At four times hull speed the wavelength is already 16 times longer than the hull. Wave-making resistance Wave-making resistance is a form of drag that affects surface watercraft, such as boats and ships, and reflects the energy required to push the water out of the way of the hull. This energy goes into creating the wave. For small displacement hulls, such as sailboats or rowboats, wave-making resistance is the major source
