  7. I don't consider I lose space by having an engine room, there is so much crap in there its hard to find the engine, where else would I store it all?

  10. As kids we used to clip a playing card to the bike frame using a clothes peg so it hit the spokes as we rode around making a delightfully unholy racket. Maybe bikes on towpaths should do this too then at least we would know they were there!

  15. Thanks everyone for all the replies and advice. I'm glad to say that my Dad has got his camera back yesterday - a big thank you to Colin from Shardlow, who handed it in to the Wychaven Council offices at Pershore. It's re-affirms my belief that the vast majority of boaters are lovely people!

  21. The extra few % added to the licence is a drop in the ocean compared to the purchase price of a 'fatty' and I would suggest that even doubling the licence fee will have little effect on the numbers of fat-boats. Generally (bound to get shot down) fat-boats are shorter than NBs so the licence is a fair bit lower than an equivalent area NB. The licence for my 36' x 14' foot (504 square feet) is £686 (Although it is actually only £411 as I stay on the rivers, few canals are fit for 14' wide boats) The licence for a 67' x 7' foot (469 square feet) is £1020 I would not be worried if they introduced a 'square footage' charge such that irrespective of dimensions a boat with X square feet paid the same as any other boat with X square feet. That would appear to be fair. The other way of looking at it is 'mooring space taken', where 36 foot boat takes half the length of mooring pontoon than a 72 boat does - should they therefore pay only half the fee ? Should it be made compulsory for NBs to breast-up ? Following the phased introduction of the fat-boat surcharge (in 2023) I will be paying an additional 20% above a NB licence cost, which (at current rates for comparison) means I would be paying : 36' x 14' = £823 64' x 7' = £1010 With similar square footage to an 'long' narrowboat I am still paying considerably less. I really do not understand what the problem is that folks are having - "short and fat is cheaper than long & thin".

  22. Getting the balance between do-ers and desk jockeys is always a challenge, and the sentiment that we should sack the lot and leave it all to people on the bank is great as a rallying call. It is also not going to actually work! To make things work, you actually need the guy on the ground who sees the ideal solution, without regard to cost, and the guy in the office who sees the cheapest solution. Then they need to TALK to find out why the cheapest solution isn't going to work, and why the ideal solution is unaffordable to find a solution that loses as little as possible from the ideal, whilst keeping the cost down.

  25. For the sake of less knowledgeable members reading this thread. Often on such resistors an R takes the place of a decimal point and R means in effect "Ohms" so 47R = 47 ohms. 4R7 would mean 4.7 ohms.

  29. The ceramic blocks are wire wound resistors probably about 5 watts. To get the alternator to power up when it starts it uses the warning light, but if the bulb is too low powered it won’t work. Solution is to either use a brighter bulb or increase the current by putting a resistor in parallel. The resistance value is not critical, and in your case a 47ohm resistor has been used. 47ohms at 12v is just over 3 Watts, so the resistor needs to be a bit chunky. You can get them on eBay, look for ‘5w 47r’ Added Jen beat me, I’m getting slow at typing

  31. One of the terms and conditions you accept when you get a licence states you may not run an engine (other than for travelling) between the hours of 8pm and 8am. So it is pretty cut and dried. Someone will be along to quote the actual term/condition shortly no doubt!

  36. Thank you! The panel is now in and so far, working OK. Don't have a photo yet of it installed. For anyone interested in doing something similar, here are some of the design decisions and circuits used. As has been mentioned before in this thread, boats are electrically very noisy environments. Pumps, motors, relays, alternators, radios are all putting noise and voltage spikes in to the supposedly DC wiring. Delicate low voltage, low current electronics needs protecting against this if weird results, or device destruction is to be avoided. I stole some ideas from the early Bedazzled LED's I have on my boat and also from the Megasquirt project, which is an open source vehicle engine management system. These products have been designed for boat and the similar automotive environment. There is a 22V metal oxide varistor on the 12V input into the 12V to 5V DC-DC convertor. This safely dumps any high voltage spikes, either negative or positive to earth. Protecting the 5V Arduino there is a 5V transient voltage suppressor on the output from the DC-DC convertor. There is another on the resistor voltage divider in to one of the analogue inputs used to measure boat voltage. There are capacitors on the digital and analogue input lines to filter out any high frequency signals induced in to the lines. Most resistors are standard 5% tolerance carbon film. The ones used for voltage divider resistor networks are 1% tolerance metal film type. I've attached pictures of various input circuits below. Also below is the sketch for the Arduino Leonardo for anyone who is interested. Feel free to copy and modify to suit. All this stuff will almost certainly need altering to suit the senders on your boats engine. Jen /*A digital instrument set for boat Delta Lady. Written by Jen-in-Wellies, June-July 2018.

  37. Boat is 9 years old, the original paint will likely have faded and lost some of its shine, degree of fade will depend upon colours and frequency of maintenance (polishing etc). Even if you get the exact same paint it won't match so don't worry too much. I find a hint of matting additive can help the new to blend in with the old, but many people think boats look better as they age a bit anyway, the quest for a perfectly shiny boat without any scratches is folly. A pristine boat with a single obvious scratch looks very sad whilst a beaten up old working boat always looks good. ................Dave

  39. Gloucester (Gloucester and Sharpness) to Weedon (Grand Union) VIDEO - https://youtu.be/JJqEwwDcoyg Some artistic licence was taken over the tunnel scenes (they do not appear in correct geographical or time sequence). This video was shared by my nephew to a site called Reddit. I was really surprised by the reaction from, what I assume is a largely American audience, first because the comments on Reddit were so civil and upbeat about an old English couple piddling about on a boat and secondly because they were so unaware of the existence or nature of our canal system. I regret, I didn’t have time to answer their various questions at the time.

  41. One of C&RTs KPIs is the number of closures due to things within their control : № of days of unplanned closures to navigation within our control (individual instances over 48 hours) 458 (10 months 2017-18) 400 (Target 2017-18) 441 (Actual 2016-17) If they started to tell the real reason behind all of these 'boater damage' & 'vandalism' incidents they would be so far off their targets the DEFRA grant could be at risk.

  42. It is annoying and I really resent CRT’s new strategy of blaming every infrastructure failure on “vandalism” or “boat damage” when in reality it is because, eg, the lock gates are completely rotten and/or the infrastructure lacks any preventative maintenance. They lie too easily.

  47. I stopped flushing engines 40 years ago, with modern oils there is so much detergent that they are spotless inside provided they have been serviced regularly. Flushing old crudded up engines does more harm than good, leave the gunge where it is, stirring it up is asking for problems. Always ensure that engines are run at the proper temperature, cool running is bad.
