Becker Twist

The Becker Marine Becker Twist is a flap-rudder steering component. It is normally installed at the vessel's stern connected to rudder stock, bearings and steering machinery. It is designed for generation of hydrodynamic steering force and enhanced maneuvering response. In operation, rudder and flap geometry alter water flow when the steering system changes rudder angle. The supplied entry states the source description as “High-performance flap rudder system”; this information is retained unchanged. Compared with neighbouring models, the relevant differences are rudder dimensions, flap linkage, allowable angles, stock/bearing arrangement and vessel-specific geometry; these must be confirmed from the installed documentation rather than inferred from the model designation alone. Service and survey attention should concentrate on blade/flap structure, pivots/linkage, stock/bearings, seals, clearances and impact/cavitation damage. For exact ratings, dimensions, tolerances, test limits and model-specific settings, refer to the manufacturer documentation for the exact figure.
