The world's first smart, electric, self-inflating stand-up paddleboard
https://www.digitaltrends.com/health-fitness/sipaboard-electric-self-inflating-paddle-board/
It's waaay cheaper than the wad Trav blew on his project ...but not as cool.
I've been slacking. Need to take some photos and post the kayak project.
I'd particularly like to see the throttle set-up.

That solar kayak seems like a nice setup, though I think I'd want a small battery pack so I wouldn't have to worry about shade that much. Hack a Day is a pretty cool site.
Dang I've really been slacking on sharing that project here. It'll go all day at 3.5mph on solar (slightly faster than average paddling speed), or 5-7mph when you dip into the battery power. Battery is huge and can do 20+ miles solo on a full charge, depending on speed.
Zipped by a million-dollar power boat party in a no-wake zone last Summer. They got a kick out of it.
That's cool Travis! Post some picks.
Here are a couple from last year.
Running on battery

Hobie Mirage Revolution 13
Torqueedo motor
150 semi-flexible watt solar panel
Larger 915 watt hour battery
Custom PVC solar panel frame and lashings
The Torqueedo can charge via solar. I spoke with the engineers and learned that it is designed to flow solar energy straight to the motor. The digital throttle display shows current watt usage. With the solar panel wired up, you can go 3+ mph (cruising speed for this hull) without tapping into the battery at all. The throttle display will show no watts being used, and infinite range. Any increase in speed adds a logarithmic increase in required watts. I'll post some photos of that.
It's been fun exploring local waterways. Top speed around 6mph.
It required full registration and mandatory coast guard safety equipment like a regular boat, hence the (redacted) lettering on the side.
1st photo
68% battery remaining
--- miles range remaining (infinite)
3.4mph current speed (GPS)
0 watts currently being consumed from battery (all power from solar)
2nd photo
68% battery remaining
113 miles range remaining
4.5mph current speed (GPS)
22 watts currently being consumed from battery (remainder from solar)
Contemplating an outrigger kit. It'll allow for two additional solar panels. Full throttle all day, purely on solar.
Thanks for the pics and video. Does the motor stay above the water there on the side and then drive a shaft down to the propeller?
No, the motor outputs directly to the propeller. My one complaint of the system is the noise. But it's otherwise top quality. Torqueedo makes some pretty serious electric boating systems.
Hey Trav, this reminded me of your setup (https://www.youtube.com/watch?v=DNtvwc6kk_s). I like how the panel also serves as shade.
Yeah very similar DIY style. I had it easy, just bought some stuff and plugged it together. Thanks for sharing.
OK , so a little jet motor,

Or perhaps a smaller one, and then put these on the bottom......

Powered as a peddle unit, to use those big thigh muscles.
and you have a thing of real beauty:

now that combines both ideas, but in a tiny thing!!!!
>Or use this:
$13000 !!!

Looks like what Zuck was using the other day.
Never saw the price tag!!! but how cool!
Trav, this thread has got me going down a rabbit hole.
What is the power output of the prop and motor please?
I am about to buy a Chinese motor and battery.... I think I can make it fly :)
It's going to be fun to try.
It was 500 or 750 watts max I believe. Torqeedo Ultralight series. I'm interested to see what you build!
When I have something working, I will post inside :)

This your project, Rupert?
Zin Boats reinvents the electric speedboat in a bid to become the Tesla of the sea
https://techcrunch.com/2020/08/11/zin-boats-reinvents-the-electric-speedboat-in-a-bid-to-become-the-tesla-of-the-sea/
A friend got in early on the standup paddleboards (SUPs). I had never heard of them when he told me, as delusional people do, that it was going to go big soon. So... years later, he has bought up a large number of his competitors and is selling SUPs like mad during Covid. The main problem he has is that all his fabrication is in China and he is having trouble getting enough to meet demand.
Another friend with an outdoor gear shop is going crazy - they can't keep things in stock.
Anything that allows for outdoor recreation with social distancing (or not) is booming right now.

yup something like that :) perhaps a tad smaller.
seems boat dev is not cheap, but I have been enjoying watching the past documentaries on the Americas cup boats. I cannot believe Zin does not fly.

I need something to replace suits that sells. Suits are dead in the water still.
>outdoor gear shop is going crazy
I have been looking for some kayaks or SUPs to paddle around with the kids and they are very hard to come by right now, especially looking for used ones. Pretty much all the bike shops are sold out of most everything except for some $5000+ electric bikes and there is at least a 3 week backlog if you want to get a bike tuned up or serviced. I could see it being frustrating as a store owner to have all this demand but not be able to meet it due to supply chain issues.
This yours, Rupert?
