electric catamaran boat to set world record

[PanRonnie]

If you are bored

Long story short the charging stations are not build!
What he does not mention is where that electricity has to come from
Imagine all transport in the US is electric tommorow cars, trucks, river shipping we will leave planes out it
How big is the grid system needing to be 10 fold, 100 fold , 1000 fold?
In the netherlands we already have some area,s where new business offices cannot be build because off grid capability same for solar parks they cannot hook them up to the main grid because off capacity in that area
now shell is going to build hydrogen factory,s in rotterdam
so battery cars yes! boats and trucks i don,t believe
so the catamaran is halfway there just needs some rugged hydrogen fuel cells and someone with an unlimited credit card so that in 30 years people like me can dumpster dive for parts

I think its gonna take an electric powered boat to break the 200MPH outboard speed record on the water


I hear the torque is unbelievable on electric motors

electric motor wins over combustion in most cases.
Depending on motor design they can have the same torque from stall to full rpm.
That will win any drag race.
Problem is batterys need to be 20 to 50 times better than today. So do Solar panels.

Besides battery design and more efficient electric motors etc these electric products need to do what a car already does with its own battery, recharge itself. When an EV can be used without depending on external charging, they will have something. It will be costly complex. Performance applications ? Good luck. I think these vehicles like tesla are only here now to get people to bite on the idea

for a non plug in car to work, its going to need solar panels that dont yet exist or induction loop in the road.

The E-Motion™ 180E powertrain system can be rigged and custom fit onto virtually any 18 to 29 foot boat. Its powertrain technology is designed for 15 nautical miles of driving range. This is more than enough to cover the average family’s day on the water, which is generally around 9 nautical miles.

Then it needs an overnight 220 amp charge ?

So when I lived in FL it was 5-7 miles in a straight line out to the reef line. Very rarely would someone have a straight line, at best you drove around shallow spots. Often you had to take a trip to get to a point where you could begin your straight line. I would estimate 20 miles as a minimum for most going out on the water. The auto parts stores would sell an amazing number of batteries as people would have enough of a problem keeping a good 12v battery in their boat.

Electric cars are nice when they are new and perfect, but then so is every new car. Unfortunately the reality can be compared to power tools. Imagine having your only option for battery tools (considering you aren't someone who get a new car every couple years) being buying used and as old as the car you are driving now . . .Now an electric boat well now lets just say that those used power tools have been used outside all their life having never been maintained or kept out of the weather.

Down hill water fixes most issues with electric

[Instigator]

Hyundai and Kia just announced a 280k recall on their electrics.

Warning owners, do no park them in your garage!

Was on earlier, stating, do not charge over 80%!

Freagin hilarious!

And the joke of a typical trip being 19 mls, round trip!

Staying with a sunk/swamped boat takes on an entirely new risk. Saw a tesla stuck on the side of the road the other day (long stretch of nothing), guess they ran out of juice so a long tow then a very long recharge.

Considering they have been trying to work out the kinks for over a century I wouldn't hold my breath. Personally Im going to build up a new motor to run on brown gas. That plus a diesel genny and Im not worried about the grid.

Coal must be getting cheap

Not sure why this has to turn into a social debate every time one of these threads comes around. I'd think as a group of people that appreciate performance and technology, these kind of things would be better received. The whole "what aboot the grid " argument is laughable. Our electric transmission system is archaic as it is and needs upgrading regardless of EVs or not. I'm an electrician, I've worked on transmission lines, substations, and wind farms. Know what's a giant consumer of electricity??? Refineries.There's plenty of answers to your questions if you really wanted them. But go on, rabble rabble all you want. The future is coming with or without you.

The beauty behind EV's IMO is consolidation of pollution, and neck snapping acceleration. I love my gas powered stuff, the sound of a 2.5 or my Ducati V twin is pure sex. But when the time comes, I will have zero issues with flipping over to an EV.

Even when way more efficient solar comes along you need a constant source of sun (clouds, nighttime lol ? ) Maybe very efficient generator/alternator at all fours wheels providing a constant reliable charge ? Boats ? Maybe turn a sea strainer design into the same kind of thing ? Then again maybe we will skip right to the Jetsons

Apba should have some development electric racing classes but way down in single engine boats.
That will allow motor and battery technology to be pushed.
Lots of criteria for rules, volts, current, battery weight, time based duration races, etc.
Imho that might get sponsors interested.

If the goal is solely to drive up the cost of racing... they could use turbines or rockets.

Since there's no actual climate crisis and no gasoline shortages... non of this makes much sense. If not for government subsidies they would still he trying to find someone to buy the first Tesla.

If you really want an electric boat... you put avnuclear reactor in it, everybody knows that.
