I think it is more because they are working with 'Virtual' AToNs. For example, by transmitting an appropriate signal on the AIS (Automatic Identification Syatem) 'system' they are able to replicate a 'virtual' lighthouse or navigation mark in the same way that a ship or other vessel is able to be represented on the AIS. Vessels within range pick up this signal on their transceivers and it then plots automatically on their electronic charts DGPS will still be needed by the vessels to plot their own position - the lighthouse authorities are simply keeping up with technology and, in so doing, ensure that their VAToNs are only received by those to whom they are directly rrelevant. I guess that in the long term there may be savings to be made, but the reality is that they are also having to maintain some of the physical AToNs to keep up with international committments etc.

Part of my marine work includes overlap with the NLB (Northern Lighthouse Board) and yes, the vast majority of their lights are directional. However, anyone who has spent a night outside in the vicinity of a lighthouse will know that the light can be visible behind the itended direction - don't know why, maybe due to reflection of particles in the atmosphere? The evolution of AToNs (Aids to Navigation) is rapid at present - Virtual and Electronic means such as signals transmitted on AIS are expanding, whereas only last year the lighthouse authorities discontinued their Differential GPS service. I am a total luddite, and have always enjoyed looking at charts and maps, so was somewhat disappointed to hear that the UKHO is to discontinue printing paper charts. Anyhoo, my original point was/is that it just struck me as rather ironic that the first Dark Light Sanctuary to be declared in Europe was on an island which has a lighthouse on it - nothing more than that!

I may be missing something here, but I see in the news that Bardsey Island (Ynys Enlli) has been awarded status as a dark sky sanctuary: Dark Skies: Welsh island is first sanctuary in Europe WWW.BBC.CO.UK Ynys Enlli, also known as Bardsey Island, officially has one of the best night skies in the world. Yet when I think of Bardsey I immediately think of the bloody great lighthouse that is stuck on the end of it: Bardsey Lighthouse | Trinity House WWW.TRINITYHOUSE.CO.UK

More likely handbags at dawn!

Was that prior to n APF show by any chance?

Try a kilt?

I very nearly replied something along the lines of 'anywhere between not very much and far too much' It will depend on many, many variables - access, amount of vegetation/trees, etc etc. Piccies would help others give you an idea. Welcome to the forum by the way!

WRT other ongoing threads: Can you not persuade her she needs Yew?!

So I have observed!

Sorry but: All I know is that you can't make pancakes without breaking eggs!

Is the outer tube cylindrical/round or oval? If the former could you not fabricate something out of standard section alloy tube if you have the drive shaft?

WTF is this all about?: Roald Dahl: Rishi Sunak joins criticism of changes to author's books WWW.BBC.CO.UK A debate rages over changes to references to characters' appearance and weight in the author's works. Wokeism gone (even more) mad. Why on earth does the BFG having a black coat need to be 'corrected' FFS?

Nope - just a case of reading the thread before posting. Simples....... (realise I may have missed the sarcasm but it is a working day after all!)

She actually advised that she is based in Hampshire

That is why I differentiated between firewod cutting and working in the garden. The 36v is great to have in the barrow for removing larger branches/small trees, but is not really up to serious firewood cutting (IMHO)

Or why not both? An MS 181 or 211 (or similar) for when cutting a load of firewood, but a Makita 36v for when working in the garden. They are great for picking up and removing a limb that is too big for the loppers etc, but run out of charge quite quickly when cutting anything bigger than 4" diameter. (I also wonder how good the high current draw is for the batteries as they seem to get quite warm sometimes)

It was a good distance downstream Mick, but I totally agree with your thinking. The only thing I can think is that there is a sizeable weir about 300m downstream of where she went missing - I have worked on the flow measurement site associated with this a number of times and have watched canoeists get stuck in the stopper which forms on the downstream side. I can only guess that her body may have been caught up in this, underwater, but would have thought that the search crews would have given this a thorough going over? Not sure if the river is tidal as far up as Rawcliffe Road - if so then maybe she was brought back upstream by the tide?

You know that thread which is currently running about air compressors.........?

The pronlem is worse though if you don't keep a full tank. Moisture in the air gap condenses out onto the sides of the tank and run into the diesel. The bacteria (ie the diesel bug) feed on the boundary layer between the water and diesel and, whilst it eventially starts off as resembling dark iron filings, quickly develops to form stringy, jelly like material which can block fuel lines and filters etc. The most common blockage point on our boats fuel tanks is the pickup pipe, but if it gets past that then the CAV filter usually pritects the engine. We ave suffered huge problems from the issue since the boats were able to return to work post Covid so now use fuel additives every fill which seems to have sorted out the problem. Whilst we had to remove and clean three tanks in 2021, all of the tanks (predominantly plastic) were fine throughout 2022.

Well spotted that man...
