  5. The dutch barge version was with the shaft hanging off the side of the Boat with engine at the front. A bit like a longtail but instead of sticking out the back it was over the side. Odd arrangement presumably for Boats not going through locks and a predecessor to the Opduwer pusher tugs.
  6. This is the sort of Boat which should be temporarily floated then towed to a suitable location where it will not be an obstruction then sunk and pinned in place and allowed to return to nature. Its part of the history if canals. No harm will be done and very little energy will be consumed. It will remain visible and gradually be overtaken by reeds and such like. Consuming energy to break up something which has no scrap value is a worthless task. History should be retained and be available to view even if it is a reed bed.

  9. What is the height difference between existing gearbox output and the tail shaft? It seems to me if there is 'plenty of room' you could consider using a cardan shaft custom made to your requirements. Weld up a bracket and put a plummer block on near the end of the tailshaft to protect the stern tube.
  10. Was that one of the BoA Boats? I know that Mr Ward had the old bantock cut and shut job plus some driftwood but there was another geyser a rasta who was on an old wooden motor which still looked vaguely useable except there was no motor any more. Is it that one ? Also someone has had the Z iron away.
  11. Is there something which the previous examiner passed which you think the next one might fail?

  13. It seems a little poorly written. Dispersal sale? I think it was a disposal sale. And what is the 'British Water Board' ? eta At the forward end is the gas locker is sited.
  14. I sometimes wonder if permanent magnet alternators may be an interesting solution for this. Not looked into it as I do not use rotating electrics for electrical power production unless the Boat is moving. I have a suspicion in the back of my mind that a PMA and lithium batteries may prove to be good bed fellows if done right. It would want to be done right. If you install a pma and the Boat catches fire causing you to break your legs as you rapidly exit the vessel without advanced planning don't come running to me to complain.
  15. No idea what the rating is but side loads with heavy power use go straight to the pulley so this part needs to be well sorted. Beta marine had problems with pulleys and big alternators at one time. I wonder if it might be worth putting two alternators on opposite each other.
  16. When it was a generator it would have been on a direct drive not a side loading belt drive. belt drives can be a problem unless a lay shaft is used. This has been suggested and is a good approach but quite complex to execute.
  17. Maybe don't use the engine as a charging set. When I had a RN DM2 it used to put a little bit in via the alternator when Boating and if I was stopped for a few days I just ran a small Honda genny for charging. It depends on your usage pattern but I tend to think when people start asking questions about alternators they might be using the engine when stationary to charge batteries which in my opinion is not appropriate. Leece Neville large frame alternators are quite popular for this. Buses, large marine engines, trucks etc.
  18. Yarwoods presumably. The back end has done it no favours !! Also a little too shocking to weld a hoop on top of the stem for a fender. Some people !
  19. Fire is interesting. Bulkhead mounted is a good approach but I wonder if there is some artistic licence in that image. Looks a bit like a Jotul but they are much too big and also mounted on legs. Intriguing if it is an actual fire. Do any still exist?
  20. We had 4 lavatories, two kitchens, servants quarters upstairs, gardeners cottage and land. 5 sitting rooms and 7 bedrooms. According to Country (sp) Life magazine it was "one of the lesser country houses of today". Thems were hard times I tell ye. Orchards and swimming pool, and tennis court. We was poor but we was honest isn't it a bloomin shame. Its the rich what gets the credit and the poor what gets the blame.
  21. I ran a DM2 on a 55ft trad narrow boat for 12 yars. Most of this was cruising around the system. It was a nice unit I would not moan about it. A bit noisy but mine was in an unusual engine room which did not have a cabin behind it. I suppose having a luxury Boat with one of these contraptions at the age of 21 and free from encumbrances was a little unusual and could lead to different experiences. If I was doing it again I'd just put a jap kubota in there with similar torque and sensible propeller. . The RN makes a nice sound in theory but can be a nuisance. It depends what you do with the Boat. I did excessively large number of hours which tends to make the noise seem worse. I can still hear the galloping horse and visualise the following up crankshaft. Nice units and of course very traditional but I would rather a DM3 myself. There will be questions about whether it is an Altricham unit or an Essex made unit or god forbid a Vero Engineering version made in Southampton. I had an Essex unit and felt very good about it. PRM 160 the God of marine gearboxes.
  22. In about 1996 I split a seam on the polyprop tank on my narrow boat. Cookham lock. They used to have Chubb fire hoses on reels for the supply. Great idea. High volume. I was having a cup of tea with the lock keeper in the house and completely forgot about the water situation. Nobody else about as it was early spring. So the discharge from the hose was more than the gap around it and the vent combined. Result was quite a lot of water in the wrong places. Someone else I spoke to had broken a stainless steel tank at the same supply point. Water supply systems have since been altered on the River. It was cool to be able to load water fast but one needed to be on the ball. I miss the fire hoses in a way. It was a great way to reduce the potential for queueueing at water supply points. Ironically back in those days there were far fewer Boats with large water tanks so the problem which was presumably trying to be solved did not exist.
  23. My decade long residence on Limehouse Cut is coming to an end in April. Too much building work its now just an urban canyon I need out. Someone else can occupy the goldfish bowl mooring. As there is no lock separating the cut with the Lee it seems to be a canalised part of the river. When there was a lock I suppose it was more canal like.
  24. I put a Rayburn MF in my narrow Boat in 2005 and it went straight in through the front doors in one piece. No problems. Normal sized doors not wide. It is a nice thing to have and I plumbed in a 28mm primary flow circuit from the boiler then tapped in radiators and a hot water tank. All worked lovely. A LOT of fuel and ash going in and out of the Boat. I don't think I would do it again although it was pleasant to he fair. When I sold that Boat the buyer broke it up on site and scrapped it. Worth checking the boiler is a small side only type rather than a saddle. It might be difficult to use the heat from a saddle boiler on a narrow. The older Royal type Rayburns seem to be slightly smaller. Mine was an MF which is the same as a 216.
  25. Presumably one would need to take into account the bore and length of the hose. I wonder if using black builders buckets (or any other buckets not specifically marketed at a defined racial group) might be quicker on a fast tap. Fill one, transfer to the road cone funnel into water tank while filling next bucket &c. Also good exercise. A bucket with a high rate bilge pump in it is another obvious way of getting around hose bore issues.
