Description

A hull with a spare tiller

Technical Field

The utility model relates to the technical field of ships, in particular to a hull with a spare tiller.

Background Art

In ship design, navigation control devices are a crucial part, which ensures that the ship can navigate safely and accurately. Traditional ships usually use a mechanical connection to connect the tiller to the rudder, and the direction of the rudder is changed by turning the tiller to control the ship's heading. With the development of technology, modern ships gradually use electric or hydraulic drive devices.

Although electric or hydraulic drives provide more convenient and precise operation methods, they also have some risks and limitations that cannot be ignored. Among them, the most important problems include the risk of failure caused by the complexity of the system and the dependence on power supply. When the electric or hydraulic drive fails, the ship will lose the ability to control the rudder, which may lead to serious safety accidents.

To address this problem, we proposed a backup manual tiller device that can maintain basic navigation control even in the event of electric or hydraulic drive failure.
