Abstract of the Disclosure A method and composition for decreasing water resistance to movement by decreasing the surface tension and diminishing the contact angle between an object moving through water, and the water, and/or between water passing over an object and the object, thereby allowing the object to move at increased speed with the same applied moving force or at the usual speed with less applied moving force. The method is accomplished by applying to the surface of the object which is to be moved through water a thin layer of a nonionic surface active agent which is water in- soluble with the agent having a hydrophile-lipophile balance of about 7 to about 9.
