electric catamaran boat to set world record

[Beak Boater]

As a comparison...a 30 Liberator with 300R's went 87 on the same course. Impressive for the electric boat for sure....but I'm thinking those Electric outboards are a little stronger than 180 hp

That's impressive! And they are 180 hp? I wonder if that speed could be duplicated with 300R's?

Said they were tuned to 340 hp. So life span of motor is shortened as well? I would think so.!

What's wrong with a social debate...isn't that what this forum is about? Sharing thoughts and ideas. Maybe I misunderstood you. dunno

To some extent, it's good. But this is the general boating sub forum. There's a dumpster fire of a political forum below, that oddly enough hasn't changed a bit since the unfortunate passing of the moderator of that forum. And that garbage little by little, by the same morons that do it down there, is making it's way up here. Libtard this, commie that, blah blah blah. Most all of their "points", if thats what you want to call them, age like potato salad in the sun on a warm day.

I've always found problem solving and engineering interesting. This is an example of both, and congrats to them taking this on. That's a beautiful boat, and.combined with the motors, hauls ass. I doubt the people doing the never ending bashing haven't even been in an EV or 4 stroke powered hi perf boat. Just sittin on the porch, barking like lap dogs. The point of the thread was to showcase a boat screaming and flying. But like always, the same culprits come in and piss in the punch bowl.

Google says there is a 25 year difference between when IC and EM were invented... so they've had 25 more years to make electric motors work and be efficient and they're not there yet. I have no issue with electric cars, boats whatever, I just take issue with the argument that they are greener than other power sources.

Shaun said he used $5.00 in electric, that's good mileage

Solar panel efficiency is now going over 20% and getting cheaper

Think just about everyone has said it’s cool and quite an accomplishment. The debate is about electric powered vehicles in general.

$5 in electric in a 3/4 mile pull? that's not good mileage at all is it? what's a normal 2.5 burn, 20-25 gallons per hour? That's roughly $70 to $88 for premium where I am right now for an hour of use. A 15-20 second pull used $5 in energy, seems pretty "thirsty" to me.

In fairness, he said $5 for the weekend which includes two 3/4 mile passes at 680 hp total, plus the especially thirsty acceleration distance plus the return ride and any other testing that was done. How much fuel would triple 2.5’s use doing the same? More or less than a gallon?

the motors were setup to have 340HP peak

Turboeddie would know the top end speed with 300Rs



.

Wow I didn't know they could make 340hp! What is the weight, compared to a 300R?

hey Gary, the motor that ran in LOTO is a specially prepared motor with a racing mid section and racing lower unit, thus the weight would be different than the standard Electric Motor distro






specs says 414 pounds

That is a much different scenario, $5 for the entire weekend. If it dropped 13% on a single run, expect probably 50% total use for runs and returns over the weekend? $10 in electric to charge it fully, that's better if that's the case. Overall range not being taken in to account, that's not a bad full charge price.

I wonder how much the batteries weigh. Never saw that anywhere unless I missed it.

[XstreamVking]

Seems I have seen Tesla’s do a big charge for 50-60 bucks. range is 300 at most

I worked out the math both ways and the electric cat gets about 4x the mileage/$ vs a gas engine. $5 will get you 38 kwhr at published Missouri rates. That’s 51 hphr, so you could run a 50 hp motor at max power for 1 hour for $5. Or for the same amount you could run 680 hp for 4.5 minutes at wot, er, 100% duty cycle or uh wide open rheostat?

I would be all for an electric assist when they get the battery weight down. Biden is getting ready to fund research of built in charge strips being placed in our National highways of major cities. We would be better off policing the rest of the world to our current standards rather then spending crazy money chasing the small percentage of emissions we have remaining from new cars. The first 50% reduction is pennies compared the remaining 50%.

One of the papers had a journalist do a story on driving an electric car from New Orleans to Chicago and back, over a weekend.

Was an abortion!

Spent all weekend waiting on charging and absolutely hated it!
