post 21.
  11. The maximum bollard pull in tons, your boat could ever produce, is at best, your engine horsepower divided by 100. So you would need 250 bhp plus to pull out or bust even one of your precious cleats.
  12. The "load on the pull" as you call it is limited by the power of whatever is doing the pulling . . . the weight (displacement, if it's a boat) of whatever is being pulled makes no difference at all.
  13. Maybe they should put the address of the local Undertakers on there as well.
  14. Ignore it at your peril . . . Mary Queen of Scots did. Edit: . . . just noticed, I was beaten to it. . . I wonder if the present owners really intended it to be taken seriously The Executioner's Risk Assessments would have made interesting reading.
  15. That's right . . . the BP efficiency with a small diameter, high RPM propellor on a motorised soapdish like Naughty Cal's would be considerably less.
  16. So would I . . . a well established "rule of thumb" for small conventional tugs with open propellors is around one ton of BP for every 100 Horsepower.
  17. Approaching a grounded boat bow on may well be the best plan for passing the towline, wind and stream permitting, but pulling from forard using astern power won't give you the best chance of success. No conventionally propelled vessel will develop as much bollard pull running astern as when running in ahead. Use two lines the same length from one stern cleat with an eye at both ends and long enough to run forard outboard of all the deck stanchions etc., then have the grounded boat pass their line to you and make it off to both the eyes at the forard ends of those lines . . . now move steadily astern and as the line(s) begin to take up you will be swung stern on to the tow . . . allow the lines to go slack and quickly transfer one line to the cleat on the other side, then steadily ahead to take up the tow. You're now well out of the shallow water with the bridle that you've just set up giving you better steering and control than if pulling from just one cleat on one side of your stern . . . there's also the added bonus of dividing the strain between two cleats.
  18. I'm curious to know . . . what is a "tube" in this context?
  19. You consider that has not been done? Getting some facts right before diving in and posting the ill informed tripe would have been rather more constructive too. Enough said I think . . . shall we move on to something more constructive?
  20. The material used in what may look like some sort of Absorbent Boom can absorb water (and sink) if the "booms" are really intended for dry land use to retain or hold back spills running down such as gullies or to divert spills from drains or watercourses. It may be that the correct gear was not available at that time, and they were using whatever was to hand, on the 'anything may better than nothing' principle
  21. The S.G. of diesel (gas oil) is around 0.83 .... that's why it floats on water .... the quantity of any substance doesn't make any difference as to whether it floats or not. Are you now saying it was a "diesel boom" that sank rather than a boat.
  22. You're right about that John, I have taken exception to some of the posts on here, but I think anyone wanting to indulge in airing ill informed and unhelpful views and opinions, based on incorrect assumptions and preconceptions, really shouldn't start whingeing when they get a reaction they don't like. It does seem that there are still some who believe that in publicising C&RT's action against me, I was seeking help and support for myself, and I also recall being labelled as a "troll", a "piss taker" and indulging in scaremongering. Well, if anyone wants to continue thinking that, they are free to do so, but I would welcome them doing it quietly amongst themselves, as that may be of considerably more help in achieving what was my intention from the start, to make as many boaters as possible aware of how C&RT are prepared to treat them, and more importantly, the fact that due to C&RT's tendency to disregard, and operate outside of the Law, it need not be assumed that they will always succeed. Personally, I haven't been at all stressed by what C&RT have been doing for the past few months, I think a few people may have noticed that I am quite fond of an argument, but I am really concerned that now C&RT's attempt to make an example of me in order to help them impose CC'ing rules on boats with home moorings looks likely to fail, they will now turn their attention to others who may be more suitable for their purposes.
