Wave resistance is typically the largest portion of the residual resistance. According to linear wave theory, energy contained in a wave is proportional to half its Humps and hollows squared amplitude. Thus, wave resistance is high if the waves in a ship wave pattern are high, which means a lot of energy is spent in creating and sustaining the waves. Ship waves tend to become higher with increasing ship speed. Humps and hollows are the effect of favorable and unfavorable wave superposition. This chapter explains the phenomenon of wave superposition and its effect on wave resistance with the wave systems created by submerged spheres. The first reasonably successful attempt to compute the wave resistance of a ship is attributed to the Australian mathematician John H. Michell. Michell derived an equation for the wave resistance that resulted in a triple integral. Today, panel methods are the most reliable way of computing the wave resistance of ships.
