When no plug socket is available you could plug the electric chainsaw into a small suitcase generator. Then you get all the advantages of the electric chainsaw (quiet and fume free), plus all the advantages of a two stroke chainsaw (noise and fumes). What's not to like? ?

And pebbles, loads and loads of pebbles ?

My advice, based on practical knowledge of installing and operating Stirling emgines would be not to use a Stirling engine. When you try to scale them up from "toys" driving ecofans they are inefficient and unreliable. Before retirement I worked for a company in the UK which purchased 8 Stirling engines and associated plant from from a Danish company called SDK (Stirling Denmark) to fit into two ajor UK supermarkets. The engines were heated by burning syngas produced by burning locally sourced wood chip. Each engine was rated at 35ke (electrical) and 140kWh (thermal). Four engines were to produce all the electrical, heating and refrigeration (through fridges and freezers usimg heat as a source of cooling i.e. absorbtion and adsorbtion chillers) needs for a large supermarket. The plan was for my company to provide the "energy centre" free of charge, and operate and maintain the equipment to supply all electrical and heating needs at a fixed price (except for wage and woodchip increases) for a 15 year contract. The "redundancy" (electrical and heating when the Stirling plant was running at sub optimal output or not at all was to fall back to their mains gas and electricty supplies, which the company I worked for would subsidise by paying the difference between what we would charge for the Stirling generated energy and what the actual mains gas and electricity bills were. ? Had the Stirling engines proved successful, every supermarket in the chain would have had an "energy centre". Long story short, the unreliability of the Stirling engines, resulting in numerous warranty claims coupled with their need for frequent scheduled rebuilds (every 8000 hours to replace piston seals) bankrupted SDK, cutting off our source of Stirling engines, gasifiers and specialised maintenance. To get out of having to pay the supermarkets energy bills for the next 14 years, the divison of the company I worked had no option but to place itself into voluntary liquidation. The attached URL shows the presentation SDK gave to potential customers. http://docplayer.net/26885216-Stirling-dk-introduction-march-2012.html

You have to buy the Watermate keys. See CRT's licensing FAQ's. https://canalrivertrust.org.uk/enjoy-the-waterways/boating/buy-your-boat-licence/licensing-faqs

So did anyone born after about 1965 ? Is that so no one can see what they are up to? ?

Wishing you a speedy recovery Dave.

I have used Aldi Caravan Cleaner to successfully remove green algae from my cream sanded roof. Wet & Forget should also work, although to date I have only used it successfully on the fabric of the cratch cover.

Does stretching count as major work? (I would have thought so). If the boat currently has an RCD then it will probably need its stability retesting after the strecth. See previous discussion here.

My Lifeline AGM's can be equalised at 15.73 volts at 15°C. As you say, it is best to read the manual for any particular battery to determine charge voltage.

Why are you getting up in the middle of the night to turn the Wi-Fi off? Or do you only sleep for 4 hours a night? ?

Whilst the rested voltage of 12.6 volts indicates a fully charged battery, the charging voltage of 14.27 with a 14.4 volts charging source indicates that it isn't. This is because the plates on brand new batteries are not "fully formed", that is not all of the active material (lead oxide) in the negative plates has been fully cured yet. This is normal and your batteries are not yet at full capacity. Battery manufacturers do not supply "fully formed" batteries because to do so would reduce their cyclic life and also cost them more to manufacture. Don't worry, your battery will gain capacity over the next few charge/discharge cycles, as the active material continues to cure and as it does the batteries will accept less current (tail current) when fully charged.

According to the BBC article "In an emergency it can be controlled by humans offshore using satellite and internet communications." Obviously this will rely on the remaining passengers alerting the humans offshore. ?

Buddy spillchucker grr ?

What is the continuous output rating of the genny and what load was it feeding? It could be overloaded and is trying to protect itself.

True, my omission.

Presumably it's also available in white? ?
