Ship wakes: Kelvin or Mach angle?
, 2013 From the analysis of a set of airborne images of ship wakes, we show that the wake angles decrease as $U^{-1}$ at large velocities, in a way similar to the Mach cone for supersonic airplanes. This previously unnoticed Mach-like regime is in contradiction

A Fully Nonlinear, Dynamically Consistent Numerical Model for Ship Maneuvering in a Seaway
Modelling and Simulation in Engineering, 2011 This is the continuation of our research on development of a fully nonlinear, dynamically consistent, numerical ship motion model (DiSSEL). In this paper we report our results on modeling ship maneuvering in arbitrary seaway that is one of the most ...

Ship Domain in Various Visibility Conditions in Restricted Waters
Annual of Navigation, 2018 Ship domain is one of navigational safety assessment criteria. Its shape and size depend on many factors, including visibility. This article examines the influence of visibility on the shape and dimensions of ship domain in restricted waters.
