text: Wave-making resistance depends on the proportions and shape of the hull: many modern displacement designs can exceed their hull speed even without planing. These include hulls with very fine ends, long hulls with relatively narrow beam and wave-piercing designs. Such hull forms are commonly used by canoes, competitive rowing boats, catamarans, and fast ferries. For example, racing kayaks can exceed hull speed by more than 100% even though they do not plane.
  Heavy boats with hulls designed for planing generally cannot exceed hull speed without planing. 
  Ultra light displacement boats are designed to plane and thereby circumvent the limitations of hull speed.
  Semi-displacement hulls are usually intermediate between these two extremes.
