Mechanical design of engineered-curved patrol boat hull based on the geometric parameters and hydrodynamic criteria

Curved and Layered Structures
This comprehensive study meticulously analyzes the hydrodynamic performance of various patrol boat designs to enhance maritime security in the Arafura Sea, Indonesia. We evaluated three hull types – monohull, catamaran, and trimaran – based on resistance,

Anti-slamming bulbous bow and tunnel stern applications on a novel Deep-V catamaran for improved performance

International Journal of Naval Architecture and Ocean Engineering, 2013
While displacement type Deep-V mono hulls have superior seakeeping behaviour at speed, catamarans typically have modest behaviour in rough seas. It is therefore a logical progression to combine the superior seakeeping performance of a displacement type ...

Bilge keel design for the traditional fishing boats of Indonesia's East Java

International Journal of Naval Architecture and Ocean Engineering, 2019
Seakeeping, especially for the roll motions, is of critical importance to the safe operation of fishing boats in Indonesia. In this study, a traditional East Java Fishing Boat (EJFB) has been analysed in terms of its seakeeping performance.

The Evaluation of Seakeeping Performance of a Ship in Waves

Journal of the Society of Naval Architects of Japan, 1984
In this paper, a synthetic method for evaluating the seakeeping performance of a ship in waves is studied.For the prediction and evaluation of irregular phenomena to be correlated each other, the multi-dimensional Rayleigh's joint probability density function and the cumulative distribution function are approximated.According to this approximated ...
