Stern launching ramp

Some modern patrol vessels are equipped with a stern launching ramp, or simply launching ramp, for deploying smaller rescue or pursuit boats without requiring the parent ship to first come to a halt.^[1][2][3] Typically the smaller craft are powered by water-jets, and can drive themselves up the ramp by their own power.
