Requesting detailed technical insights on the design evolution and performance characteristics of Glastron speed boats. Specifically, I am interested in discussing the engineering principles behind hull design optimizations, material choices, and powertrain configurations over successive models. How have modifications in hull geometry and overall weight distribution impacted stability, maneuverability, and fuel efficiency? Additionally, is there any documented analysis on stress factors and hydrodynamic performance during high-speed operations? Empirical data or case studies that detail the correlation between design alterations and operational efficacy would be particularly valuable for a comprehensive technical evaluation.
