In this period, ship hydrodynamics research converged on integrating adaptive control concepts with moving-mesh and free-surface simulation techniques to improve robustness of steering, hull-water interaction predictions, and dynamic response under sea conditions. The work around model reference adaptive control enabled disturbance-robust guidance ideas in autopilot-like systems, while moving mesh formulations such as Arbitrary Lagrangian-Eulerian methods and conservation-aware finite-volume schemes significantly improved the fidelity of hull-fluid simulations on evolving grids. A focus on water entry phenomena, jet flow approximations, and the emergence of three-dimensional effects highlighted the shift toward more realistic, 3D hull analyses rather than purely two-dimensional models, shaping how researchers address hull performance in dynamic environments. Historical significance: The period displaced static-grid limitations by embracing mesh adaptivity and conservation principles in naval hydrodynamics, laying foundations for modern ship CFD and integrated control-hydrodynamics tools. Breakthroughs in water entry modeling and three-dimensional lift/drag analysis established groundwork for accurate slam-load predictions and resilient hull design under complex flow conditions.
