1. Floating dock for vessel propellers containing spatial split displacement element, submersed in water and sealed in its connecting edges and vessel elements, characterised in that it is composed of two identical mirror reflection spatial semi-pontoons (1), of open construction, having shape close to a regular trapezium, connected rotationally with each other in their horizontal axis and mounted together on a single, horizontal peg (2), constituting a bottom part of the adjustment mechanism, composed of fixed, sliding vertically twin guide rails (3), connected with each other at the bottom by means of a fixed traverse bar (4) and mounted slidably in two vertically rotating adjustment heads (5), fixed in a swinging manner crosswise to the vessel's axis (S), on the edges of the front part of a special displacement vessel body (6), U-shaped from top view, with a steering fin (P) of the renovated vessel (S) placed in the inner channel in a ready-to-use state , while the front wall of the semi-pontoons (1) is equipped with exchangeable sealing semi-shells (7), which are folded together and sealed in horizontal plane of the connection (L-L) of the semi-pontoons (1) in relation to the core of the vessel's (S) propeller (O).<IMAGE>
