It would be pretty fantastic if this could go San Francisco to Los Angeles. A traditional plane flight takes so long at the airport, it ends up barely worth it. High speed rail in California would also be great, but they've been working on it for 15 years already, and at this rate, it doesn't look like the project will finish in the next 50 years.

Even San Francisco to some of the smaller CA/OR coastal towns would open up a lot of vacation potential. I really hope this seaplane works out!

What are the operating limits in terms of weather? At only 10m above the surface, I assume bad things could happen in stormy conditions! I'm guessing these will be best suited to sheltered areas and fair-weather tourist operations?

It has three modes of operation: hull, hydrofoil and flight in ground effect. So it can operate as a slow boat, a fast boat or a ground effect plane. I imagine in bad weather it would switch to a slower mode.

Yeah a high speed ferry of Fisherman’s Wharf > Monterey > SLO > SB > LA > SD would be incredible. I’d pay a nice premium for that.

Or crossing the Long Island Sound.

We've sold over 467 seagliders with a $7.9B order backlog spanning global aviation and ferry customers.

I would think this is pre-launch sales. It's probably hedged with "subject to certification" risk, but it's still pretty solid, and if it came with sufficient deposit fundings to bootstrap the assembly line, all to the good. But, my understanding is that both boats and aircraft (and this is a join over the two) incur pretty high compliance costs for insurance and regulatory certification. Its a long slow process, it is not as simple as "do it in the USA and it's done" by any stretch.

(their FAQ says: "REGENT’s seagliders are regulated as maritime vessels, not airplanes.")

Many transport manufacturing startups come unstuck with actually making product. Real-world consequences to advanced materials, the massive cost-suck of making the goods repeatably buildable without a huge tail-cost of remediation, digging out from development cost, it's a nightmare.

I'd love this to work, Having flown as a passenger on small aircraft island hoppers in New Caledonia to get to Isle des Pins and like places in other countries, There definitely is a niche for "get from A to B, with sea between" which this suits.

It's also possible there's a set of marine/air conditions this is better than aircraft for: it stays below 100m would make it much easier to "fly" in some conditions. Equally, if its really only coastal/lake waters and not when its more than 2m swell (arbitrary figure for example purposes) then its launch conditions could be highly variable.

Could this to Vancouver to the Island? The Island to The Olympic peninsula? Seattle into the sound? Could it make the Catalinas from California coastline? Or Baja Cali to the "mainland" of Mexico?

Unfortunately, at their stated range of 160nm, you're looking at only getting as far as Big Sur before the entire craft needs a recharge - it's much more aimed at island and port hopping, I suspect, than long distance travel.

Still, I am excited to see ground-effect vehicles/ekranoplans back in vogue!

"In high winds, take-off must be into the wind, which takes the craft across successive lines of waves, causing heavy pounding, stressing the craft and creating an uncomfortable ride. In light winds, waves may be in any direction, which can make control difficult as each wave causes the vehicle to both pitch and roll. The lighter construction of GEVs makes their ability to operate in higher sea states less than that of conventional ships, but greater than the ability of hovercraft or hydrofoils, which are closer to the water surface. The demise of the conventional seaplane was a result of its inability to operate in rough sea conditions even while flying conditions were good, and its use lasted only until runways were more commonly available. GEVs are similarly limited."

It can't, at least not nonstop: 160 nautical mile range, and SF to LA is about twice that straight line, and even longer following an overwater route.

The planned 400nm range nexg gen battery tech upgrade is probably in the neighborhood, though.
