Nobody wants to talk about the real solutions that are boring apparently

Is it a real solution when for some strange reason it's impossible to build them? Also I love trains. I moved back to Miami and there is a train called Brightline that goes from Miami to Orlando. It's extremely nice and my preferred mode of travel. Imagine if we had a bullet train that just spanned the entire east coast...

Eminent domain isn't that popular anymore unfortunately. Florida being one large empty red state, it's a lot easier to muscle 500 miles of new track into what's already there. To go up the whole east coast you'd have to wrestle with a half dozen different political machines. Even just limited to Florida, the line hasn't gotten past West Palm (yet), and was stalled for years due to lawsuits from just 2 counties.

Realistically you'll see that sailboat in advance.

At 100+mph?

My sailboat uses radar, I can see things from a good distance away. Let's say 30NM. Surely the plane will do better. But let's say it's going 180mph, or ~160kts. That's 11min from first radar contact to collision. With all that forewarning, avoiding a yacht isn't a big deal. If they can't avoid it, they can stop with 11min warning.

Let's say visual only. There will be restrictions on visibility for visual flight rules. So say that they can only fly with more than 10NM of visibility. That's still 3m45s to take action. Surely enough.

There are rules of the road for seafaring which apply even to these types of craft. A sailboat usually wins over a powered craft.

so if a sailboat suddenly veers into the path of this thing, what is it going to do? Collide or ditch "GEVs may be unable to climb over or turn sharply enough to avoid collisions, while drastic, low-level maneuvers risk contact with solid or water hazards beneath. Aircraft can climb over most obstacles, but GEVs are more limited. "

Boats can't fly over things either. You crash or follow the rules and avoid.

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) inc…

Seaglider entry to service is slated for mid-decade so you're spot on, all these are pre-launch sales.

We're one of the few companies in the space with firm, nonrefundable deposits and contractually obligated pre-delivery payments (that scale with milestones as you mentioned) on the full first year of these orders.

We take off at the periphery of harbors and fly over the open water in-between. Seagliders have 5ft wave tolerance on takeoff and landing, and 5 ft waves in a harbor is basically a hurricane. Flyover wave tolerance is more like 8-13ft, since any higher than that is likely the result of conditions where commercial aircraft arent flying anyways. We definitely designed the vehicle with wave tolerance in mind.

And all your routes are spot on! It's super exciting. 180 mile range with existing battery tech - and as batteries advance through the decade, we forecast that range growing to 500 miles. 40% of the world's population lives in coastal communities... this is a massive market!

Hey guys - Billy Thalheimer, Co-founder and CEO of REGENT here. A friend reached out to say this is blowing up - so cool! (Thank you beefman lol) Here to answer any questions

How do foils deal with kelp or a casual whale?

We're exploring foil-mounted sensors (e.g. sonar) for whale (and manatee, turtle, etc) detection.

So far in our 1/4 scale experiments, the foils have shed kelp pretty well. Kelp is something the America's Cup boats and even hydrofoil ferries (like in Japan and Hong Kong) have dealt with and solved.
