The Motion Of Vehicles In Water

The smooth sides and rounded outline of the shape do not disturb the flow of water and do not cause turbulence behind the object. Turbulence causes drag in a vehicle. The hulls of vehicles that are immersed in water are streamlined so that the vehicles can sail faster through the water.

The center of gravity of the vehicles in water must be below the water level so that the vehicle is stable and balanced when moving on water.
