Inboard Through Hull Rudder and Shaft


A digital download plan set for an inboard, through hull mounted rudder system.



This through hull mounted driven rudder system is a design by Berryer Design. The rudder profile is the same of that on the Transom Mounted Cable Driven Rudder System of Rocket, the Gentleman’s racer. This through hull rudder design would be suitable for use on Rocket if a higher shaft angle was used, pulling the rudder mounting inboard.

The through hull, inboard mounted rudder steers via a hydraulically driven ram, operating a tiller secured to the top of the rudder shaft. This classic boat steering is designed to be cut from plate and welded and the shaft could be altered in length to suit a range of applications.

The system would be adaptable for other boat designs of similar size and performance but may require modification. If you would like to check the suitability of this system for your boat then feel free to contact me.

The file comes in a .STEP format 3D model of the complete assembly as well as .pdf drawings and a .dxf profile for the blade shape and is available for instant download at the checkout. If you think you need the model converted into a different file format then please contact me.
