Well, ANY scheme that will turn pitching motion into forward propulsion will reduce pitching - simpoly because the energy that is going into the propulsion is...
To all Prout cat owners: Hobby-horsing is an annoying feature of hulls that are of almost equal section at bow and stern. Unfortunately prevalent among Prout...

I once did some experiments with a 1/8" thick x 7" x 30" aluminum plate. I drilled a hole midway in the 30" dimension and 1" back in the 7" dimension. It was...
Now you have caught my attention. I've been working (playing) recently with kiteboards for very lightwind and/or best VMG. I'd been dismissing all these...
The flat plat design I used was suprisingly effective. If I were going to experiment, I would start with a thin symetrical wing section, a piece of aluminum...

Cory, Maybe you could make a "whale-tail" and associated trailing arm that fold up into the bottom of the kiteboard so as to form a flush surface when it's...

There is no need for stored energy, the car accelerates from a standing still to faster than the wind all by its self. The current gearing, read that as angle...

AYRS has a short piece of video of the Airchair foil (see AYRS #118 pub 1995) in a test rig when Cory Roeseler was trying it with a kite. Because the main foil...
