Determining the necessary speed for a vehicle to stay above water is complex and depends on various factors, including the vehicle's size, shape, and movement mechanics. The hull's design and surface roughness significantly influence buoyancy and stability. While dirt bikes can skim across water briefly, they require modifications like fins for added lift. The discussion highlights the challenges of applying these principles on Earth versus theoretical scenarios on the Moon. Overall, this topic underscores the intricacies of fluid dynamics in relation to vehicle design and performance.
