One of the big problems with wind vane steering is that they don't
work well below 3 knots or so because the foil in the water doesn't/
can't generate enough lift to move the steering device, be it tiller or
wheel.
So, I'm wondering how one would design and build a foil to maximize
power through water at low speeds. Would longer or wider or fatter be
better? Would a wing on the bottom help at such low speeds?
Impossible dream?
