EV technology for your next boat ???

There are a lot more cars than leisure boats so in that sense the emissions from boats isn't a big deal.

That's a very tough case to make when the optics to the public are "rich blokes with yachts" wanting to keep burning diesel when they're not allowed to...

I think the ICE on boats issue is a lot about optics and politics. I'm actually amazed that no politician has yet said "wait a minute, we're phasing out new petrol fiestas, but not new motorboats that use more fuel in an afternoon than a fiesta uses in a year..." The optics of "1 rule for the stretched single mum who needs a car to get to work, and one for the rich people with big boats" isn't a great one. Especially where you've phased one out because of the CO2 footprint, but not the one with a much higher CO2 footprint....

On the assumption that as EVs become the norm smaller and smaller tows will start putting ULEZs in place, and that picturesque tourist seaside towns will be fairly high on the list of towns where the council decides to go that way, then it's a strange situation where the cars driving into the town must comply to a set of air quality rules, but the leisure boats on the harbour don't....

You’re not wrong. Ships are even worse!

BYD TRUCKS

Electric Truck with 200km range :unsure:

200km is 125 miles. If that's 'official range' then, if electric cars are anything to go by, it could be as little as half that in the real world, so about 60 miles. Truck has to get there and back (unless you're willing to pay for a vehicle and driver to be out of action for a few hours of charging time when they could be out delivering) so what we're really talking about is trucks with a depot to destination range of 30 miles...

Given that politics has little to do with common sense, I fear you may be right.

However whilst the 'headline' that a big motorboat uses more fuel in and afternoon than a car does in a year sounds dramatic, I suspect that if they actually looked at (for example) how much fuel was used by cars today compared with how much was used by leisure boats today, it would be clear that leisure boat fuel usage is virtually immaterial by comparison (and that's on a hot sunny day! Try it again in January).

However, as you rightly say, politics is driven by optics, not common sense (see lockdowns, face masks and school closures for perfect examples).

Thank you for confirming that it is already happening which was what I originally said.

But that has been happening for a long time and is not any progress towards an all electric boat which was the original question. This is still a hybrid boat with a larger than normal battery bank to increase its miserable range under power and run the domestics for a bit longer without firing up the diesel. No "new" technology involved,
 
When liquid fuel is no longer easily available retail…then it might be difficult to find it in a marina
 
P-12 - The Fastest Electric Ferry

This is the follow on from the hydrofoiling C8. I can't see big heavy planning boats ever going electric, but hydrofoiling definitely. Stick a few beds and a loo in the P 12 shuttle and you have the basis of a great day boat. The next gen batteries are coming through now with 450 wh/kg.
 
Still nobody commenting on the 600V DC in the engine room.
Do you realise the power involved.
I know we are only talking volts here but the extra voltage over the 24v that we are used to will make the terminals very dangerous.
Just imagine all that electrical power available at a 600V DC terminal that can suddenly release a huge number of amps that you would have stored to drive the boat.
Do you all realise just what that power can do?

What do you replace my 2400Hp ICE engines (needed to get my 50 ton boat planing) with?

Nothing, people will be using diesel for a long time yet.
There are some applications that may never move away from liquid fuels. What will change is what and where those liquid fuels come from.
Ships and Airliners make up about 2% of total CO2 emissions, so a long way down the to do list. Big planning boats probably dont even register as there are relatively few and they dont get a lot of use.
