In the drive to reduce the full consumption of inland vessels, one of the main limitations, the risk of propeller ventilation was investigated. Aim was to reduce the resistance of the vessel, while at the same time an acceptable margin against propeller ventilation had to be assured. A typical inland vessel has up to 2 high loaded relative large propellers, which tip regions in the lighter loading condition are above the water line. To eliminate the risk of propeller ventilation, these ships often have inbuilt shape features such as tunnels and skirts, only having the intention to avoid air being drawn by the rotating propeller.
