DE202005000081U1 - Rudder arrangement for all types of water-borne craft, e.g. yachts, has prow rudder close to prow in addition to stern rudder, second prow drive near prow rudder, reduced keel, mainly required to carry ballast, common rudder control system - Google Patents

Abstract

The rudder arrangement has a prow rudder (R2) close to the prow in addition to the stern rudder (R1). A second prow drive can be arranged near the prow rudder. A reduced keel (K2) is fitted, which is mainly required to carry ballast. Both the stern and rear rudders are operated from a common control system.

Description

In The following description will be by way of example only refer to a yacht, but all information is for each moving on the water surface Vehicle (ships and boats) valid, independently of the drive.

Sailing or motor yachts of conventional design have a rudder and a drive propeller ( 1 ) at the rear. This makes them sufficiently maneuverable.

Turn- and docking maneuvers in a small space but are very difficult. In particular, require docking maneuvers sideways movements with very little longitudinal movement.

at Sailing yachts need the unwanted sideways movement by a deviation of the driven course from the actual one (desired) Course compensated (the ship is diagonal to the course line!); this worsens the actual Hydrodynamic property of the yacht.

Of the The invention defined in claim 1 is based on the problem that the turning and the sideways movement without unwanted longitudinal movement and to ensure turning in a small space (rudder positions PH1 with PB1), as well as when sailing the unwanted sideways movement without an inclination to ensure the yacht to the course line (Rudder positions PH1 with PB2).

All the above problems are solved with the features listed in the protection claim 1 ( 2 ).

An advantageous embodiment of the invention is in 3 shown. The additional nose drive allows continuous and faster docking motion (rudder positions PH1 with PB1) and turning (rudder positions PH1 with PB2), without alternating forward / reverse movement.

Some possible maneuvers are in the 4 shown. In maneuvers M1 and M3, the rear and bow propulsion are simultaneously activated for forward and reverse movement.
