• There seems to be an uptick in Political comments in recent months. Those of us who are long time members of the site know that Political and Religious content has been banned for years. Nothing has changed. Please leave all political and religious comments out of the forums.

    If you recently joined the forums you were not presented with this restriction in the terms of service. This was due to a conversion error when we went from vBulletin to Xenforo. We have updated our terms of service to reflect these corrections.

    Please note any post refering to a politician will be considered political even if it is intended to be humor. Our experience is these topics have a way of dividing the forums and causing deep resentment among members. It is a poison to the community. We appreciate compliance with the rules.

Tim, I was going through the latest issue of Aerotrader, grinning at airplanes, when I ran into a weird thing called the Sea Phantom. So I went to their web site and it's real and they have movies showing it under test. It's ground effect vehicle and it goes wicked fast.
It's weird enough that you might want to take a look at it for future references.

Interesting. But it seems more like a hybrid-hydrofoil rather than a WIG.

In the videos it never actually loses contact with the water. In fact it needs contact with the water to impart directional control. I'm not sure you can say it "flies" since it's never totally in the air and out of contact with the surface.

There is a difference between Wing in Ground Effect (WIG) vehicles and Ground Effect vehicles, the former being more like aircraft. Ground Effect vehicles use the effect to create lift and reduce drag while not leaving the surface, WIG don't have contact with the surface, and in some cases can leave ground effect altogether.
It's not a hydro-foil as they have wings in the water to generate lift.
Things like this are sort of on the boundary between a number of different technologies so to some extent it ends up being a matter of semantics as to what something is called.

Well, whatever you want to call it, it doesn't 'fly'.
