    LED headlights.

    I thought tunnel lights were to show the tunnel wall not the way ahead. We are not doing a massive speed - why do you need to see so far ahead? I have 2 of these LED lights fitted both are turned 60 degrees outwards to the tunnel walls as well as 45 degrees up, The one at the stern with me is at 45 degrees up on the centre line. I have asked boaters coming towards me in the tunnels when we finally pass slowly and all have said no problem. If I do need to travel at night, although why is beyond me, it is a moment to adjust the angles.

    sound deadening

    Have had TW Marine fit both hospital silencer and sound deadening. The effect is sooooo good. The silencer is the bigest part of the effect. Where as many places have one or two silencers available these guys have a load which meant that the result is very neat. I have no links to them but I can recomend their services.

    More hot water?

    I use a hand operated stirup air pump and push the water out through the cold connection. The cylinder has domed ends at both ends so can not stand up

    More hot water?

    Thank you for the thoughts. The connections on the tank are all on the top-side of the tank - somewhat different from the SureCal ones. Should have included this information in the original post. The line up is Hot water out 22mm CH input 22mm CH outlet Immersion heater boss ( 1kw unit fitted) 15mm input from engine 15mm outlet from engine Pressure relief valve Cold water in. Regards Dave R

    More hot water?

    Good morning. On Legacy we have a twin coil calorifier, 55 ltr manufactured in about 2007. The second coil is not used & is blanked off as the central heating unit has been removed. I have fitted temperature sensors to the skin of the calorifier and, after a few hours cruising, get the results : top 60C mid level 40C and lowest level 30C. Not knowing the internal layout of the tank, I don't know if the two coils are at the same level. I believe in vertical calorifiers they are but have no knowledge of horizontal ones. I would like to generate more hot water and ask if it would be practical to connect the second coil (22mm) in line with the first coil (15mm) - with the usual adaptors. Questions : could the coils in a horizontal calorifier be at different vertical levels? I have been unable to find any diagrams of possible internal layout. Made more difficult by not knowing the manufacturer. Will the engine jacket water pump be powerful enough to push the water around a second coil? Calorifier is located under the bed with 3m of pipework to the engine. Thank you Dave R

    Fire extinguishers

    Now I thought that the fire extinguisher had to be pressure tested after 10 years. If & when that new pressure test has ben done then it becomes due every 5 yars. This is why extinguishers should be replaced every 10 years as it is not ecconomic to do this retesting.
  7. The erosion of the steel is known as "explosive pitting" caused as previously mentioned by the speed of the propeller and the proximity of the pipe steel. We used to see it a lot in the enclosed prepellers on ghe ships. I would not call bow thrusters on ships "cissy buttons" they help to control the vessel. I will agree that too many boaters mis-use them as they do not understand how to get the best from them. A lot of bank erosion is down to inexperinced boaters using them to push off the bow having unmoored. Just walk forward and give a good shove, however in the middle of the canal or river when manoeuvering that is not so easy. In the same disparaging vein I suppose hot water tanks could be classed as a bit cissy. Old sea dogs and canal boaters used to get bathed from a kettle of hot water off the stove. Some things just make life easier and better. Now that's going to be fun . . . .

    Have Diesel Cars Had Their Day ?

    For interest please read this article. Rather long and the real information is in the last quarter of the piece. Article on emissions testing.

    Beta 43 temp sender

    On mine it is on the aft starboard side of the engine alongside the cylinder head.

    Sourcing Lamp Oil

    B & Q have loads as it is the same as used in the garden "candles" that they sell. Major supermarkets also have stocks during the barbecue season.

    Legacy was docked earlier this year to check how the Keel Black was performing. At the waists there were extensive failures of the coating in round spots which resulted in a significant amount of corrosion. It is thought that the positive ion paint has been affected by the lower cathodic current at the distant point from the anodes. These areas of paint failure were pressure washed and standard blacking applied. The usual mechanical damage at the bow section from my careless lock entries were also cleaned and re-blacked. In the areas where there had been no failure the results are looking good but the increased costs of the Keel Black do not justify my using this product again.

    Out again

    Propeller efficiency decreases with speed. Propeller slip changes quite dramatically as the boat speed through the water increases. So engine revs are not in any way directly proportional. The readings I noted earlier, were done on the same stretch of canal but, as mentioned in subsequent posts, who knows what the depth of water was at each observation point. We have all heard the change in engine note when the boat reaches a part of the canal/river where the water depth is much greater - usually at the same time the boat speed increases. When allowed, in deep water, I have turned up the speed to the full 2200 rpm and achieved 5.5mph.

    Out again

    During the last voyage on Legacy, I set up the car sat-nav to see how engine revs changed the boat speed. Accepting that it may not be completely accurate at slow speed the numbers are, however, indicative of how the boat reacts to engine revs. I found that my usual running speed of 1500 rpm gave a speed of 3.5 mph Coming down to 1100 rpm gave a speed of 2.8 mph Tickover 900 rpm gave 2.1 mph I think that many boaters reduce their engine speed and do not realise how little that takes off their top speed. In addition many reduce the engine revs just as they approach moored boats and let the high momentum carry them on. Being able to increase the revs on the other side of the moored boat indicates to them that they have slowed down. Stands back and puts on flak jacket.

    Metric stupidity

    Ah the usual stuff, 2.44 meters of 2 x 1 for the cabin sides to hold up the 8 x 4 sheet of 19mm ply. I was working for British Steel in the early 70s when we went metric currency, thought everything was going to follow suit then but we just ended up with a right mish mash. Even the kids nowadays are part and part. Bring back the rod and chains - I say.
