This is generally correct. The CO2 breathed out by humans is not counted in carbon calculations So things you do physically with hand tools can be the closest thing to carbon neutral and could be carbon negative eg planting a a tree or growing vegetables. HVO , if made from vegetable bi products like the unwanted stalks of vegetable plants or from spent cooking oil, would be a great fuel. But I believe a lot of energy is required to make it so it can never be carbon neutral. The cutting down of rain forest to grow palms for HVO production is clearly not sustainable but this is my main worry against HVO as the fuel retailers cannot be certain of the source of the fuel on a world market. Rain forests cannot be reinstated. They are the lungs of the earth. If we remove them will will die. The suppliers must prove there is no rain forest destruction involved but I am not sure this is possible. But really HVO if it could be proven to be truly sustainably sourced is a perfect replacement for diesel and instantly reduces emissions and thought to be not prone to bug.

Its sustainable if they plant new trees to replace the removed tress. The trees were planted in the first place for paper pulp but books and newspapers are much less used these days so there is reduced demand. Therefore the use of the same fast growing trees for fuel instead of paper pulp isn't such a bad idea. Transporting the wood pellets from Canada to the UK however does seem bonkers

Narrowboats are designed and built specifically for the UK canals. Only the very adventurous take them to sea and then only in benign conditions. 2metre waves will almost certainly sink a narrowboat. A lumpy water boat may be able to do some canals but likely to be uncomfortable and possibly unwelcome and certainly not able to do narrow canals. One boat to do both jobs is not possible.

We just bought an air fryer and tried it the first time yesterday evening at home. Hopefully it will not join my wife's collection of unused kitchen gadgets. From a boating perspective we would be using the air fryer when hooked up to shore power which we have at our home mooring and at some locations we visit on our travels on salty water. Similarly we have an electric kettle on the boat for use with shore power.

Yes. See earlier post from Jupiter1124 . Really I do think HVO is potentially an ideal boat fuel but not acceptable if it involves cutting down rainforest to grow palm oil. Cut out the rain forest destruction and use otherwise waste vegetable matter to make HVO and that would be great. Equally hauling wood from Canada to fire a power station in the UK is not carbon neutral. Better than burning coal but not carbon neutral.

I did not say that . I would be very much in favour of HVO if it is responsibly sourced. But I am not convinced that it is . My objection is to the inaccurate use of the term 'carbon neutral' HVO certainly is low emission so better than diesel . But that doesn't make it carbon neutral.

Energy is required to produce HVO and to deliver the fuel. No fuel is carbon neutral unless it involves no fossil fuel and it is produced and delivered to its point of use by a non industrial process.

non-combustible or incombustible might be better terms

HVO is not carbon neutral. HVO emissions from an engine are certainly less than Diesel. HVO at present requires rain forest destruction to grow palm for oil.

The manufacturer takes sole responsibility for declaring conformity with the standards. This applies to all products that are CE or UKCA marked.

Round turn and two half hitches

I may be wrong thought it was said elsewhere that closing canals was not legally permitted?

Well that did quite well with BWML which they then appeared to give away . Getting rid of the profitable bit seems like a deliberately destructive act.

People who feel they should pay more and wish to pay more to C&RT are free to do so since C&RT are a charity and they accept donations. I don't think license fees should have any connection with the age of the boat although I believe some very old boats are already licensed at a favourable rate . An old boat has the same navigational requirement as a new boat of the same size. My boat is 20 years old. Does that count as ''old''? As for means testing of the boater that's a non starter since C&RT are not in a position to ask questions about income and savings.

I wonder whether the above pictured pontoon at Dunham survived the winter floods.

They have raised fees for all Some more than others

Its not for the boater to spot whether other boats are licensed or not. C&RT say they don't want boaters to act as spotters as they have rangers who perform that task.

Really the first step would be to draw off more water to see if the problem persists.
