Lot more on their own website.

413 lbs, 188kg & you need to be able to access charging facilities. 'You can recharge your batteries at any marina or your personal dock, using a 220 V power outlet.'

“Our estimated range is 70 miles at a cruising speed of 20 mph or 3.5 hours.”

That seems pretty usable for some common applications. Especially if owners can plug it in at Yarmouth while they have lunch before heading back to Lymington.

Super yacht tender springs to mind, or harbour water taxi.

Nope unless it's a lengthy lunch.

How long does it take to charge the battery?
You can fully recharge your battery overnight
No info at all about the achilles heel, charge rate, dimensions, weight etc, just the capacity and type.

Advisable to partner it with a petrol aux

Wouldn't want the job of rowing the extension lead out to a mooring in the rain!!

As per PD I think a superyacht tender would be quite a good application.

In the motorbike world, a number of manufacturers are looking at a common battery to try and overcome some of the range / recharging issues.

presumably those who can afford such a craft don’t go to the Isle of Wight for a meal deal. But you’d almost have enough charge to go all the way round the island without stopping with 70 miles range and I suspect many luxury craft in the solent never go that far!

The charge rate will likely be limited by the outlet capacity (eg 3 pin plug vs fancy rapid chargers) rather than rapid chargers. The “charge overnight on 220v” suggests to me it’s similar to an electric car - many of which will do 20%-80% fast charging in a good bit less than an hour. You could imagine pontoons at luxury marinas and restaurants offering that if their was demand.

NOT a good time for your battery to give up or have an underpowered electric outboard!
Boat nearly goes over edge of dam

"Police said four women were on the electric boat when it got swept up in the current near the dam and wasn't strong enough to escape, according to FOX 7 of Austin.
They approached the dam, weren't paying attention, they were talking to each other," said Officer Brad Smith with the Austin Police Department."

Certainly doesn't light my Bulb!....18 knots Wow!...we know how industry "tested range" and for that matter "guaranteed immisions" stack up in the real world already!.....let alone "Estimated!"....
Wonder what the Hole Shot is like in the Rough?
The Briney and ordinary 12v electrics are bad enough!

Still ...the price MAY Entice the better heeled Greens ....Self righteous self flagellation ...and virtue signalling seems to make a Premium for some

Even "Elon" knows the limits of Batteries....you seen Space X "fuel" plans lately?
Hope they didn't ditch the Drawing Board!

The torque of an electric motor is available all the way down the rev range unlike an internal combustion engine.

Therefore the ‘hole shot’ is likely to be phenomenal compared to a petrol outboard. Just as even a crappy electric car can thrash quite a fast car at a set of traffic lights.

I imagine electric boats will become more and more common over the next 3 to 5 years. Everyone said electric cars will never catch on 10 years ago...

Hole shot to Max of 18knts would be great eh!....WOT ...Up and down Big Waves......would that mean more Juice used?.....and maybe reduced range?
Still.... if you get low or worse run out of power just pull over into a recharging station eh?
Insurance questions would be intersting too.
Big differences between even off road ....and "off piste" Sea travel.
FAR from practical for the foreseeable future ...HYDROGEN fuel cells might win out yet
Incidently (if you do you're research) you'll find electric cars have been around for a Century or so

Be interesting to read this post again in 5 years time.

Electric boats are coming. Hybrid boats are coming even sooner.

Only a Luddite could deny that, however I think your timescale could be a tad ambitious.

Just look at the electric car explosion in the last year, and we haven’t see anything yet.

It always comes down to duty cycle. The reason a car can have so much range is that you don't use all that 200hp to cruise at 70, and when you brake, you can take the energy back into the batteries. A 8m rib with 200hp probably uses most of that quite a lot of the time.

Boats need a phenomenal amount of power just to keep going. So while there is absolutely a place for them, superyacht tenders, harbour launches, water taxis, riverboats, there's also an awful lot of of use cases where they're still crap. Nevertheless, battery technology improves every year. so it could, maybe even probably will, become mainstream eventually.

H2/O is the answer Particulaly for Boats! Of ALL SIZES!..
NOT heavy...expensive...hard to manufacture/recycle/transport ...energy sapping expensive to make ...toxic....rare element rich...weather sensitive"Batteries"

They invented Welders powered simply by WATER DECADES ago!.
Where by the the Hydrogen is separated from H2-0 (clues in the name) and used as fuel!!!....little or no immisions and ...a little water vapour.

If....When that happens for vehicular applications.Companys like Tesla ect ect will be yesterday's news!...once they DO the proper R&D into THAT branch of renewables and share the technology ....we will see some real progress!

...Or JUST maybe the "forces that be" and our huge international business...including the Far from de-funct Petro-Chemical Giants! and consortiums want to milk the Masses for every penny of every incremental step along the way!?
By the way ....while we in the oh so sanctimonious virtuous "West"...Navel Gaze and berate each other ...China and India are BOTH opening one NEW COAL fired Powerstion EACH per week!!.....often to power the Factories making the Batteries and Electric Cars and components for US!
