All you need to do is divide the battery kWh capacity by the claimed power output. It won't be very long. The trouble with this application is that it's pretty easy to use full load, or close to it, without actually going all that fast. Boats are thirsty.I saw a EV jetski the other day. I asked the guy how long it go for before needing a charge.
"up to 2 hours" is the answer I got...
"okay, what does that mean exactly.. 2 hours of coasting? 2 hours of slow riding? 2 hours at half throttle? how long will it last if I point it into open water and hold it wide open until it dies"
"It will last for up to 2 hours under normal use"
"No one at your company has done a WOT range test?"
"All I can tell you is the battery will last for up to 2 hours under normal use"
Electric short race boats may be competitive soon (heavier than ICE but can probably make up for that by having a much broader torque curve and faster reaction to "throttle"). Electric assist sailing or local cruising is probably viable now. As you say, boats (and planes) have a constant high hp draw and minimal regeneration so for now, they are a horrendous fit for BEV. Sure, you can make it work for an order of magnitude more money and an order of magnitude less range but that's not the market most people are in.All you need to do is divide the battery kWh capacity by the claimed power output.

My understanding from physics (and memory) is to double or half speed for a boat in water is roughly 8X factor in power required. Of course there are other variables but that is a good starting point. So speed is a big multiplier....25kwh with 160hp.. I'm getting 12.5 minutes.
Should I assume it'll be less when factoring in the resistance of moving thru the water?
I would not be excited to slam my fingers in any vehicle door. The anti-pinch sensors they talk about are only for the last small pull-in, the smash from swinging the door would have already molested you. Focussing on the damage EV's cause is just clickbait fud. It's hard to find a vehicle that you could slam your hand in an come out unscathed. Car would need to trap the swing well out (gap 4" or so) and then slowly swing it in with pinch protection activated or be entirely power swung with no ability to throw it shut with your muscles. I don't know of a single car that that a long power pull in. As for full power doors, I assume the X has full-power on the falcon doors but I am not sure how they behave if you pull them shut.New feature unlocked on the Cyber Truck...
Reviewers show Cybertruck 'guillotine effect' could slice off fingers
A viral 'carrot test' shows Cybertruck's stainless-steel hood can slice off through a carrot or finger. 'Guillotine effect' has been attributed to the electric vehicle's thin body panelswww.dailymail.co.uk
Oh I know...I remember had a first date many years ago and as she was getting in the car, I didn't notice she was holding the top frame and slammed the door almost crushing her fingers.I would not be excited to slam my fingers in any vehicle door.

When I was a small child, I was inside an 80's GMC truck when the door was closed and my fingers were poking out outside. I was very unhappy but thankfully no damage. Yay for big panel gaps.
People will buy them. There is a Taycan Turbo S at the ski hill often. Young asian guy. $230K daily driver.Porsche Macan EV revealed
is it just me or is the pricing out to lunch? Canadian site showing 106k starting base price and turbo at $137
current ICE base Macan is 70k, top spec GTS is only 99k.
or buy a Cayenne for the same price and actually be able to haul stuff + people.
I'm excited for it, even though I'll never actually be able to afford it. But people will buy it, otherwise it wouldn't get made / sold here.Porsche Macan EV revealed

Still a sales champ! Keep production rolling...
The market agrees....They still "do it best"
