Abstract T-foil and stern tabs were installed on a wave-piercing catamaran (Incat Tasmania Hull 061) to improve ship motions passenger comfort. More than 40 total effective hours of sea trials conducted by the US Navy in 2004, encountering states 4–5 Atlantic Ocean near United Kingdom. In this paper influence ride-control system (RCS) heave pitch response amplitude operator (RAO) full-scale hig...

This paper presents the development and field testing of multiple autonomous surface vehicles (ASVs) for cooperative navigation tasks in marine environments. The developed ASVs were designed a catamaran hull form, various systems related to functionalities, including electrical propulsion, wireless communication, guidance, navigation, control (GNC) systems, integrated with situational awareness...

A prototype energy scavenging autonomous marine surface vehicle for littoral water surveillance has been developed and experimentally tested. The basic vehicle chassis is a heavily modified Stiletto Catamaran with the center structure removed and replaced with an aluminum box beam supporting a carbon fiber stub mast. A carbon fiber rigid wing, 10.7 meters tall and with a 3 meter chord is suspen...

Juvenile salmonids in streams typically feed on larger invertebrates than the average size available in the drift. Our objective was to describe the allometry of this size-selective foraging in juvenile Atlantic salmon, Salmo salar of Catamaran Brook, New Brunswick. We compared paired samples of the stomach contents of 46 salmon (age 0+ to 2+; fork length 2.9–14.5 cm) with drift samples collect...

Wing sails offer a different design challenge to those of more conventional soft sail rigs. This study was undertaken in order to assess which parameters influence wingsail performance of C-Class catamarans, and to what extent, the results from the wind tunnel can be applied in the design developments of future wingsails. A combined wing sail and Cclass catamaran was tested in the low-speed sec...
