The function of flanking rudders:
When sailing ahead, one steers with the main rudders of a vessel, the flanking rudders are not operational at that point. If one sails backwards, the propeller turns in the opposite direction, this is when one should steer with the flanking rudders. Flanking rudders are essential if one cannot make a turn with the convoy, which results in lots of steering and manoeuvring forwards and backwards. Conventional flanking rudders are always present, resulting in extra resistance when not used.
The function of FLEX Flanking rudders:
When sailing ahead, one does not need flanking rudders, this is when the FLEX Flanking rudders are retracted into the vessel hull, which eliminates unnecessary resistance. This results in significant fuel savings. If one has to sail backwards to manoeuver, the FLEX Flanking rudders can be deployed to generate extra manoeuvring power.
Van der Velden Marine Systems has developed an innovative retractable tunnel system, especially developed for inland vessels.
The concept behind the Van der Velden® FLEX Tunnel is its ability to retract.Read More
