Precision guidance and control of an autonomous, wingsailed catamaran has been demonstrated by Harbor Wing Technologies’ X-1. Based closely on the Atlantis project, the X-1 is larger, more capable version. The platform is a modified Stiletto, a 9.1 m (30 ft) catamaran, experimentally capable of navigating along straight line segments between GPS waypoints and achieving line tracking with averag...

Under the strict binary foot parsing (Kager 1993), stray elements may occur between bimoraic feet. The stray element may be associated to the preceding foot or following foot at surface level. Stray element adjunction is the mechanism for achieving surface exhaustivity. Each language has its own unique mecbanism of stray element adjunction in order to achieve surface exhaustivity. In Japanese l...

The effects of limited water depth on the hydrodynamic performance a catamaran with full-scale dimensions and geometry WAM-V 16 unmanned surface vehicle operating in shallow waters are investigated using an incompressible URANS-VOF solver OpenFOAM®. Simulations flow associated passage have been conducted for range speed several to intermediate depths under free trim sinkage conditions. resistan...
