You mean like councils using the RIPA legislation for covert surveillance of terrorists to spy on the parents of school children 10 years or so ago.

But the CO is mixed with the other products of combustion which are mainly nitrogen and water vapour and unburnt oxygen so the lower density of the CO being measured in part per million has no impact at all, the CO can not rise all on its own. The advice is where you are protecting in the cabin against CO being produced by a stove or cooker where the burnt gas will be warm, then mount them high as the warmer burnt gas is lighter. However, where you are using them to protect against ingress of CO from an engine or heater exhaust from outside passing though door vents etc. then the detector should be mounted at the height you breath at because the burnt gases will be cooler by time they get into the cabin and they will have pretty much the same density as air. If you have a CO detector in the bedroom, then it should be placed about gunnel height is this is the level of your pillow.

Having been involved in competitive archery years ago arrows were aluminium, but a very hard stiff brittle aluminium, I do not know what alloy was used, probably a carefully guarded secret. If you missed the target and hit a brick wall the arrow did not bend but shattered with crystalline fracture faces. Taught me that not all aluminium alloys behave like aluminium.

We had one of the red handle isolators on the inverter and when my son was borrowing the boat his girlfriend tried her hair drier (I had no idea she had taken one), the load heated the isolator and the contacts opened losing power to the inverter. First and last time a hair drier was used on the boat.

My experience from around 35 years ago on my father in law's 45ft Springer on the Trent below Cranfleet cut heading towards Nottingham, perhaps 1 mile downstream of Cranfleet lock, summer time and low flow on the river. The engine blew a cooling water hose and overheated so we had to stop the engine pretty quickly. We could not moor to the bank so we turned into the current and dropped the mud weight, I can not recall if it was a bucket of concrete or a 56lb (25 kg) weight. Luckily it was enough to hold the boat against the limited current. We taped up the hose the best we could, connected the water filling hose to the kitchen tap, ran with the radiator cap off and kept a supply of fresh water into it to make up for the leaky hose so we could limp back to Cranfleet. My wife has not liked the Trent since.

The quoted 2,074 units over 26 days is a continuous draw of 3.3kW for the entire time, surely that should indicate to the marina that something is amiss with the reading.

You have to have at least one setting configured to allow remote overide of the shore power current limit. See Multiplus set up example. There may be other settings to allow the remote to switch between operating modes but without reading the manual I am not sure. Victron keep manuals on line.

Diggle flight at the western end of Standedge tunnel single top and bottom gates, ground paddles to fill and empty the locks, paddles on the same side as the lock beams. Much less walking around to do these locks. They are also relatively deep, sure they are around 10ft each.

They may have a stock for refills, but will not let people have a bottle if they are not returning an empty. Once I had my empties off ebay I had no problem getting a refill but nobody would let me have a bottle without an empty even if they had plenty in stock.

With COVID a lot of people were at home last year and the good weather resulted in lots of sales of patio gas heaters and BBQs, us caravan and motor home sales increasing, but I think it is the garden stuff that has used up all the spare stock. It may have relaxed a bit over winter but with a dry April, it has become a problem again. It will improve I hope as I would expect Calor to be having new cylinders made, but I do not know at what rate. With overseas holidays probably being restricted, I see the demand remaining high for garden use throughout 2021. If Calor are reluctant to buy lots of new bottles because they think it is temporary, then it may take longer to return to normal. The only way of knowing is if you have inside knowledge about the rate of new cylinder manufacture and demand for them.

I sympathise with you on this. We have just had our boat signwritten and spent ages going over fonts and decorative scrolls. I really like the lettering, perhaps not traditional but very flowing and should look good on a boat not trying to mimic historical precedent. A simplified rose could look good, perhaps with the petals painted black and not overlapping the text. I wonder if your signwriter could offer some suggestions for the rose. In the end, go for your gut instinct, this is one thing that is very personal to peoples perception and you could get diametrically opposing views.

When the new agreement was noted in the Boaters Update in late March (Bridgewater notification in Boaters Update) they stated 10 days on Bridgewater waters for CRT licensed boat, no return within 28. I wrote to CRT stating that This meant that for people transiting through from e.g. northern T&M to Liverpool and then back to home moorings on northern T&M needed to buy a Bridgewater license for the return journey. I have just received an email from CRT stating that the boat licensing team have clarified the times within the agreement to being essentially 7 + 3 days not one block of 10, the 7 days allowing for an outgoing passing from CRT waters to CRT waters passing through the Bridgewater and the 3 days for the return journey if this is within the 28 day window. The CRT booking system has outbound and return journey options when you make your booking. You do not need to book the return date when you make the outbound booking so can book the return based on what happens time wise during your journey. This makes much more sense and is more workable not needing a short term Bridgewater license for the return journey. They said they will be adding some more detailed instructions / explanatory document shortly to the booking page.

Do you have power consumers taking some of the 15 Amps so in actuality the charging current is lower, which is why the voltage will not rise. The other thought is that 15 Amps at 14 Volt is 210W, we are not yet into peak solar season, so that may be all you will get at the moment. Check your connectors and panels in case not all panels are supplying properly in you have several in parallel. If you have several in series, then if one is not working and they have bypass diodes then you can still get reduced power. Btw, I had the same issue with my Tracer locking onto low voltage point rather than ramping up the panel voltage and a quick off/on using the isolator between the panels and controller got it sorted.

Was it a particularly cold morning as the alternator regulator may well have increased the voltage to compensate for the low temperature.

Excellent, thanks for the suggestion, just found an empty 15kg butane cylinder 10 miles away on ebay so I now have a pair and am all sorted. Thanks for the info and suggestions.

Slim, Thanks for this, looked on Calor website and yes if I can get an empty butane 15kg I can take a 13kg propane refill in its place. On my old boat I once had a propane cylinder that was obviously a blue one that had been resprayed.

After a hugely protracted build delayed by COVID working, lockdowns, shortage of parts, our boat is ready to launch next week. Hooray. Then we get informed that the Marina has been told by Calor that they can only sell refills and customers must bring in empties, there are to be no new fill supplies, so we need to see if we can find some propane. It is the same everywhere we tried, retailers will not supply new fills, only replacement fills. Tried our local Calor depot, spoke to someone, they told me to email them with my requirements and they would see what they can do, zilch response. There is now a reason why you need to spend that extra £30k on a gas free, lithium battery based, solar panel bedecked, electric boat with a big built in genny. Anyway, I have managed to obtain a second hand cylinder to get me into the Calor game in time for the launch, but it has been an extra bit of hassle that could have been done without.

The stoppage notice is out for Stanthorne, CRT stoppage notice Unfortunately, we need to close the navigation at Lock 2, Stanthorne Lock on the Middlewich Branch of the Shropshire Union Canal to carry out a repair to the offside tail gate. We have seen further deterioration of the damaged gate and the feedback from customers is that the lock is proving extremely difficult to operate. Our engineers and operations team have been to site to reassess the lock and have deemed it crucial for the repair works to take place as soon as possible. To allow some movement of boats we will be starting preparation work on site tomorrow to allow the repair works to commence on Monday 19 April and anticipate these works will take 7 to 10 days to complete. Navigation will remain open until Monday 19 April and will be closed from 08:00. We understand how frustrating and disruptive this is for our customers so soon after restrictions on navigation have been lifted and with the number of other stoppages in the region. Our teams will be working 7 days a week to get this fixed and back open and we will endeavour to improve on this timescale. A further update will be provided by Friday 23 April.

If you go on the surecal website it gives recommended size for an expansion vessel, from memory 55l litre calorifier is at the upper limit for a 5l EV and lower limit for 8litre EV so you are looking for something in the range of 10-15% of the calorifier volume. The EV needs to be bigger than the water expansion as the air behind the diaphragm will compress.

Have a read of this thread on the basics of battery charging. Battery charging primer Your regime for cruising where you struggle after a few weeks is a sign that you are under charging your batteries and this is the main reason for killing batteries, if you operate like this continuously your batteries will not last very long. They need to get a good recharge at least once per week.

Yes, different pressures, the accumulator on the pump has a set pressures at the pump start pressure so this fills and empties over the pump operating pressure range. The EV on the calorifier is set to the pump stop pressure or very slightly above so it does not fill during the pump operating cycle, it only starts to fill once the calorifier is heated and the water expands. The pressure still increases when the water heats up but much less than without the EV.

Ceramic bowl Thetford C263 worked well for us, but only got 2 years experience before ee sold the boat, so can not comment on longevity.

I had a boat with a Barrus Shire 40hp from 2002 which was a 2000cc engine. I bought it in 2006 and sold it last year. It was a good engine, always ran well, started well, serviced annually and never required any major work on it. The only issue was the 70Amp alternator did not have a large enough engine pulley so only produced 45Amp, we got a bigger engine pulley and larger alternator, there are several people selling upgrades for these older Shire engines. The one thing to beware of is they can smoke a bit at idle which clears under load, I think this is to do with the injection design, so check this rather than immediately thinking the engine is worn if you see it at tickover.
