Dear '100mpg'; can't believe you saw it! No more than one of ten thousand would recognize Mr Lipphischs' reverse delta in the plan-form. He and his grandson are heros of mine. A freind in Canada did a reverse delta-diamond mod on thier seaplane. Results speak for themselves.
Website talks of lifting bodies - actually shape looks far more like reverse delta with anhedral that Alexander Lippisch designed - great for transitional longitudinal stability in and out of GE.
Sadly, yes. Doing everything in my power not to follow in footsteps. But that's the point here. Trade off a bit of efficiency for safety and practicality. Give it an economic reason to exist. And it just might thrive.
Yes, on both observations. Airfoil is both lifting- body, AND reverse delta-diamond. Mr Lippish pioneered this, but latest reference was a personal freind's experimental delta-diamond addition to his Lake Amphibian. Ground-effect charactoristics were indeed outstanding!
Well done so far guys! Now let that baby fly like a proper WIGEC. The spike like retractable hydrofoils are good. But keeping the tail in the water means you can't jump over obstacles and your still get hydro drag. at the rear end
Cannot jump over obstacles, but by all indications; will outmaneuver anything else on the water. Inherant bank-turn ability will carve a turn out at up to 30 degrees. Kind of like carrying around your own banked oval.
Lift completely off the water? Yes, in theory more efficient. But if one is to go through all the time and trouble to make a 'boat' operate in complete free-flight... Why not just build an aircraft? We are filling a market niche here. Just because something can be done, doesn't mean it should be. Again, realistic economics comes into play.
that thing is stable!

The best WIG I ever saw was the Flarecraft. It went bankrupt in 2000. Sadly, most innovative companies go bankrupt.
