What does a plastic sheet rudder look like

Similar in shape to traditional metal rudders, they are usually long or flat, fixed at both ends to a connecting rod, and connected to the tiller by a handle or stirrup. The shape and size of a plastic sheet rudder will vary depending on the brand, use and design requirements. But in general, it usually consists of 2-4 flat or curved plastic pieces, presenting a shape similar to a leaf or a fin, to realize the control and adjustment of the ship's direction.
