  1. It is possible to inadvertently set up a continuous payment direct debit or credit card arrangement with scam companies. You order a free sample of something on-line using a card, and you do not notice that by doing so you have agreed to the (very one-sided) T&C's (which most folk don't bother to read). In fact you have agreed to receive monthly supplies of the goods at a price to be determined by the supplier, and the nature of the agreement is that you cannot cancel the contract - only the vendor can do that, and only after you have contacted them by phone on a specified date related to the repeat supply date. When you receive the sample of the (rubbish) goods you decide not to buy any more. Then when you receive another (tiny) consignment of the goods a month later you check (if you are wise) your card statement and are amazed that you have spent a small fortune on stuff sent from an unidentified vendor in Singapore (in SWMBO's case). In her case the bank (M&S) started a co-operating banks' procedure where they could cancel the arrangement and request a refund - the cancellation took place but not the refund. According to Money Saving Expert, The Financial Conduct Authority says: You have the right to cancel them directly with your bank or card issuer by telling it you have stopped permission for the payments. Your bank or card issuer must then stop them – it has no right to insist that you agree this first with the company taking the payments. However it appears that this does not apply to the purchase of goods or services. Be warned.
  2. yeah, I couldn't agree more. Boris and Co. should be blocking the rivers with their fat bloated bodies, saving the poor folk who bought riverside homes or those who bought homes built on floodplains from getting wet. Don't get me wrong, I have great sympathy for the flood victims, but 'flood prevention' is not the solution; flood avoidance is.
  3. well he must either be easily satisfied or just plain disgruntled, cos there has been no definitive answer to his query. Bearing in mind that narrowboat hulls can be divided into 3 parts, 2 of which have more or less fixed lengths for any conventional boat, and block coefficients considerably less than 1, and for the other part Bc is close to 1 but of varying length, it is hard to see how he has drawn any meaningful conclusions from the discussion.
  4. strange that OP asks a specific question which appears rather irrelevant regarding UK canals and narrowboats, but fails to answer the question - WHY ? if we knew the circumstances he might get slightly more constructive answers,
  5. wot they said. it isn't worth the bother. There are proper boats (i.e. designed for the conditions) to hire on Lough Erne and on the Shannon/Erne waterway. Why take (unsuitable and possibly dangerous) 'coals to Newcastle' ?
  6. your location of 'Amburg' appears to be in Virginia, USA. Do you have any knowledge of the UK canals and the boats that use them?
  7. perhaps it's a scam. prob'ly cloudfare is a spoof website. the missus had 6 phone calls from HMRC yesterday telling her that she MUST call an 0844 number immediately to discuss an important matter..... I 'spect it's just a way of generating income from a premium phone line.
  8. of course you could fit hydrofoils, then you could use them to vary the angle of toe-in dangle as well as reducing the water disturbance ........ just remember to check the headroom at low bridges.
  9. just up the road from here is a place called Pitch and Pay Lane. During the Plague the inhabitants of Brigstowe (as it was then) went to a boundary wall where folk from the neighbouring villages would throw food over in exchange for coins thrown back.
  10. I would still ask ..... Y ? There are several factors affecting the way a narrowboat 'swims' including for example the shape of the bow and the plan view of the taper of the lower hull forward of the propeller. The block coefficient is the least of your worries. If the bow and stern are well shaped to reduce wave-making then the block coefficient will be whatever it turns out to be, but you wouldn't base your design on an 'ideal' block coefficient value. Having said all that, on a typical canal in the UK the wave-making is more the result of displacing water in a narrow channel than the fine tuning of the hull shape. The boat never approaches the 'hull speed' which is way more than the speed limits on UK inland waterways. On the other hand, if you want to design a narrowboat with an efficient (and potentially faster) hull form for use on wide deep rivers then you would do better to copy an 'inspection launch' hull form, which is primarily designed to swim smoothly and at higher speeds than a traditional narrowboat that was designed only to carry freight. An inspection launch was intended to carry senior management in comfort and has much finer bow and stern shapes and will have a much lower block coefficient.
  11. More years ago than I care to remember (1977 actually) I was employed by WHO under an aid programme to Malta to improve the sewage outfall arrangements. The raw sewage from the Capital Area had been piped to a location 2 miles south east of the Grand Harbour where it discharged at high tide level over the rocks and straight into the sea. Unfortunately the prevailing current was towards the north west taking the diluted sewage back up the coast, past the Grand Harbour and onwards past the resorts of Sliema, St Julian's, St Paul's Bay and beyond. The project involved laying an outfall on the sea bed to discharge the sewage at a depth of 45metres (chosen because this was the depth limit for conventional diving) and 500m from shore. There was no suggestion that the sewage needed to be macerated, let alone treated, although it did pass through an Archimedes screw pump that helped to break it up. It was assumed that by the time the stuff rose to the surface it would be sufficiently diluted. Since then I believe the arrangements have been upgraded to meet EU standards. The down side is that during the diving operations I got a chronic ear infection that left me with substantial hearing loss in one ear. It is shocking that the UK has not eliminated the risks more than 40 years down the line. Perhaps we are only concerned about meeting beach quality standards, and ignore river water quality.
