The couple had experienced problems with the steering gear and rudder, which made the vessel unable to steer at sea unless the wheel was constantly manned.
BMW said the steering gear was not correctly machined.
Replacing the steering gear should straighten things out.
Replacing the power steering gear assembly should smooth out the turns.
FORD Some 2012 Focus models may need a new steering gear.
Power steering gear was developed to solve the steadily increasing steering problems.
Most modern power-steering systems consist of hydraulic boosts applied to either the steering linkage or the steering gear.
Called the Autonomous Emergency Steering System, the feature would engage the brake and steering gear when radar detectors, cameras and laser sensors sensed an imminent collision.
A directionally unstable ship is easy to maneuver, while a stable ship requires less energy expenditure by its steering gear in maintaining a set course.
The point of linkage attachment to the steering gear must be placed so that it can move vertically with respect to the wheel mountings without turning the wheels.
However, large steering gear ratios made high-speed maneuverability more difficult, because the steering wheel had to be turned through greater angles.
