There are four types (A,B, update B,C) of the steering helm to choose, which can be matched with our steering wheel as well as the steering cable M66 type.
The Steering Helm is usually mounted on the dashboard of the boat/ship.
On the shaft of the helm is mounted the Steering Wheel.
The steering helm can be used together with the steeing cable M66 type. And the length of the steering cable depends on your requirement.
