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.
Claims8
A rudder construction for use in light vessels, comprising:
- an elastomeric rudder blade having a longitudinal aspect and being attached to the hull of the vessel, wherein the rudder construction is attached permanently to the hull of the vessel and is equipped with a thinned zone to permit a main part of the rudder blade to turn relative to the longitudinal aspect, as well as at least one flexible zone to create flexibility in at least part of the rudder construction, in a collision, and to permit the at least part of the rudder to bend laterally to a side.
A rudder construction for use in light vessels, comprising:
- a rudder blade attached to the hull of the vessel, wherein the rudder construction is attached permanently to the hull of the vessel and is equipped with a thinned zone to permit a main part of the rudder blade to turn, as well as at least one flexible zone to create flexibility in at least part of the rudder construction, in a collision, the flexible zone being formed of an essentially folded construction that permits the rudder blade to flex both laterally and forwards and backwards.
