Interaction between a current and surface-active material is considered. Some simple cases where the substrate motion is steady and 2D is analysed using standard boundary layer theory. Questions like: how is the transversal dimension of a slick related to the film pressure and the substrate convergence? and how strong substrate motion does it take to break up a surface film?, are addressed. It is pointed out that the answers depend on whether the film can be considered stagnant, or develops selforganised motion. It is further pointed out how small scale thermal convection at the ocean surface is easily suppressed by a slick.
