Nice. But I wonder what happens when you wipe out.

Nice but not for me. I imagine the battery life for this might not be very long. And I wonder how much these electric foiling boards cost?

Look at it this way, the video is only 48 seconds long ;-).

Battery life being what it is (and using RC's as a guide), I doubt you'll more than a few minutes at the most....... that's a long paddle back to shore.

soon I get my moulds complete this is on the list I already have friends keen to figure the electrics out, shouldn't be too hard at all. maybe they we can get a full up wind and down wind experience without needing transport.

I would not pay $12,000 for this device. This is fine for someone who really enjoys going real fast on the water without the bulk of a big jetski. And who has money to burn.  ;)

With current tech I could easily fit  30AH at 52 volts into a hatch less than 12" X 12" in a board. The battery would weigh 15 pounds and probably power the foil for over an hour, maybe two if the drive was efficient. 1560 watt-hours. If the motor took 750 watts (three times the limit for European bicycles) the battery would power the foil for 1.5 hours.

The motor they are using does not look efficient. Looks like a motor and prop with a guard. A shrouded jet would give more thrust per watt.

A Panasonic LiPo battery of that size would be about $700-900 with BMS and charger.

You two are going to now suck me into yet another build? ;)

Pono, I'll bet the R/C and drone guys have the motors dialed and the batteries too.

Waterproofing would be a hassle but not insurmountable. I'll bet 2 units that could bolt onto each side of an existing mast with a deck mounted battery could make a conversion kit for existing foil boards.

Don't make me go buy a trolling motor off of craigslist. ;)

You could pack more power with RC motors--the graphene shielded batteries give one hell of a discharge rate for their capacity--5 amps at 30C--150 amps from a battery you can hold in one hand. But for long life and capacity for weight, it's tough to beat the 18650 Panasonic batteries--unless you could get your hands on some Gigaplant 21700 batteries.

I have four big ducted fan motors that I was going to build a drone with, but my Inspire2 has killed my drone building impulse. It would feel like I was building a Celica when someone had given me a Ferrari from the future. The fans aren't designed for water, but so what? Just means the pitch will be wrong.

Celica, now there's a blast form the past,  20R engine, more suitable for a forklift...

Back to the Lift foil. There were a couple of things that I find interesting with this foil.  The mast is attached using two parallel longboard boxes which could be ok, in-fact could be great.  But, the second thing, the need for a handheld remote feels like a step back to me.  After logging over 100 miles on my Onewheel, I would have a hard time going back to a handheld remote.  I would think that a powered foil board could provide enough range in the pitch angle to make a lean-to-go system work.

Having said that, this is the most probable way that I will ever foil.  I hope to eat those words.
