If not feet it will be metres.

So less reliance on contractors . Yes that would be good But who would you give the job to if not C&RT?

Given the theoretical opportunity of placing the job of maintaining the canals elsewhere then what would you do?

I sometimes think we should get a fee at a couple of locks locally where there are usually some spectators.

Its not a mandatory check on motorhomes (as said) but guess evidence of annual checks is considered important when its time to sell.

So which are the handful of important rules you mentioned earlier ?

In the BSS requirements a great deal of emphasis is placed on fuel filler hoses (and breather hoses) . Clearly, from the extract below, there is no scope to relax or omit this particular check if the fuel hose connections are not visible. It does seem that past poor practices are being corrected by the BSS.

Let me rephrase it. Does anything in the BSS allow the age of the boat to be taken into consideration? If not then all boats must comply with BSS requirements which are in place at the time of the exam. So the complaint , if any , should be against every prior BSS examiner. BSS started around 1996 I believe ?

I think bss are quite right to check up on examiners as there have been some reports which suggest the examination of the relevant parts of the boat has been less than satisfactory or non existent. I suspect the checks have been actioned and those poor practices have been eliminated some time ago. Unlike a mot on a car a boat has to achieve the current standard regardless of its age. However it would be upsetting to have to alter arrangements which passed 4 years ago if it was an item where the bss requirements have not changed. You are suggesting a increased risk of a failure point on a boat that has passed before and with no changes to the boat. In the OP's case would it not be better to delay the bss until he can be available to deal with any issues that arise .

You can get tomato oil which is made from the seeds. But I don't expect it is used in the production of fuel. And it does not appear to be red.

Crown oil say this Renewable perhaps. Sustainable perhaps not.

Meanwhile diesel price is 10p less than 2 months ago.

Correct.

A short while back I have had Jabs for Flu, Covid and a Pneumonia so feeling fairly well protected. But aware Covid is around as it may never go away . I don't think there are any legal requirements to isolate but I hope most people will be responsible about isolation if they know they are infectious.

However the boat replenishes 15T of water back into the lock as it leaves the lock. Therefore saving 15Tonnes of water being transferred from the upper pound for the process compared to the lock empty case.

How is that a problem? That's how it is isn't it . The boat has to be afloat still with the water in the lock at the lower level. its just freehand diagrams , not to scale . Yes

Its not an error. The lock with the gates and paddles closed is effectively a specific cube , (or more accurately cuboid).

Only in your head

Yes it is

This balance is achieved only when the cycle is completed and the boat leaves the lock . Water from the canal then fills the hole in the water created by the boat. The boat does the job of moving its own weight in water out of the lock when it enters the lock. The boat does the job of moving its own weight in water from the canal into the lock as it leaves the lock. But the weight of water used in the operation of the lock is always reduced by the weight of the boat . .

Correct. The boat has displaced water. The weight of water displaced is equal to the weight of the boat. So you agree there is less water in the lock when the boat is in the lock? .
