Wow, this technology is quite fascinating! It's possible that they might consider updating it to a more established version with greater capacity, which has been known and is operating since 1961. https://ru.wikipedia.org/wiki/%D0%9C%D0%B5%D1%82%D0%B5%D0%BE...

Perhaps you meant the "Caspian Sea Monster" [0] or similiar Ekranoplans? [1]

Earlier quoted context omitted.

It's electric, whereas most boats still use pretty dirty fuel sources, however the damage possibilities from direct collision with wildlife are real.

Wrong kind of environmental concerns from what locals have told me. The issues were more about increased traffic from Oahu to the less populated islands and people taking things that have been made more or less extinct on Oahu like opihi or the lava rocks used for cooking kalua pig.

I thought the problem with the ferry was not doing the underwater environmental review

> A preliminary survey of Hawai‘i residents showed they are concerned that seagliders will only be affordable to the affluent and may result in an increased tax burden on Hawai‘i’s residents. The survey also showed that residents are concerned that seagliders may produce some form of ecological damage either near shore or in the areas surrounding the harbors. Others expressed their concern about how seagliders can po…

pricing was projected to be pretty cheap compared with interisland flights today

It's an ekranoplan. The USSR made several. The actual vehicle is from a company called Regent.[1] They do have a quarter-scale prototype, and a video. This web site is from some group trying to get funding for a service.

The current Regent ekranoplan, not yet shipping, is a 12 passenger model. That seems small for an inter-island ferry. It would be faster than a ferry, but since the existing inter-island ferry routes only run about an hour, more speed may not be worth the trouble.

Probably just a tourist attraction.

Wasn't there a ferry transportation service that got canned due to environmental concerns? Seems hard to imagine planes doing better on that front.

its a ground effect plane - they can be a bit more efficient vs traditional ferries and airplanes especially in a role were it just relatively short hops between islands. Also since its effectively float-able by design it has the potential to be very safe even if its propulsion breaks during the trip. you could just send another plane to take the passengers off then take the broken plane home pulled by a ship. This c…

Can a ground effect plane really be more efficient than a ferry or a hyperfoil? It just seems like a boat that can carry cargo etc would be useful infrastructure instead of a fast taxi service. Pour que no los dos perhaps...

To be clear, what I read about the ferry service being shut down made it sound like Hawaii has some dysfunction preventing good and normal things from happening, just sounds like this would be less feasible

So then the question becomes: does a theoretical "boat with electric motor" succeed more or less with energy efficiency. I say theoretical, but I feel like you could take any ferry and replace the motor with an electric one? Maybe that's not true.

Something also planned for New Zealand too: https://www.oceanflyer.co.nz/

Neat! I couldn't see where they intend to run it (though it may be hidden in an article). They give a 300km range, which is almost exactly Christchurch–Wellington, so I wonder if that's possible.

The superferry was canned because of lobbying by airlines and car rental companies.

Currently, the only way to travel between the islands is by actual airplanes, through airports, with all the annoyances that comes with that, TSA, security, bag checks, prohibited items, and a gazillion other rules. That's what this thing will compete against, and it's pretty much a slam dunk.

Unless it will be lobbied to death like the predecessors.

The Ekranoplan, or so-called Caspian Sea Monster, was truly massive, and could no doubt fit several of these puny tourist versions in its hold. For these kind of endeavours you'd really want to go big or home - there's a limited enough tourist market if all you're planning to transport is some sightseers without any luggage!

Something that could take a few shipping containers, automobiles, passengers etc. however, you'd think there would be a greater demand for something like that.
