The Hebel’s rudder blade, made by Mapalu is a great example of a device that simply and cheaply increases the capabilities of known design solutions that have existed for centuries.
Like all products developed and researched by Mapalu, it is an innovation characterized by novelty features on an international scale. It is a proprietary construction characterized by the shape of a narrowing double-sided through box constructed by the walls constituting the rudder blades. It will be able to be used both in newly produced units and as part of modernizing existing units. It provides control in all sailing conditions for all types of vessels, regardless of the type of propulsion.
