Motorized propellers have existed for 20+ years and are routinely used in spearfishing. What the heck is the news!? https://www.amazon.com/Nautica-Skipper-Seascooter/dp/B0BLP9Z...

I’ve always wished those were slightly cheaper and slightly faster.

4mph and under $250 and I’m sold!

There are a bunch of small watercraft I really want to try. It’s hard to justify the expensive.

The hydrofoil board with a prop and motor looks really cool.

Just not sure what the learning curve is like and kind of worried about hitting something and flying off.

I wish we could find a good way to bike over the surface of the water. I haven’t seen anything that’s not slow and cumbersome.

Anything you choose will be cumbersome because you can't create friction on the water (well...), your ability to move is based on your ability to move water around you.

There are solutions that leverage a pair of catamarans and a track system, or a prop. These tend to move very slowly, much slower than a canoe or kayak. The water wheel style systems seem to move faster, but you can just get a pedal kayak and will be the fastest human powered craft on the water.

Yeah; I re-read that article couple of months ago. The core notion about submarine articles I find very valid and as Paul suggested, fun to discover.

But... internet has changed massively since then, I feel; both the authors and reader audience are different in demographic distribution. I don't much subscribe to the notion that "Internet is dead", I think "old internet" is still there, just about as large with just about same interested audience, for those who want it. It's merely been... superseded, supplanted, overwhelmed? Whatever the appropriate word is, from early quirky adopters to general mainstream and varied audience. Back to the point though - the trust level of online content I feel has been drastically reduced since Paul's article, and with the AI content generated feedback loop we're encountering as we speak, it may experience a sort of "crash" in trust / consumption / economic model. We'll see! :)

I'm curious how this compares to using fins. Just at a glance, I suspect it causes more drag and is more cumbersome to swim with. But the big thing is if it's more efficient overall than fins.

Looks a more uncomfortable than the fins (especially the lumbar lordosis part) but I imagine this should be way faster than fins.
