If I were to do this, I would choose a flat bottom hull, like a river towboat.
This, to keep the bow from rising (excessively) out of the water, as you begin your aerobatic (?) tow.
To give manuverability, I would have (linked) rudders at each end of the hull.
Like 4-wheel steering on a car.
And don't skimp on rudder size.
Instead of the pushing towers (on the front of a towboat) you could use a coarse screen, the kind used to protect flower beds. Even if it is in the weter, the drag will not effect your "capture". (Unless, of course, you plan to race "recovery" boats).
