A projectile can be fired at a surface vessel and, upon impact, an air bag may be deployed almost instantaneously from underneath the vessel. Through the rapid inflation of the air bag, the stability and orientation of the target surface vessel may be disturbed. Disturbance, at a minimum, may reduce and change the trajectory of the surface vessel, but, in some circumstances, the surface vessel may be overturned. The air bag may be designed with an anti-slip coating to directly couple to the wet hull of the surface vessel. In some embodiments, the projectile may include a delay to enable the air bag to be positioned under the vessel before inflation thereof.
