A guiding appendage positioned under the ship body, parallel with its longitudinal axis (LA), of sailboats and similar floating vessels, whereas said guiding element comprises a core element (5), fastened to the ship body, parallel with its longitudinal axis (LA), and a flexibly deformable shroud element (6) enveloping the core element. On both sides of the core element (5), between the core element (5) and the shroud element (6), a chamber is being formed, which is filled with a pressure medium capable of streaming. The chambers filled with pressure medium on the two sides are independent of one another, and each is connected via a conduit (22, 23) to a pressure controlling device (24). The shroud element (6) is a flexible plate and, at least upon increase of the pressure of the pressure medium, the external shroud profile is a streamlined form in the horizontal cross-section of the guiding element (4). The chambers act as deforming elements (18, 19), with sealing means allowing the parallel and perpendicular motion of the shroud element (6) relative to the core element (5), or arranged in between them. The shroud element (6) is of changing flexibility in the direction of the longitudinal axis (LA) of the ship body, its flexibility being the biggest in the vicinity of the biggest width (w<SUB>max</SUB>) of the streamlined form and decreasing gradually towards the leading and trailing edges (LE, TE), respectively, of the guiding element (4). The invention relates further to a guiding appendage for sailboats and similar floating vessels including at least one guiding element positioned under the ship body parallel with its longitudinal axis, wherein the guiding element (4) is coated with a thin elastomer layer (17) . |
