  • Patent number: 6684804
    Abstract: A rudder construction for use particularly in light vessels, for example, in kayaks, and including a rudder blade (1) attached permanently to the hull (11) of the vessel and equipped with a thinned zone (9) to allow the main part of the rudder blade to turn, as well as with at least one flexible zone (17) to create flexibility in at least part of the rudder construction in a collision. The rudder construction is manufactured essentially entirely from an elastomeric material. The flexible zone (17) is formed from a weakening in the material thickness of the rudder construction and permits at least part of the rudder blade (1) to bend to the side.
