 Yes I was wondering if Athy might misunderstand and take your £40k figure as total build cost!

 

But LFP batteries have tumbled in price the last couple of years surely? 

 

 

I got some lithium for a fit out of a 4x4 off road camping trip just finished the trip in Australia. Good trip but for the mozy bite that gave me “ross river virus” just waiting for WHO to came up with a vaccine for it lol. I got 120 amp batteries hr for £1.80 per amp £216 I got two and ran it as one 240 amp hr. They also do 200 & 300 amp hr but they cost more like £2.63 per amp. 

Miss the boat life but out back camping comes close. Now back home in Goa (wife India born) monsoon rains like 2 meters in 6 weeks so alls good for us. 

regards to all on the cut

Goa is lovely, really nice people, could easily live there

But could 'not really nice people' live there as well ?

Yes for sure there are some real arse hol** living here. One in our building my wife took the wife to cop shop that shut her up. Wife is European to look at but a real Hindi speaking fire brand when she gets her steam up to max pressure lol. Over all good place to live been here 11 years now but for the 3 years over covid on so called lock down on our boat now sadly gone to a new owner.

Well at least @peterboat used an Oxford comma to make his intentions clear.

Indeed -- but (like this post) the first phrase should probably have been followed by a semicolon or dashes, not a comma... 😉

Only 2 commas used so they fit the bill, we arnt in America you know.

You need to read up on your English grammar, methinks... 😉

Moored last night behind a boat who's engine kept starting up ,run for 30 minutes or so ,then stop . Turned out to be a hybrid electric with a diesel generator which started when the batteries needed a top up . What a nightmare boat with the weather this year they are getting little solar so burn diesel every day. Planet saver ......lol

One badly set up series hybrid isn’t a reason to say they’re all bad. The generator should be running for longer to charge the batteries more to avoid short cycling. 
 

Series hybrids aren’t designed to get all of their propulsion power from solar; that’s impossible given the size of a narrowboat roof. The generator will kick in to assist, and in a well set up system the engine will be running at a far higher efficiency than an engine used for propulsion only; it’ll be driving a much higher load, which is good for diesel engines. 

 

Best not to comment negatively on things you don’t know about - just ask for advice on here!

The question that should be asked is which is burning most diesel the hybrid or the fully diesel.

 

IMO if a hybrid anything is burning less fuel than its counterpart then it is an improvement no matter how slight.

In this case I wonder if the boat has been equipped with all the electrical equipment people have on land because of the large battery bank and generator, and the battery cells are starting to sort, so a high domestic load causes the generator to cut in and out. In that case I expect the generator would be running when moving as well, so it might burn more diesel than a conventional boat with less fancy electrical equipment and owners who were truly energy conscious.

Actual measurements (see Ortomarine trial, and borne out by my experience) is that properly designed hybrids typically use around half the fuel of a diesel, but as usual it depends on usage -- can be less in summer (or zero) depending on cruising hours, or more in winter or with long cruising days (maybe a third saving).

 

A hybrid whose generator/engine is starting and running every 30 minutes is set up wrongly. With the recent rubbish weather my generator was used most days when cruising (but not every day), usually run for a couple of hours when travelling or locking or moored when it wouldn't bother other boats -- and certainly never after 6pm or before 10am... 🙂

That's bad design or setup. My generator doesn't start even if we're doing cooking (electric hob/oven) and a wash/dry at the same time, and the kettle or toaster is also turned on.

 

Domestic energy use even for this is small compared to electric propulsion, a full wash/dry cycle uses less than 3kWh (about an hour's cruising), as does cooking a full dinner (hob and oven).

 

Yes that sounds a lot -- especially peak power use with everything on, up to 6kW or so -- by the standards of a conventional diesel/gas boat, but the *energy* use is much less than propulsion -- and heating when it's cold.

Some hybrids will now be getting on for 6 or more years of age and many of the early serial ones plumped for lead acid batteries and I recall one company using the Fischer Panda 48VDC generator which could not get the voltage high enough for a full charge, let alone an equalisation and being told that you would fully charge them when on landline, i.e. it was not a good set up for long trips off grid. Such boats will now have knackered lead acid batteries well down on capacity running an all electric boat being propped up by the generator.

And maybe that's what happened with the boat @Annie cariad posted about.

 

That's not a problem with hybrids as such, any more than a clattery old diesel pumping out clouds of smelly blue smoke while charging slowly for hours is a problem with diesels as such... 😉

Like IanD I have a serial hybrid, unlike Ian's mine isnt automatic, I have 5 kw of solar so mostly manage ok, winter time I start the generator when needed but mostly whilst moving to stop moorers being disturbed. Ian's generator I suspect will be virtually silent as it is possibly the best series hybrid money can buy

Though it can start/stop automatically, I now tend to choose when to run the generator to suit the circumstances. You can hear it when stood next to the exhaust but it's pretty much inaudible from a boat moored next to us, the dual silencer and extra soundproofing made quite a big improvement compared to the normal setup.

 

Thanks to the inertia frame it's also much better than normal for the oft-ignored route of annoying other boaters which is generator noise/vibration through the hull being transmitted through the water and being audible in other boats -- when moored up the other day the engine of the boat moored behind us (battery charging) was noisier inside my boat than the generator... 😞
