Well this is disheartening.
Perhaps the 1'st thing to do is collect some data. Make up a crude test vehicle, weight it down appropriately, then drag it about on the lake. Using a HD fish scale I could measure the force needed to drag the test vehicle and from that figure out what torque, and therefore hp, is needed. Then all I've got to do is ask Lance what torque his weak sister could apply and voila, I'll know whether the whole concept is feasible or not.
