  1. That's some diesel usage!!! Whilst I'm sure there was no speeding involved, I would imagine a lot of cruising was done at close to the speed limits? with the consequent penalty in fuel usage. I estimated that the above journey would have cost me about 55 litres with some limited heater usage. I worked it out as follows, The Bure to Wroxham bridge is 26 miles x 2 = 52 The Yare and Wensum to the yacht station is 27 miles x 2 = 54 The Thurne to Potter bridge is 3 miles x 2 = 6 The Chet is 3.5 miles long x 2 = 7 I guessed at Fleet Dyke and a cruise around the inner Broad = 10 miles The detour into Ranworth and back 3 miles The detour into Rockland staithe = 4 miles For a total of 136 miles. At this time of year my boat would do about 2.5 miles to the litre with limited heater running, so 135 divided by 2.5 is 54.4 miles. At my last fill up in September I'd done 183.5 miles since the previous fill up, which hadn't been brimmed to the top, and got 72 litres in giving 2.55 miles to the litre. It would have been a shade better if the tank had of been completely full on the previous fill up. I normally work on 2.6 - 2.7 for Summer running. Winter running is more like 1.9 - 2.1 due to heater usage.
  2. I wonder if some of this could be linked to recent events last year which are still being investigated by MAIB? I've seen a lot of posts on Facebook this year asking about handover and do you have to have the formal handover even if you've hired many times before. The answer has always been that this year hire yards are insisting on a proper handover even if you have hired before. Richardsons have even made a point about this in the press recently. The point is that if every hirer is having a full handover then surely unless there has been an increase of staff on turnaround days, then something has to suffer somewhere. Are less engineering hours being spent on pre departure engineering tasks with perhaps more of those tasks being left for weeks when the boat isn't on hire, or the Winter maintenance period, in favour of spending more time with the hirers on handover? I don't know why, but I feel I need to say this is not a criticism of the hire industry, but plainly labour only goes so far and can only be completing so many tasks at any one time. Is handover maintenance suffering as a result of more time spent with hirers at handover?

  5. 3,4-Methylenedioxymethamphetamine It's far easier to say MDMA, or more commonly known as ecstasy. I wouldn't be advertising having them delivered though
  6. Depends on whether they're able to leave! It could be The River Garden tonight and The Town House tomorrow. I wonder if there are any hangovers this morning?
  7. If you tiss the mide have just a tother rund
  8. I believe the downriver end is 1 or 2 inches higher or better clearance than the other end. Looks like the two previous high tides were above prediction as well as the previous low tide.
  9. Chalk Hill Brewery. The pubs actually called The Coach and Horses. Well worth a visit.
  10. There are worse places to be stuck than Thorpe, plus you could always walk up the road to CHB a pub well worth a visit. There's also plenty of busses that go along that road into Norwich itself.
  11. But that is not strictly true. A resistive load will cause heat at the point of resistance for instance a light bulb is a resistive load and glows from the heat produced at the point of resistance i.e. the lightbulb. As Griff has already acknowledged the problem wasn't using a fuse, it was using the incorrect fuse rating for the circuit it was protecting. I'm not trying to be pedantic, but fuses are inherently safe if used correctly. Trips are generally more expensive and convenient because they can be reset. If Griff had used a trip rather than a fuse, then the inconvenience of keep resetting the trip would have led him to replace the trip for an uprated one of the correct rating for the new pump. However simply replacing the fuse for one of the correct rating would also have removed the fire hazard. To expand further on what I'm trying to say, it makes no difference if you use a 10A fuse or a 10A trip, if you have a bad connection in for instance a spade terminal onto a pump that is providing resistance and therefore getting hot when you try and draw more than 4 to 6 amps, then the terminal will get hot, and possibly present a fire hazard, and neither the trip or fuse will blow. It is equally imperative that all aspects of your electrical system are properly installed, maintained and regularly checked, especially in such a hostile environment as a marine one.
  12. The current terms of hire on the Richardsons website actually has three types of deposit! 1. The good old fashioned Damage Waiver Scheme. It does say there will be an additional fuel deposit as well to pay. The waiver is non returnable. 2. Fuel and Security Deposit Scheme where you will loose some or all of your deposit based upon any damage caused, but limited to the cost of the deposit which is £300. Slightly confusing because it says if you cause damage in excess of £300 you will not be asked to pay anymore, but you will be charged for any fuel used. So although you have paid a fuel deposit, effectively if you cause damage there may be nothing in the pot to actually pay for fuel used and you may still receive the bill for fuel. 3. Additional Deposit Group and Party Booking All male, female or young crews will be asked for a security deposit of £50pp on arrival at the boatyard. Presumably declaring yourself as binary or gender neutral should exempt you from that one?
  13. I assume by voltage trip you mean the resettable circuit breakers? These do not sense voltage but like fuses are rated to trip once a certain current is exceeded, unlike fuses they can be reset. The main difference is that the way in which they operate to break the circuit does not generate much if any heat. A trip is wired in series with the circuit which means it has no concept of voltage. To measure voltage or to sense a voltage drop or gain you need a neutral or earth to read the potential difference against. Therefore if a trip only has two wires, one in and one out it is only measuring current. The main difference apart from the fact that a trip is resettable and a fuse blows and then needs to be replaced is their method of operation. A fuse is basically just a thin piece of wire sized to melt when too much current flows through it. Fuses will allow slightly more current through than their rating for a period of time and they will gradually get hotter which in turn increase their resistance leading to the eventual failure or blowing of the fuse. However the heat in the meantime can be a problem as demonstrated in the pictures above. Fuses really work at their best when a sudden short circuit occurs and they blow immediately. They are not so good when running consistently at slightly above their rating. Correct sizing of the fuse is important here. On the other hand a trip generally works in one of two ways. Either a bimetallic strip that will bend as it gets warm and eventually will bend and break or trip the circuit. The actual contacts are rated far higher than the trip and therefore do not get hot and the bimetallic strip will bend at relatively low rises in temperature, certainly before it gets anywhere near hot enough to do the sort of damage you see above. The other method is a small electromagnet which is sized that once enough current is being drawn through the device the magnet becomes strong enough to pull the contact open and thus break the circuit. Again the whole process is relatively heat free.
  14. I would say that was a close shave there. Two lessons to be learnt there. 1. Always keep at least a couple of spares of each rating of fuse. It is so tempting when a fuse blows and you don't have the correct size replacement to put in a slightly higher or lower rated one. Things work and you remind yourself that you will purchase the correct size and replace it at the next opportunity and then a few months pass and it is still in situ and not properly protecting the circuit. 2. When ever replacing a component of the circuit such as a new pump, or light etc. Always treat it as a complete new installation. Check the power requirements of the new part. Check whether the current wiring is still sufficient. Check whether the fuse needs to be downrated or uprated to cope.
  15. To be fair I do my best to keep it clean and apart from the dipstick the only other thing stored in there is a spare temporary mooring rope which is used as an extra spring in some mooring situations. The gas locker has a couple of aluminium braces near the top which keep the two gas bottles in situ and the dipstick and rope just sit across the top of those so they are handy to get too and kept out of the water.
