A step.in the right direction or too little too late?
IIRC Labour suggested this some years ago, when sewage polluting rivers first came became public knowledge and the current government poo poo'd it (pun intentional).

I remember that, when I was taking driving lessons in the late 1960's, the instructor said that "three-point turn" was a misnomer, as the requirement was just to turn the vehicle round using forward and reverse gears. I took my test in Cardiff, where the camber of some side roads was so great that the crown of the road was higher than the pavement. On those roads, doing a 3 point turn used to involve doing a hill start as well.
I took my driving test in Surbiton, Surrey. Some of the avenues there are quite wide, and my examiner chose one of these for me to "turn the car around using forward and reverse gears".
I turned going forwards, reversed back across the road perfectly, then a lady chose to park exactly where I was turning, prevent me from completing the move.
I didn't know what to do, but my examiner got out and remonstrated with the lady, and got her to move along the road a bit and park there.
By now I was completely flustered and couldn't release the pawl button on the handbrake. When I finally managed it I shot across the road and had to reverse back again as I didn't have time to turn properly, turning an easy 3 point turn into a 5 point turn. I was convinced that I had failed and was very pleasantly surprised when the examiner announced that I had passed.

An "H" chimney on top of the flue should reduce the downdraft which causes the stove to belch fumes into the boat.

In the late 1950's, a cousin had a pen pal who lived in South Africa. Her father worked in a uranium mine, and she once sent my cousin, through the post, a matchbox full of lumps of uranium ore. They were crystalline and a dirty yellow colour, resembling irregular granulated sugar lumps. We often used to play with them when we visited.
I'll bet your mum didn't have any trouble finding out where you were hiding on a dark night...

No need. Two lumps will last all winter. Its exceedingly good.
Yes but just how big are these lumps?

When did you last buy diesel?
Winter diesel has a anti waxing agent added to prevent the formation of wax at low temperatures. If It starts and runs OK when the temperature rises, it will be because you have summer diesel in your tank which has waxed because of the low temperature and caused a blockage.

One thing which others may be able to confirm or otherwise.
Many years ago I had a mate who ran a grasstrack bike and sidecar. I seem to recall this ran on Ethanol or a derivative and occasionally caught fire. The problem was the fuel burnt with a clear flame so the first warning we had was when things started getting hot. The bizarre sight then ensued of us frantically beating out an invisible fire.
Might be something to consider if Ethanol is used as a fuel.
I remember watching a saloon car race at Goodwood many years ago. A car fuelled with ethanol crashed and caught fire. The driver, Peter Proctor, got out and began rolling about on the grass. It was only when the grass began to burn with visible flames that the marshalls used their fire extinguishers on him.

We did ours at Chesterfield with the local Electrical supply company with real switches
We had real switches and switchboards too, it was just that they were switching 50 volts DC. The only fake thing was the standby generator, which was a cassette player playing a recording of a diesel.generator... 🤣
Once you had passed the initial course you were then trained on specific real installations and if successful given either an 'HV Approved Person' or 'HV Competent Person' ticket, which was valid on that specific installation for one year
Later I became the 'Engineer HV' for a site and eventually 'Senior Engineer HV' for an area. These roles were mainly administrative, writing or approving method statements and switching schedules.

So it should, thats how you stay alive
Yes when I did my initial HV course at a BT training college the instructor wasted no time in saying not to worry, the switches were actually switching 50volts DC not 11,000 volts AC.
I told him he had ruined it for me as I wouldn't concentrate as hard on what I was doing.

This seems to minimise the danger from 240V AC. Not many milliamps in the right place will kill and so can 240V @ 16 amps. I think it is safer to not use "only 16 amps", because almost any current can be fatal.
Which is why domestic RCD's are set to 30mA (thirty thousandths of an amp for the benefit of those who don't understand the term "milli"). Even 30MA directly across the heart can kill in the right circumstances.
4 hours ago, Tony Brooks said:Tell me about it. When I trained REME apprentice mechanics, we used to get the electronics apprentices who had failed the electronics training so were sent to us being absolutely petrified of auto-electrical systems when they learned that at 12/24 volts we actually use and measure whole amps. It often took a fair time for them to grasp that at 12/24V the current that can penetrate most skin is not enough to hurt you. (Bit different if you happen to bridge a relay coil connections with your finger as it de-energizes, that can give you a surprise, but no danger).
I initially studied electronics at college, so was familiar with currents in the milliamp range. When I joined BT's predecessor Post Office Telephones, they put me on the power section, where I was put to work maintaining DC power systems rated in thousands of amps. Scared the living daylights out of me at first. Then they merged the AC & DC sides and I had to learn to work on 11,000 volt high voltage AC systems, which initially scared me even more!

Is this a pre-NAA marina?
You would have to moor there for a long time to break even on licensing costs, even with the proposed above inflation increases...

I've seen a GRP boat burn down to the waterline. Everything flammable gone above that level.
Aluminium boats can do similar. I remember seeing a burned out Sea Otter burnt almost to the waterline at Braunston a few years ago.

Just a thought. Considering the trouble C&RT were having with the M62 floating walkway I wonder have they decided they won't be moving it again? In which case the new dimensions are correct.
Perhaps they can consider installing something similar for the A45 Bridge just north of Braunston?

This was admittedly at least five years ago so things may now be different.
I'm amazed that you're still waiting patiently after 5 years .. 😂😅🤣

Yeah absolutely, i'm so used to this setup of manually switching that I'm honestly not worried about forgetting. Basically just can't get down into the bilge to rewire my generator until the weekend and i've uninstalled my old inverter already haha.
Like so?
That Is how mine is wired, even though the generator (Travelpower) was never installed.

London Building Acts - not London Building Regulations. In the good old days, building control in London was prescribed by primary legislation. And enforcement/approval was via the District Surveyor employed by the Greater London Council not the local authority although some parts of the LBAs did survive the abololition of the GLC.
Not sure it helps much in deciding how best to close a hole in a bulkhead.
Certainly in 2013 when I last worked on a London Data Centre, the London Borough of Tower Hamlets employed a Building Control Officer, who attended the construction periodically to ensure standards were being met and signed off the complete works before it could be handed over to the client.
-
When I worked as a project manager fitting out data centres, we used intumescent sealant to seal small holes. This was approved for use in building under section 20 of the London Building Regulations, for which sites has to be signed off by the Local Authority Buildings Approval Officer.

I remember seeing footage on a TV news programme a few years ago of a village in a narrow valley, I think in the West Country, where a heavy flash flood had ripped through it, entering some houses well above windowcill height, and leaving parked cars unusable. The programme showed footage, filmed by a resident while the road was still partially flooded, of a parking warden ticketting the previously-submerged and therefore undrivable, cars.
Back in January 2010 I was working at a data centre in Slough.
We contractors had to park in a council run car park as the data centre didn't want us using their parking facilities.
One day it snowed hard overnight. I arrived at the car park and parked where I thought my usual slot was
Later in the day a hoard of (well three 😂) traffic wardens arrived, scraped the snow around the parked cars, and ticketed those not parked between the lines! Fortunately I was within the lines.
It was a completely pointless exercise, because someone took photos of the snow covered car park, gave copies to those who were ticketed and they all won their appeals for incorrect parking.

When I was about 10 years old I went to my friend's to play with his Scalextric set.
Unbeknown to me his mum had sprayed a wasp with insect killer just before I arrived.
As I plonked myself on the floor next to one of the controllers, I felt a burning pain in my right hand. I looked down to see a wasp stuck to my knuckle, with it's sting embedded in me, writhing away.
I pulled it out and my friends Mum applied vinegar to the site. However my hand began to swell until after a short while my fingers looked like fat sausages.
I was carted off to the local hospital where they gave me a tetanus injection and put my arm in a sling to raise my hand to shoulder level.
Apparently the wasp continued stinging me as it was in its death throes and because circulation on the hand is fairly low, the poison didn't dissipate, hence the swelling.
I've hated the buggers ever since and usually strike first when I see one.

Next thing is to check the regulation.
You need to increase the load in steps, to near full power, checking and adjusting the output voltage and frequency at each step. A fan heater is a good tool because they usually have various heat settings. Best thing I'd to just run through, measuring, and then decide what output power you want to set it up at, with some idea then where it will be at no load and full load.
You may expect to find that at full output the voltage is at the low end of the range and at low output it is in the high end of the range. The official UK ac power supply limits are something like 236 to 254 V. AC
The regulated speed of the Beta will depend on how it has been set up. I would certainly expect more than 49 Hz to be available at no/low load. The speed regulation will inevitably have some droop, so if you can't get 50+ Hz at no load you will be looking at ~45 Hz or less at full load.
N
The voltage limits for the mains in the UK is +10% (253 volts) and -6% (216.2) following the harmonisation of our original 240 volts supply with Europe's original 220 volt supply to a nominal 230 volts.
