What is called the plimsol line is just the foam from the lock from when it was under water not an old layer of muck. CRT stoppage notice yesterday said lots of fuel leaked into the lock so I presume that there has been some clea up including detergent.

Section 10.16 of the current licensing T&Cs. 10.16. You will not behave in a way that causes Our employees or representatives to fear violence or feel harassed or distressed. This includes verbal abuse or threats. It includes harassment, aggressive behaviour, or physical assault. If others on your Boat behave this way, we may take action against Your Licence.

My Webasto is controlled by a Heatmiser Neo, works well, no idea about the wiring difficulty as it was installed by the boat builder during build.

I have registered so I will see what is said and ask that question if possible. It will also be worth seeing what they have to say on lithium iron phosphate / lead acid hybrid. I keep thinking about the Nordkyn Design view The simplest safe lithium installation: leaving a sealed lead-acid battery in parallel with the lithium bank at all times allows disconnecting the lithium capacity in case of problem without any issues. The additional SLA doesn’t contribute to any meaningful capacity; its function is ensuring charging sources always see a battery in circuit. They do however note that changes are needed to the charging regime and adequate protection of the LFP is still required.

Might be an interesting webinar especially as it is coming from an insurance company. Description Are you wondering whether you should be making the switch to Lithium batteries onboard your boat? The technology behind Lithium batteries has come on leaps and bounds in recent years, and more and more people are seeing the benefits and making the switch to a hybrid solution or even a fully Lithium solution. But how do you do it safely, and what other factors do you need consider? With many differing opinions around, it can be hard to make an informed decision. And with the status quo being perfectly acceptable, why would anyone make the switch and potentially end up with a costly invoice to pay, a set of dead batteries on a freezing day, or even worse, a catastrophic fire? But don’t worry, we have brought together a panel of experts to help separate fact from fiction and provide trustworthy information in plain English. Link to Zoom webinar details and registration

To answer a couple of your questions. The calorifier has two pipes running inside it. The central heating water flows through one of these pipes so the central heating water is separate to the hot water and does not mix heat is transferred through the pipe. Hot water from your engine goes through the other pipe so when you run the engine you can also get hot water.

I am not sure that it matters a great deal in the context here as long as it is consistent because you are seeing if there is a 50% difference between the 2 cases, so charged up to 1% tail current or similar would suffice.

Who hit the rear of the rescue boat pulling up at the service block.

A question, if you take the 2 identical 100Ah batteries fully charged then discharge A at 5A for 10 hours and B at 50A for 1 hour. Leave them to settle and the fully recharge them. How many Ah do the 2 batteries take to fully recharge. Has this been measured. Peukert states that B will have less Ah to deliver, but is this because the Ah are consumed or that they become unavailable. I have some sympathy with Nick's point that the chemical energy is fixed, i.e. there is a fixed number of moles of lead to react and if they are not reacted then they should count towards the remaining SOC. However, I have my own experience as a Chemical Engineer designing large chemical reactors that at times if you makes things react faster, the progress of reaction is not necessarily uniform and the faster you go the more this is the case especially with solid/ liquid or solid/ gas reactions. Does this apply in this case, as you discharge the battery faster, the lead reacts to lead sulphate in a more chaotic manner and results in not all the lead being available for reaction, in some reactions the solid reactant becomes encapsulated in reaction product rendering it unavailable. It is still theoretically available for reaction but on a practical level it is not available. In the case of batteries, if this effect occurred then you should count is as reducing the available SOC because you could no longer call on this. Just musing on this, I may be way off in my thoughts but the question about recharging would be interesting to have an answer to.

A cable tie is good for clearing the drainage holes, they are reasonably stiff for poking through the holes, but flexible enough to bend because some drainage channels have little covers on the outside and will not damage the glass if it has dropped.

Our tiller is chrome, when the boat surfaces are very hot on a summer day the reflective tiller is cool. Therefore you need to mirror coat your roof to keep it cool.

No, you can only moor on the islands ( for want of a better description) outside the Holiday Inn, there are chains / floating barriers at the end of the islands preventing access to the basin.

Lymm Boat Sales 50ft lined sailaway with electrics £67,500 so £70,000 for a 4 year old boat is about par for current prices. Unless you have been buying new recently you have missed the big increase in prices, bare shell for £35k, basic sailways for £50k.

I am not sure that you can run an alternator direct into a B2B, there are many posts on the Victron Community of people trying this and failing as the alternator delivery current and voltage swing about as the dynamics of the B2B charger are faster than those of the alternator causing oscillation. The battery damps all this out by acting as a large capacitor. This is why Sterling do the Alternator to Battery charger which is more costly but has stuff in to mange the alternator current draw without having the battery in place.

Thet is one of those installations with the thruster tube under the rear of the well deck and only separated from the cabin by wooden lining. The type that if it leaks fills the cabin with water so one less risk having had it removed. They are also long and hard to black down the whole length. The pictures also show it was insulated. Looks like a good job.

If this is below the waterline I am not sure that the Vactan will completely cure / dry out due to the steel being cold from the low water temperature even if the air is warm. It may fully cure / dry out but it will take an extended time to do so and may well get overpainted before it has had time to cure. I think that relying on the Vactan here as a primer is not optimal.

That is an interesting note that got me thinking and I agree completely, putting it in different words. In winter you have the inside of the boat at 22degC, the outside air temperature is 0degC and the steel will need to be a few degC above zero to dissipate the heat by convection, say 3degC. The temperature difference that the foam is dealing with is 19degC and lets say the heat flow out of the boat is X kW. In the worst of summer, the outside air may be at 30degC, but the solar heating of the steel means that it is much hotter, a dark boat may be 60degC and the inside is 22degC, a difference of 38degC, twice the winter difference so the heat flow into the boat will be 2 time X kW. This is why light colours are preferred for boat cabins / roofs as the solar heating is less.

As I posted above, for a 3:1 gearbox I have a 20" x 15" which works well and is sort of where Vicprop comes out for a 58ft narrowboat, so if there is enough room to go up to a 20" then that is one option, haul out fee plus £600 for a new prop.

A broker usually sends out a form for the owner to fill in with all details about the boat. The broker does not necessarily confirm these. The terms and conditions state the boat is sold as seen and the broker is not responsible / liable for the information provided. They are not selling the boat in the strict legal sense, the seller is selling the boat, the broker is merely facilitating the sale by acting for the owner. If the owner misrepresents the boat then this may not come to light until the survey or after purchase. Some brokers may do some checks, some may not and may not care. If the owner information and the boat appearance are at odds the more reputable brokers may not take the sale on or have the owner correct the information, others may not care.

A bit late to this, but as a comparator for a properly set up system with a 3:1 gearbox that works well my boat details are 58ft narrowboat with 28" draft Beta 43 with a PRM 150 3:1 gearbox and a 20" x 15" propeller (Michigan Marine) Typical cruising speed 3 to 3.5mph at 1300-1400rpm Stops quickly, the boat builder described the set up as "gripping the water well". Confirms what has been said above that an 18" prop on a 3:1 gearbox is too small.

One issue from a lapsed BSS from CRT interactions may well occur if you try and book something through the CRT bookings web page such as a lock passage, visitor mooring or Anderton lift. We went onto the Montgomery last month and the booking system would not let me book because the insurance details had expired and I had not put the new policy details in. Whilst this is not the BSS per your question, I would expect consistent checking on the booking site.

David, In today's Boaters Update, CRT published the roll out for converting their pump outs from card to contactless. This is the first time that I have seen a list of all their pump outs, 70 of them, I assume the list is complete. You may find this interesting / useful. 48498-roll-out-of-contactless-payment-tech-at-boater-facilities-latest.pdf Peter.

I am moving to Tattenhall towards the end of the year, seems a good choice for the cost and they did have a few vacancies when we sorted this out in early September. Swanley Bridge and Overwater are nice but were full in early September with no vacancies on the horizon, Aqueduct may have some vacancies but 25-30% more expensive than the others in the area. Venetian Marine had vacancies and were competitive, some like the location, others do not like the open basin. They said they had dredged it as it was shallow as most people in the area know. The one downside of them is the electricity is not metered but included but if you have a leisure mooring you are not allowed to keep your boat permanently hooked up nor have heaters on board over the winter, which made it a no no for us. We did not try the ABC marina at Nantwich, seems OK but may not have much space either, it was pretty full in there last week when we visited the Cafe. Regarding the Shady Oak, I believe it shut after lockdown but is now open again under new management. We called in early September and had an excellent meal and some good beer.

You need to be aware that whilst many marinas do offer visitor mooring for a single night or a few nights a. they charge handsomely for this, often in the range of £20-£30 per night, one I know is £40 per night, so it is an expensive way to buy electricity and b. in the winter these are often taken by people who moor for the whole winter in the marina
