those from AUSTAL and INCAT (that ®ü®l¸¹) use water jet for propulsion so the "thruster" can work like "vector thrust" to improve maneuverability at swallow water or confine space, which is useful for ferries since they have to dock and make U turn quick without tugs helping.

one of the trick for catamaran to reduce drag is by reducing the cross-section area under water (§C¦Y¤ô) and so they are similar to sliding on the water surface
