Abstract

Rowing upgrade efficiency or the floating units (mainly sport boats) manually propelled by means of oars through outstanding amplitude and frequency of motion disturbance reduction and all this through implementation of rudder stabilizing device comprising at least one element 1 and element 2.

Description

MULTI-FACE RUDDER STABILIZING DEVICE OF FLOATING UNITS
The subject of invention is device which may be used on the floating units especially those rowing mainly by oars sport boats.
Disturbances of floating units motion are known chiefly on sport boats rowning mainly by oars.
These disturbances are met on the perpendicular surface to the water surface and penetrating floating unit oblong axis. Motion disturbances are characterized by own amplitude and frequency.
Device application according to the invention significantly upgrades rowing efficiency by outstanding reduction of amplitude and frequency of motion disturbances on above mentioned surface and facilitates to keep the course of floating units or their change.
Device is particullary specified on the illustration on which fig. 1 shows all its fixed or movable parts in axonometric view.
Existing in this device at least element 1 is fixed to element 2 in the immovable or movable way under definied ( α ) angle. Surfaces of element 1 and element 2 intersect. Element 1 diminishes amplitude and frequency of motion disturbances in a definite surface combined together element 1 and element 2 is rotary fixed in relation to the floating unit.
According to the invention mentioned device together with is combined elements keeps or changes direction of motion of the floating unit through element 2. As to element 1 it reduces significantly amplitude quantity as well as frequency of motion disturbances in given surface. Element 1 serves to keep inclination angle of floating unit oblong axis in relation to the level ( water level ).

Claims

C L A I M S
Multiface rudder stabilizing device for floating units installed on floating units propelled especially in rowing by oars in its concept characterizes that element 1 are fixed permanently or in movable way with movable element 2 localized permanently in a definite point of the floating unit,
Existing at least one element 1 ( first claim ) is localized on fixed in a permanent or movable manner on the element 2 ( second claim ).
