ACC Stability and Seakeeping,e keel; and the stability of air cavity planing craft. An air cavity planing craft requires consideration of both stability at rest in displacement mode and when travelling at design speed when the principal forces are kinematic.

ALS and ACC Propulsion,mploying air lubrication has a stream of bubbles moving through the propeller stream tube which will affect its performance. A propeller located behind an air cavity will also be subjected to a vortex stream of air, vapour, and water as it flows past the stern ramp or closure of the cavity.

Rudolf Petersen,Harald Diaz-BoneA planing hull is supported almost entirely by dynamic forces and so its elevation and trim angle relative to still waterline vary uniquely with forward speed. In this chapter we will look at the influence of various hull parameters on the drag and trim of a planing hull and planing air cavity craft (ACC).
