very cool... but the rig is impractical for your average sailboat
Couldn't agree more. It's not a thing of beauty but it is form follows function to amazing results. The fact that it creates apparent wind and then uses that aparent wind to increase speed ......... if you carry that thought through, it could potentially continue to accelerate to amazing top speed.
Before you say that's not realistic ........ I remember when respected scientist calcualated, HP, traction and aerodynamics to determine that dragsters would never exceed 150MPH in the quarter mile.
How'd you like that thing spinning from the top of the mast????
Put that rig on a cat you might have a pretty fast boat; deadly fast!
Doubt it'd work too well upwind.
