The Pontoon Design Optimization of a SWATH Vessel for Resistance Reduction

Journal of Marine Science and Engineering
This study applies a deep neural network (DNN) to optimize the 22.5 m pontoon hull form of a small waterplane area twin hull (SWATH) vessel with fin stabilizers, aiming to reduce calm water resistance at a Froude number of 0.8 under even keel conditions.

A Review on the Drag Reduction Methods of the Ship Hulls for Improving the Hydrodynamic Performance

International Journal of Maritime Technology, 2015
Hydrodynamic performance of a marine vessel mainly depends on the frictional and pressure resistance. Pressure drag reduction could be achieved by improving the shape of the vessels with implementation of modern hull forms.
