I never went to SA but spent time in Malawi, Zambia and a little bit in Kenya and Zim

I did business in Zim and Namibia and used to drive into Zim quite obtain about 1200 kn JHB to Harare doing busness in Beit Bridge the main boarder between SA and Zim

I did Computer systems for SA and Zim Customer clearing Bills of Entry's so would visit to new customers and support existing customers

We aren't doing so bad. Many of us have hybrid boats i.e. wind plus fossil power. Hybrid power for cars seems to be working well at the moment .

Hold on a minute. Toyota claim a potential range of 750 miles on one charge and a recharge in 10 minutes. At how many amps? I'll let someone else do the sums, but I bet it's a helluva lot more than my household supply can deliver without blacking out the neighbours.

I doubt that 10 minutes is 0%-100%...probably a oft used metric like 20%-80%....don’t forget Toyota has already been done for false advertising

1. You would only need about 500w of panels... Only... I sail an older 36' boat and it has not been easy to find enough free room to put up 180w of solar panels.

2. A small generator... why not? Buying an additional engine which can not be used to propel your boat to charge another engine so that engine can propel your boat... In what world does that even begin to make sense?
1. I can see that 500w might be tricky. We fit 280w on the main hull of our 30ft tri comfortably though. 2 of them are stuck down to the deck, 1 fixed when needed to the top of the sprayhood. That one's dedicated to charging our electric tender outboard. Being a tri, we could get another 200w on each outrigger, meaning self sufficient electric power is viable for us.
2. Diesel electric trains do that generator thing, as does ’Victoria of Wight’, the wightlink ferry, and many, many other ships, trains etc. It’s very efficient. Generator and engine are matched, the engine is always run at it’s most efficient rpm.

Very, very few ICE vehicles could manage that either.

My current car will achieve 600+ MILES, the previous one 750+ miles ( I've gone petrol to save the environment!) I can refill to full range within 5 mins.

Now to green travel, flappy things! I too use the ICE as little as possible, entering leaving harbours / rivers and manouvering. I am now at the point of needing to refill (1/4 full) it will take approx 150 litres. The last time I filled the boat was August 2021, it has motored 180 miles due to 'no wind' and provided heating over 2 winters.

Is it environmentally friendly to scrap a perfectly good engine with 1500 hours use for electric propulsion which would not motor for 180 miles home and provide heating if not 'hooked up'.

Yes, I have wind and Solar generation but they would not charge batteries to motor that distance.

For a perspective...my two year old electric car...will do over 500 km on a single charge at motorway speed of between 70-80 mph loaded up for a vacation

I don't think marinas would need to upgrade much; only visitors would need faster charging than can be had from the ubiquitous 16A socket, supplying 5-10% of berths with 32A outlets is not much of a stretch. Unless you're referring to the minority with defective electrics; people will vote with their feet.
If the Toyota claims are true, marinas would only need some charging docks - the equivalent of fuel docks that you tie up to for 15 mins. I assume that whilst each outlet on the marina is rated for 15A if they all are connected and drawing 15A that something trips?
You could recharge what most sailors use using solar panels during the week. It would only need about 500w of panels. If you backed it up with a small generator you could get away with a much smaller and cheaper battery too.
essentially you are describing hybrids which are available now and are a serious consideration for new boats with big budgets! Some will have regen allowing them to charge whilst sailing.

I think 500W might be fine if you are in the med. if you are in the U.K. where everyone claims 40% of their diesel is used on heating, and outside of summer daylight hours are limited 500w might not be enough - especially if you actually use the boat rather than leave it tied up for 6 days a week.

TBH I doubt anyone will cough up for a charging dock, the premium for which would be sizeable, unless electric stinkpots start appearing. For yacht auxiliaries 16A is pretty much good enough.

your normal 13A socket at home can put out ~3kW, a proper home car charger will put out 7.5kW, some street chargers are about that but most of the smaller ones are 22kW, faster chargers of 50kW are fairly common (a big box size of a wardrobe), then motorway chargers are available in much larger sizes - 180kW+ already widely available. BUT many cars can’t charge at anything like that speed, so if turned into reality the Toyota claim is significant. Nobody is suggesting the would be charged at home at this speed - but you don’t need to because you will be asleep when the cheapest electric is available anyway.

But even with middle of the range cars you can already add about 30% to the battery in the time it takes to go for a pee and get a coffee, which if you are driving more than 2 hours is probably sensible from a safety perspective anyway.

‘Electric stinkpots’...a difficult term to justify 🤔

You're not seriously suggesting that drivers stop every two hours are you? Our usage has changed now but when we bought our current car we used to drive home from dinghy events regularly and it would take about 8-9 hours to do the 450+ miles from Weymouth to home... so an early prizegiving, full tank of fuel and a clean run could have us home for midnight and a reasonable night's sleep before school & work on Monday... From memory, a toilet break would end up adding about half an hour to the arrival time (never really understood why: slip roads, parking, walking to & from?), so if we stopped every two hours we'd be on the road until ~3AM!

I know this is not an electric car thread (we have a doozy of one in the Lounge)... I live near the Med and there are electric cars from all over Europe here for the summer...they somehow manage it

People love to cite ridiculous edge cases for EVs. Mrs Miggins will cope entirely with a car that needs a charge every 100 miles or so, as will Mr Average doing their 20 miles a day.

Newer EVs usually do over 200 miles between charges, even over 300 miles. I did a long run from Ely - Manchester - Edinburgh - St Andrews - Edinburgh - York - Ely over 4 days without any problems at all on a nominal range of 240 miles. Charging at a motorway high-capacity charger only takes as long as having a pee and getting a cup of coffee, and hotels increasingly advertize charging facilities. Even a 13 amp socket will give a charge overnight. I can easily do the run to and from my boat on a single charge - it's about 180 miles round trip.

It was more the suggestion that a driver would stop every two hours than the electric bit that I was disconcerted by. We were obviously something of a corner case.
Seems pretty clear that range/recharging is a constraint for a few but I'm not dumping on electric cars, just on the suggestion that stopping every couple of hours is normal!
I don't think many people routinely drive five hundred miles each way for a weekend.

I suspect most marinas would gladly get rid of their petrol and diesel if it wasn’t to keep the mobos happy too!

When I was young and stupid I used to regularly do a 5.5-6 hr journey and saw it as a badge of honour to make it all the way without stopping and the fuel warning light on.

I’m now of an age where even if I managed to go that long without peeing my back would be screaming if I sat in one place that long. I will do 3hours in one go, and my EV can do that. But if the total journey is more than about 300 miles the app actually calculates that it’s faster to stop twice (for 20 mins each) that to try and do it with one stop (because getting the last 20% in the battery is painfully slow).
I recently did the same journey I used to 25+ years ago in the EV with 2 short stops and it was much more civilised than I remember it being back then (I also didn’t have to turn the tape over every 30 mins!)

From memory, a toilet break would end up adding about half an hour to the arrival time (never really understood why: slip roads, parking, walking to & from?), so if we stopped every two hours we'd be on the road until ~3AM!
Only when driving our own cars would we think it’s acceptable to put a human being sitting in one place operating heavy machinery at speed for 8hrs - probably after having spent a long day working/sailing etc. if a truck / bus driver did that we’d be outraged.

To give you an idea: Southampton airport to Edinburgh airport (two random locations that I guessed would be about the right distance) is about 7h30 on google maps (via toll road no charging); the car charging app says 8h35 including 3 stops to charge and turning up with 15% left. Obviously that’s not towing.

So glad my kids were never that good at dinghy sailing to make that sort of trip a regular thing!
