One with a thicker foil shape. That is the difficulty with making blades from flat stock. Thicker foils will hold the water flow better under turning loads and not cavitate as easily. Next best is the larger and deeper surface area. Generally... like airplane wings. Larger thicker for slow speeds. Flatter for higher speeds. PAs would fit the slower speed category. |
