alt Hacker NewsTBD but I'm hoping those constraints are largely in taxi mode! When it's flying it's much higher up:
> Like similar “Type A” WIGs, the Viceroy’s preferred altitude is about half the length of its 19.8-meter wingspan, so 10 meters above the water. Much above that and a WIG can no longer exploit its aerodynamic edge, and loses stability.
I really want something like this to work, ideally so successfully that it keeps scaling up. Theres such beautiful aerodynamic efficiency from WIG.
Also a huge fan of what looks like a very smart lift generating blown wing, which also could really help this get out of the water fast, give it good efficiency

There are hard scale issues. The wings must remain close to the water for ground effect to be a thing. But the thing still needs to bank to turn. That means one wingtip getting higher to the point it can lose GE lift, and the other lower to the point it might strike a bigger-than-average wave. The longer the wings, the less the craft can bank in a turn. Get too large and in-ground-effect flight becomes impractical/dangerous.
I guess you might be able to get around this problem if the vehicle can take off and land on a land based airstrip and then stay at 10m over the water. Otherwise that is a crippling limitation since you not only need the ocean to be relatively calm when taking off, but also when landing.
