A system and method for disabling a small boat comprises at least two hulls and an entanglement device disposed therebetween. In the illustrative embodiment, each hull is an unmanned underwater vehicle. The system is launched from a vessel to intercept the small boat. When close to the small boat, the separating distance between the two hulls is increased, thereby deploying the entanglement device and causing it to become entangled with the small boat (e.g., the small boat's propulsion system, etc.).
