This work addresses the experimental and numerical study of a stepped planing hull and the
related fluid dynamics phenomena typically occurring in the stepped hull in the unwetted aft …

The double-stepped design of lifting surfaces, planing in water, has been seen to benefit the
calm-water performance by distributing forces over the washed area. The unsteady motion …

Reducing vertical motions of high-speed planing hulls in rough water is one of the most
important factors that help a boat to become more operable, and will benefit the structure of …

In the present paper, the hydrodynamic performance of stepped planing craft is investigated
by computational fluid dynamics (CFD) analysis. For this purpose, the hydrodynamic …

Drag is one of the main factors in improving fuel efficiency. Various study in regards to
improve drag performance of a planing hull amongst them is a stern flap. The main …

Numerical Ventilation (NV) is a well-known problem that occurs when the Volume of Fluid
method is used to model vessels with a bow that creates a small, acute entrance angle with …

A numerical investigation is conducted in order to identify a PID control loop feedback
scheme able to return dynamics augmentation and superior seakeeping characteristics in …

This paper presents experimental and numerical investigation of stability and rooster tail of a
mono-hull high-speed planing craft with a constant deadrise angle. Initially, a one-fifth scale …

Speed and stability are two essential criteria for assessment of planing hull performance.
Accordingly, the effects of step shape on these vessels' hydrodynamic performance and …

One of the most effective methods to diminish the drag of a planing craft is to use a step at
the bottom of the hull. A stepped hull causes a reduction of the wetted area and, as a result …
